Great little board. Great tool.
For ATtiny841 dev. board w/Optiboot (assembled)
I am using this board to help me port a project over from Attiny84 code base to the Attiny841. DrAzzy: Do you have any tips and insights on doing that ? Maybe a list of differences between the 2 processors ? anything will help. Thanks!!
Response from Azzy's Electronics | Feb. 7, 2019
Thanks!
That's a good suggestion - I hadn't thought of writing up a guide to migrating to ATTinyCore from other cores, and to ATTiny841 from ATTiny84.
The main differences are:
ATTiny841 has two hardware serial ports, named Serial and Serial1; they can be used like the serial ports on any other AVR through ATTinyCore. The ATTiny84 has none (though if using my core there is a builtin software serial implementation that uses the ACO vector, so it can be used without interfering with use of PCINTs for other purposes like the SoftwareSerial library would - see the ATTinyCore documentation for details - probably not relevant to you).
ATTiny841 has an additional 16-bit timer, timer2, which is identical to timer1. The PWM pin assignments are also more flexible - you can move the PWM outputs around between pins; this can allow some behavior that could never be achieved on most AVRs (unfortunately the coolest thing I did with this is covered by an NDA, so I can't go into further detail)
The ATTiny841 has a hardware SPI, and hardware I2C slave interface, while the ATTiny84 has a USI.
If using the Arduino IDE with ATTinyCore, you can use unmodified libraries designed for SPI or I2C devices, and the version of Wire and SPI libraries included with ATTinyCore for the 84 or 841 (these versions of the library automatically use the correct implementation of I2C or SPI for the hardware, and provide a compatible interface, so no changes to the library are needed). With the Arduino IDE and other cores that support the ATTiny84, you needed to use a different library for SPI/I2C that used the USI, and modify the library for the SPI or I2C device to make use of that library instead of the standard Wire or SPI library. If you are not using the Arduino IDE, you need to handle this yourself (the most notable hardship is that I2C master requires a software implementation of I2C - ATTinyCore handles this for you in Arduino-land, but if using Atmel Studio or other tools, you'd have to do this yourself)
On the ATTiny84, the internal oscillator is pretty close to 8MHz across the whole operating voltage range (ie, close enough for serial to work), but strongly temperature dependent (particularly on the low end). On the ATTiny841, the internal oscillator is very close to 8MHz across the whole temperature range below 4v, but the speed increases rapidly as voltage increases above that - such that above ~4v, it's not close enough for serial to work if you don't account for that (typically by adjusting OSCCAL). If using a crystal, which I recommend for any application where serial functionality is used (on any processor, not just this one), this is not relevant.
I've added an issue to ATTinyCore on github regarding this; you can follow this for updates on the progress towards more formal documentation. https://github.com/SpenceKonde/ATTinyCore/issues/285

It's a heavy duty mosfet
For 4-Channel logic level MOSFET driver 100A up to100V
I'm using these monsterfets and Arduino to control my aquarium pumps. A lot of turning on and off to try and create ocean currents and tide, with the key word being try. I was using smaller mosfets but they failed after several months. I guess I was running them too close to their rated max...These monsterfets with 2A running through them have all kinds of headroom. The temperature increase when they are running is only 2F, so I don't need heatsinks but I'm running a small load. A much better option than relays, IMO.

Nicely done!
For ATtiny1634 dev. board w/Optiboot (assembled)
TL;DR - All the love is in Azzy's ATTiny Core for the Arduino IDE. Buying his breakout boards helps to support him.
I'm incorporating a 1634 into a design I'm working on, because it has two hardware serial ports. I like to get an eval board up a running before I roll my own. Azzy's breakout board fit the bill nicely, the extra GND and VCC pins was a nice touch as I need a common ground for my motor drivers. While the project isn't open source hardware, Azzy's ATTiny Core MORE than makes up for it, and he includes the schematic.
BTW, I couldn't get Sparkfun's USBTinyISP to work and it appears I'm not alone, nor am I the type of person that will uninstall and reinstall everything just to get something to work. The AVRISP MKII works beautifully, kind of makes sense, right?

