Good quality of pcb and parts
I was so happy when i got it as Christmas present , i have learn a lot , the computer work perfect after debugging about 2 days i recommend to improve the documentation witch exist online but is confusing and describe all the versions in one article and mix all together and the reader have to figure witch is apply for his item. Will be great to include a serial cable to connect with computer. i didn't finish yet the keyboard since i have limited time for my hobby. All in one is a great idea and i recommend to everyone witch want to better understand how computers work and how different parts is connected and work .

Great Fun! Excellent Quality
For RC2014 Pro - Homebrew Z80 Computer Kit
The soldering of this project was quite easy even for these old eyes. All through hole components. They mounted the only surface mounted component. I love the fact that it is so easy to build up a quick project that could be mounted to the back plane with simple pin headers. Powering it is as easy as plugging it into a USB port or if you prefer put a commonly available 5v regulator.
The developer Spencer is a treat to talk with on the RC2014-Z80 google group community and on Twitter.
If you are a electronics tinkerer make sure to get the 12 port bus as you will have plenty of room to make and add your own boards.

Works fine (-:
For RC2014 Classic - Homebrew Z80 Computer Kit
Very pleased with this kit. I had no problems building it and it worked first time for me. All components very well packed and all complete. I opted for the FTDI/USB serial lead. I had a few problems figuring out the pins. The instructions assume that you know what you are doing (-: So please note the following regarding the 6 pin header on the Serial I/O board:
pin 1 (on left as you view the component side of the board) = Gnd
pin 2 = RTS
pin 3= +5v
pin 4 = rx data
pin 5 = tx data
pin 6 N/C
Hope this helps

Ottimo!!
For RC2014 Classic - Homebrew Z80 Computer Kit
Pacchetto piccolissimo confezionato al meglio.
Prodotto che avevo già visionato al Maker Fire di Roma, come da aspettative.
Documentazione allegata minima ma si trova tutto online.
Perfetto ma devo iniziare il lavoro di saldatura e ci vorrà un po di tempo...

Can't wait to get started with RC2014!
For RC2014 Pro - Homebrew Z80 Computer Kit
I ordered everything (Pro kit) and just about everything else. Looking forward to being a contributing member of the RC2014 community. Thank you very much, Spencer!

Very nice Z80 kit

The best z80 kit out there!
For RC2014 Pro - Homebrew Z80 Computer Kit
What a cool kit. There are tons of options for add in cards, software, and 3rd party support. The community is great as well. If you're looking to get a z80 kit, this is one of the best out there. The fact that the bus is provided via headers makes it extremely easy to probe around and debug or just examine how the computer works.
The only complaint I have is that the pro kit doesn't appear to have up to date documentation. The website is still mostly focused on previous generations and the pro kit itself doesn't come with any documentation (or at least mine didn't). When I had an issue after assembly, it made debugging very cumbersome as I didn't understand how some of the modules worked. I assume this is simply because the pro kit is so new and will be fixed in time.

Nifty little Z80 Single-Board Computer. Easy to build & use.
For RC2014 Mini - Single Board Z80 Computer Kit
Received my RC2014 mini quite quickly, which was faster than I expected for UK to US shipping. Parts were well packaged and everything was ready to assemble. My only complaint was that the included printed diagrams were black-and-white printouts of evidently color pictures. The resistor color bands were impossible to interpret in the black-and-white photo, and the text labels were also very hard to read in some places. I ended up going to the website just to double-check everything. I color printout would be a great improvement.
Other than that, assembly was pretty easy and straightforward. Please be sure to unpack ALL the parts and lay them out before beginning—a few items were "hiding" in between other parts, leading me to wonder if they were missing before I discovered them. Sockets are included for all ICs, and there are a variety of different headers you can use depending on your application.
A USB-to-5V "barrel plug" cable is included, which lets you power the RC2014 mini directly from a USB port. There is no voltage regulator on board, so BE CAREFUL not to plug a 12V or other power adapter into the board!
You'll need a separate "FTDI-like" USB-to-Serial adapter in order to communicate with the RC2014 mini (everything is serial console I/O). If your USB-to-Serial adapter can provide 5V power, you can use that to power the RC2014 mini by setting a jumper, thereby dispensing with the USB-to-5V "barrel plug" cable. I purchased a couple of the following adapters on Tindie, which worked flawlessly:
https://www.tindie.com/products/maxtch/fused-ftdi-free-usb-to-uart-adapter-5v-m180v3/
All in all, a fun little project that was pretty easy to assemble and get working. Had my first BASIC program running in no time.