Thanks - glad to hear it!
The matter of ISP programmers and which ones work and don't has been a matter of some discussion. I have had similar messages from many users - people who swear that one or two programmers work great, but none of the others do. Unfortunately, there isn't much of a pattern to which the ones are reported to work, and which ones are reported not to. There is an open issue relating to problems programming with the USBTinyISP here - is this the problem you're having? https://github.com/SpenceKonde/ATTinyCore/issues/158

This set covers most all of the ICs and discrete components I need to tack up into a prototype.
Documentation? Really who needs that on this kind of break out board any ways....

Great product, here's some code samples to get started.
For LoRaWAN RN2483/RN2903 Breakout board (Assembled)
First off, great product, super friendly customer service, although not very helpful for any kind of "getting started" advice. Maybe, they figured, if you order these things, you'd better know how to use them? Anyhow, the breakouts arrived in excellent condition, and are super easy to connect with a Raspberry Pi Zero, or other embedded-Linux (or otherwise), micro controller.
These skeleton projects on GitHub, can be used to quickly test the connectivity of your UART connection to the RN2XX3 module, on eLinux. I hope they save someone else time in working with these terrific breakouts.
If using RPi3, or RPi Zero W, please note the UART is at: /dev/ttyS0
https://github.com/miguellan/python-lorawan-RN2XX3
https://github.com/miguellan/C-lorawan-RN2XX3
If they save you time, and you'd like to contribute, please do.
Thank you for making these breakouts, I highly recommend them.

Perfect for Teensy boards
For Mint-tin size prototyping board
I agree with Michael. I needed a carrier board for a Teensy 3.5 that allowed me to break out the pins and add some connectors for my I/O. The through hole version works perfectly for that. I was able to put the Teensy straddling the center. That left room for a double row of headers on each side - one row picks up the Teensy pins and the other picks up the breadboard area. Very nice!

Azzy's Electronics prototype boards are great.
For 2" x 4" Prototyping/Project boards
I can solder through hole projects tolerably well, but I am not an expert. At the moment, I have not attempted SMD soldering.
I've been buying the various breakout boards from Azzy's Electronics for some time now. I like the fact that these boards are plated on both sides, so that you can solder components on either side of the board. The boards are better made than many of the prototype boards I've seen.
I find the boards can tolerate de-soldering and re-soldering without the pads lifting off.
The 2x4" all through-hole boards are great for large builds where I have a lot of components, or two large boards. For example, I built a Teensy 3.1 with an Adafruit Audio FX sound board and speakers on the board. I did wish the ground and power pin spacing was every 0.1" instead of every 0.2". Newer boards like the mint tin boards now have the power/ground pins every 0.1".
The mint tin boards are great for medium sized projects. The layout of the connected rows of pins allows me to stuff even more components on the board than the Adafruit mint tin board. Plus you can get a case for the board at any grocery store :-)
The 1x2" prototype board is great for adding a Teensy 3.1/3.2 with just a few connections made via wires for a small build.
The various mini-protoboards are great for breaking out small components.
The small boards are typically mailed via US post office in a normal envelop with cardboard. My last shipment of the 2x4" and mint tin boards came via US mail with a tracking number. Since I live in Massachusetts (same state as Azzy's Electronics), the boards get to me quickly.

Simple SOT-23 MOSFET (six-pack, logic level)
For Simple SOT-23 MOSFET (six-pack, logic level)
I use these mosfets to switch 24V DC aquarium pumps on and off. Seven months later and everything is humming right along. I'm pushing around 1.5A through them and they don't even get warm. I'm using Arduino to control them. I love these little jewels!
At first, I used relays but I was switching so often their usable lifetime was too short.
Drazzy was very helpful, making sure I got the right product. I followed his advice- as a novice I would have been foolish not to. Drazzy is a great person to deal with. Couldn't be happier.

The board quality looks good with silkscreen and gold plated solder pads. Although definitely no rocket science a schematic somewhere would be nice.
Update: Arrrcchh must have overlooked it. There is a button with a link to the schematic! Apologies.!

Great product
For ATtiny1634 dev. board w/Optiboot (assembled)
This product is a very nice device suitable for intermediate between ATtiny85 and ATmega328P. Without much hustling, you can rewrite your ATmega code to ATtiny. Optiboot and FTDI serial pin header are also helpful to debug your code, too. The only weak point is the strength of PCB pattern. You need to be careful to solder something on this board. Anyway I love this.

Board to mount your RN2483 LORA module
For RN2483 breakout (bare board)
Neat board with provision for a voltage regulator and it has mounting holes! So many of the breakouts expect you to use a breadboard, fine for a prototype, but with a cased demo unit having a way to mount the board is essential. Modules soldered on with normal (fine) solder and fine tipped iron and I'd used liquid flux as well to ensure a good joint.
Please note in my ratings that there is in fact no paper documentation - so I've left the rating for the boards printed notation!

That's right - in order to ensure that documentation is always up to date, as well as to lower costs and reduce our impact on the environment, we do not include paper documentation. All documentation is available online linked to from this product page. If you have any questions, or find anything missing from the online documentation, please let me know and I'll get it fixed straight away.

I love the prototyping boards of Azzy's Electronics
For Mint-tin size prototyping board
I've bought various prototype boards from Azzy's Electronics, and they often fit various niches I need for electronics. Shipping is fast. I only do through hole soldering, but it is nice to have various options. I was going to buy some of the 1x1.5" mini prototyping boards, but they are currently sold out. I noticed there is now a mint tin prototyping board, and I ordered a few. I haven't actually soldered any yet, but it does seem well laid out, and it gives me more options than the Adafruit mint tin board, which is just laid out in breadboard fashion.
I tend to use Teensy's (LC, 3.2, and I just got a beta 3.6) these days. It was a nice coincidence that the Azzy board has 24 primary rows, and the new Teensy 3.6 will have 24 rows as well, and I can use the side sections for various add-ons (though if I go to town in adding stuff, I likely would go up to the 2x4" prototype board for the 3.6).
In thinking about having multiple servos and/or analog sensors, it would be useful if there was a variant of the mint tin board that had multiple power rails. A Teensy has 5 things you might want on a power rail (3.3v, VIN/5v, normal ground, analog ground, and analog reference), and for things like servos you might want an additional rail for external power.
I was thinking on the side that has 24 rows of 4 columns, if you reorganized it so that the ground row was 0.1" away from the other rows, and the last two rows were power rails instead of column rails, you could set up to have banks of either sensors or servos (there would 2 columns for a data pin and the connecting wire). It may even be desirable to break the power rails between the 12th and 13th column, so that you could have one set of pins for analog sensors (using 3.3v/analog reference and agnd) and one set for servos (using external power, normal ground, and data pin that have been level shifted).
Or alternatively, do this on the other side, and use the existing 2 pin columns and change some/all of the 3 column pins into power rails.
Here is what I meant by the second option where the 3 pin columns are converted to power rails:

Great board at a great price!
For 2" x 4" Prototyping/Project boards
This board is a superb fit for the LMB/Heeger TF-777 enclosure. The board layout and quality is also superior and lower cost relative to other prototype boards that are available from Adafruit, Jameco, and Radio Shack. Shipping cost and speed was also very reasonable. You can't go wrong dealing with Spence.

Nice compact board
For 4-Channel logic level MOSFET driver 100A up to100V
Nice board, not too small; and not too big. Easy to work with. The only (valid) comment I have is that there is only one mounting hole, would have liked two so it could remain more stable/solidly in place... The other is a personal issue -- the heat sinks don't face the same way; this is a personal issue (I also have to seperate my M&M's by colour...) and has no impact on the board or performance of said heat sinks or the mosfets...
I have not put a full load on it; but I think if you plan to go up to 100 amps; you may also want a fan on those heat sinks...
Great board, well worth it; great person to do business with. If you're looking for something like this; this is perfect.