Very happy with the RC2014; great kit!
For RC2014 Classic - Homebrew Z80 Computer Kit
Received the RC2014 full-monty kit neatly packaged in a small box. Everything was included. Clear instructions on a printed leaflet but used the PDF from the website since it has the actual color codes. Was able to put it together in a few days, had a blast working on it. Lot's of soldering though!
My RC2014 did not work on the first try so needed to use the troubleshooting guide. It turned out that my soldering job was not that great, some pins seemed to be connected properly at first glance but turned out to make insufficient contact. Checked & fixed all joints and plugged in the power: and it works! This first time you see actual messages being sent from a computer you put together yourself is a great moment :-)
So all-in-all a great kit; especially the fact that all components are on their own separate board. The backplane als make it very nice to see what is going on and how the components communicate. Also the fact that there is a nice ecosystem with different community members making extension boards & howto's etc makes this a great choice.
Started with small basic programs, now testing with C programs using z88dk via the hexloader. Looking forward to more experimenting with it!

Well after being put to together by an electronic engineering tech of over 25+ years and having the all the jumpers in place with the ftdi cable correctly installed.
Powered the unit up with an upgraded 5vreg (aka Recom R-78C5.0-1.0) and all blue leds, the unit run perfectly with a debug terminal program made by one of the guys here (no putty for me). Going to be doing alot with this as I do have a GU256X128D-3900 plasma display to play with: (https://www.ebay.com/itm/NORITAKE-ITRON-DISPLAY-GU256X128D-3900/122630823248?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649)
Going to try a non volatile ram and probably add an Intel Can 2.0v chip to it as well as a sound card later...
Wish someone would make a basic interpreter for an ARM STM32F407IG part as I am trying to make my own version of a basic computer using this as an output:

Awesome Z80 CPU kit. Nice modular design. Easy to build.
For RC2014 Pro - Homebrew Z80 Computer Kit
I have significant experience building homebrew Z80 computers. The RC2014 kits are very nice and modular. They go together easily and are well documented. Operation is completely reliable. Kit was shipped very quickly and was well packaged. RC2014 community is vibrant and helpful. This has been a great experience!

A great upgraded board for the RC2014.
For Pageable ROM Module for RC2014 Homebrew Computer
Delivery was next day, the ROM board came well packaged. All components came with the exception of 2 minor components a capacitor and a 14 pin socket (mistakes happen). I emailed Spencer and he will be sending these components to me asap.
The board itself is a piece of art, the silkscreening is bright and clear the component placement couldn't be any clearer. The components are of the highest quality and the instructions couldn't be clearer. If I can follow them any one can.
The build went without a hitch took me around 15 minutes to assemble the board and it looks great. If you do manage to get stuck on whatever part, Spencer is very approachable and is happy to help.
Overall the board is well thought out, excellent quality and a breeze to build. The RC2014 is aimed at the home enthusiast weather being a complete novice getting into computing or the intermediate electronics hobbiest.
I really like this board it gets 10/10 from me.

Overall a very great board!
For Backplane Pro for RC2014 - Z80 Homebrew Computer
The enhanced capabilities to expand to 12 boards is profound. Also, the secondary bus is great except for the limited number of 5 provided. I love the external power and the on-off switch. I also think the idea of providing wires that can be cut or left in place should be done with the 8 position back plane. Overall it is a great back plane and when I plugged in all the boards for CPM it came up nicely.

Proto board connects to only 39 of 40 backplane signals
The board only connects to 39 of the RC2014 40 backplane signals. It is too narrow to accept the 40 pin header supplied. The missing signal connection is in the "SPAREx" signal group. So, if you do not need the last signal in this group, the board is still quite usable.

great for developing your own "rom" image
For RC2014 SD Memory Dump Module
This has to be probably one of the most complex boards to build, there is a fair bit crammed onto this one.
I did struggle with this one, eventually needing to re flash the avr before it burst into life.
its possible to use it with a rom module installed and in fact it its most stable like this
on a ram only system it can be quite hit and miss, and with the the star trek rom for
example I haven't been able to get working, even the ones that have worked it will
take multiple goes before it will work - this is a known issue and I'm confident its
been worked on but it is something you should bare in mind...

For Pageable ROM Module for RC2014 Homebrew Computer
The usual great quality PCB, construction reasonably straight forward.
the board allows great flexibility not only in page start but also size
choosing the basic language rom allows your machine to boot into basic just like most of the home micros of yesteryear!

You only bought an rc2014 to tinker...
This is definitely a useful board to tidily bring out the connections you need for your own device, due to the small form factor of "standard" rc2014 boards the amount of circuitry you can get actually on this board is potentially quite limited, but never the less this is useful for your own experiments

simply does what it needs to
For Z80 CPU v2.1 for Enhanced Bus RC2014
The is basically just the Z80 with most of the bus decoding etc taken care of by the modules themselves, as a result this has to be one of the simplest boards to build. start with this one!
PCB quality is good, with decent solder resist, but in common with most of the modules the 39th pin is very close to the edge of the board

For Serial I/O Module For RC2014 Z80 Homebrew Computer
Simple circuit does a rather important job, I'd recommend a FT232 usb> ttl serial to use with this as my hateful soon to be destroyed CP2102 based module didn't like it at all!
In future this board could maybe have its own crystal and it does have spare inverter gates that could be used for this, doing this should allow the Z80 to be run at a different frequency... 10mhz :-o

small board, simple function
For Clock Module For RC2014 - Z80 Homebrew Computer
I chose not to bother with the reset switch and its resistor, relying instead on the reset switch on my backplane
This board is very small and you should probably put the crystal in first, you really want as short as possible legs as possible on a crystal to avoid issues and when the crystal is flush with the board it interferes with the edge connector, which I had to basically sit on top of the flange of the crystals case. A board just a tiny bit larger and this wouldn't be an issue.
Care should be taken when locating this in the backplane as its plugged in half way along an edge connector
I'm not entirely sure this board wouldn't be better integrated into the CPU board, if you wanted to change clock speed at a later date you could always "mod on" a board like this to the serial IO module (which relies on this specific frequency) - it could be argued the serial module should have its own crystal... but there are pros and cons as always to each approach

The real heart of the system
For Backplane Pro for RC2014 - Z80 Homebrew Computer
As usual the PCB is of good quality with decent solder resist.
I'd have preferred to have had enough of the extended connectors to fully populate the board just to give as much flexibility as possible.
This could be a fault with my assembly but if I leave plugged into USB power but switched off, the cpu stops but the RAM seems to retain its contents - I need to investigate this further!
By the time you have soldered all the connector sockets to this board you will have had *lots* of soldering experience :)

Simply a good kit
For RC2014 Classic - Homebrew Z80 Computer Kit
Usage is pretty straightforward, even if you only have basics in electronics. Building it does not take a huge amount of time if you have some soldering experience (it is still very simple). For anyone interested in old computers and electronics, it is very nice and quite satisfying to get it up and running (at least for my part).
The only thing is that the documentation, though well written, can lack some precisions on certain points. But this is not a big issue, you still can figure it out with a bit of research, and I can have missed something.
Overall this is product is simply awesome, I am still experimenting with it and I think I will for quite some time. Delivery was fast and it was well packed. I just recommend it.

It appears to be a great product, still working on it.
For RC2014 Classic - Homebrew Z80 Computer Kit
I had built 2 Z80 systems in the 70's and decided I wanted to build another. Your product was the best I looked at. So far the projects going well.

It is a great product!
For Backplane Pro for RC2014 - Z80 Homebrew Computer
I just finished soldering the sockets and am in the process of checking continuity. I think that it has been well designed and well made.

Fast delivery and good packaging.
Almost easy to mount (I had to read twice as my english wasn't good enough).
A good buy !!

An excellent gateway into retro computing
For RC2014 Classic - Homebrew Z80 Computer Kit
It has been a long time since I've done any electronics so I was a bit apprehensive about getting this at first. I ended up biting the bullet and it was worth every cent.
I found the assembly to be relatively straight forward and got up and running within about 4 hours. I've spent some time getting a C compiler set up and have been writing short programs and even a game for it which has been great.
If there's any negative it's that there weren't any jumpers included with the full-monty kit like I would have expected. Luckily I had a few floating about.
Overall this is a great kit which I will recommend to anyone wanting to learn more about computing.

To be used with cp/m
For Compact Flash Module for CP/M RC2014 Computer
I like this module, it's surprisingly simple. The soldering is easy, too, except the surface mount part, the CF card holder itself. But with a good magnifying glass you can do it :-)
The quality is very good, the seller very patient and helpful!
