Does what it's supposed to.

For 4-Channel Opto-Coupler Card (OPTOFAST)

I was looking for an off the shelf solution to safely interface 5v triggered SSRs with the GPIO on a Beaglebone or Raspberry PI, and I found this.
This board has good isolation between the output and input, and excellent documentation in the event that I need to repair it in the future.

useful product

For ESP32 VGA, Keyboard, Mouse Card V2 (PCB Only)

Answer my questions in detail, being a new user of microcontroller.
Haven't assembled yet (bought only the board), but expect no surprise with the quality of documentation !

Interface PCB

For Z80, 6502, 6809, FPGA Multicomp PCB (EP2C5-DB)

A very good transaction all round, good fast service and a high quality printed circuit board. Thank you.

Very nicely designed boards, works well and easy to build.

For ESP32 VGA, Keyboard, Mouse Card V2 (PCB Only)

Great platform for the ESP32/ FabGL, easy to construct. Just be careful to grab the BOM for the latest version of the board.

Super nice seller, helped me out with the SD card sockets which were backordered thru vendors.

Quick shipping, well packed too.

Great support

For I2C Multiplexer for the Raspberry Pi (RPI-I2C-HUB)

While I haven't thoroughly tested the part I purchased, the communication and shipping were great. Would buy from seller again.

Terrible

For Optically Isolated USB-FTDI Interface (OPTOUSB)

Worst design ever for the price that you pay, got one board of revision one with patches. Purchased expedited shipping, been shipped late. At least they replied, later, to my email. Link to documentation on their website does not work. Claim board works with either 3.3 V and 5 V. At 3.3 V current through diode is not enough.
Suggestion: stay away.

Response from Land Boards, LLC | Sept. 18, 2019

Marco, I am sorry for your experience. We ship as soon as possible but like other small makers we do builds and shipping in our spare time. We received your order on the 9th and shipped on the 14th. We did ship with the 2-3 day shipping as ordered.

I did not intend to send you a board with wires so that was definitely a mistake on my part. Again, sorry for that.

As to the 3.3V operation we tested the board with both options (3.3V and 5V) and should have listed this as a build option since there's no good value for the bias resistor that works for both 3.3V and 5V. The Tindie listing does indicate 5V but would certainly could have made it clearer. We updated our Wiki page to show 5V operation (and removed the 3.3V note). We plan on updating our page to make this an ordering option rather than assuming 5V operation.

If you are unhappy with the operation of the card, feel free to return them for a refund.

Again, sorry about our performance as a company on your order.

Very happy with this 64/128 Channel Digital I/O Card

For 64/128 Channel Digital I/O Card (DIGIO-128)

I'm building on a RPI project that needs a lot of GPIO and this product was exactly what helped me out.
The shipping to Germany went relatively quick and I unpacked it in good state.

I'm not really experienced on this field (I2C) and had some troubles and questions so I contacted the seller. He really gave his best to help me solving my problems and answering my questions, very patiently. So that leaves me as a very pleased and happy user of this device.

I can certainly recommended this product.

Very happy with this Multiplexer

For I2C Multiplexer for the Raspberry Pi (RPI-I2C-HUB)

Thomas | May 1, 2019

Simple, well built device that works exactly as intended.

For Raspberry Pi Console Card (RPI-CONSOLE)

The device works exactly as intended and fits snuggly into the Raspberry Pi GPIO slots on the top side.

Jim | April 23, 2016

Nice expander for lots of I/O's

For 64/128 Channel Digital I/O Card (DIGIO-128)

This is a great board for expanding out to address vintage computer systems, or other boards which require more than a few I/O's to work.

I plan to use this to animate via simulators a number of front panels for various systems, such as DEC PDP 11s and the like.

Simon | March 8, 2016

Fantastic!

For Arduino with screw terminals (Screwduino)

This is something I've been waiting for for a long time. Obvious - but still nobody made one.

I'd like to see one with the little spring terminals they use on loudspeakers too - and maybe with a USB socket. As it is, it's still great for rapid prototyping.

Bill | Feb. 15, 2016

This worked for me

For Coax Tester - Fast Edge Pulse Gen. (50 or 75 Ohm)

Suddenly my 40-meter yagi at the end of a long feedline started showing a very high SWR. The antenna looked good using binoculars. So where was the problem? Lots of the transmission line cable was buried underground.

This handy TDR pulse generator exactly determined the location where the defective connector was located. Turns out to have been just after the antenna switch located at the base of the tower.

This device worked for me. I'm sold.

Effective small project breadboard with simple CPU

For ATTiny85 board with prototyping area (TinyGrid85)

I bread-boarded two projects for my neighbor's Lionel Train Set and then I saw this option which would have saved me time, especially since I had to procure bare PCB breadboard. I bought two for my next unknown projects just because it will make it easy. Mike Heslop

a little bit of info on which serial port is use..

For Raspberry Pi Console Card (RPI-CONSOLE)

More info on serial port used.
could be anyone of several ports available
on the connector.
figured out which one, but would have been better
to have some info on which serial port was connected.

Response from Land Boards, LLC | Aug. 28, 2015

Dale,

Sorry for the problem. I'm not sure what the issue you had was. The Raspberry Pi only has one serial port connection on the connector. Transmit is on pin 8 and receive is on pin 10 of the Raspberry Pi connector. See the pinout on this page -

http://pi.gadgetoid.com/pinout

If it's the serial port on your computer that is the question then we gave the information on how to run Device Manager (assuming you are running Windows on your computer) on our documentation page.

Backed on Kickstarter, then bought 4 more from Tindie

For Raspberry Pi Console Card (RPI-CONSOLE)

I backed this device on Kickstarter and then I bought 4 more from Tindie. I usually use a USB-TTL cable but this makes easy enough that I don't have to keep reminding people what order the pins go in. Just snap it on, install the driver, and plug in to your USB port.

Response from Land Boards, LLC | Aug. 28, 2015

Thank you for the great review. This little card just does what it is supposed to do.

BOM Would be a Tremendous Help

For 3.3V/5V Beaglebone Sensor Conn Cape (BBB-GVS)

I bought the bare board because I wanted to practice my SMT soldering AND because the populated board was back-ordered. Unfortunately, I only skimmed the available documentation - "Hey, here's a board layout and a list of parts!" - before ordering. The next day when I tried to order from the list of parts I discovered many were vaguely specified: fuse 0805, LED 0805, etc. What current rating for the fuse? What current rating for the LED? What package for the EEPROM?

About 3/4 of the parts are completely specified. The other 1/4 are underspecified.

Since I cannot tell if the product works, I am unsure on how to rate it. I also have not followed up with the vendor to see if there is more information available. I rated both mid-pack.

Response from Land Boards, LLC | April 15, 2015

Jeff,

Sorry that you had some difficulty in determining what parts should be used on the bare board. Sounds like you found our Assembly Sheet page at: http://land-boards.com/blwiki/index.php?title=Beaglebone_Black_Assembly_Sheet

It is true that not all part numbers are specified in detail on that sheet. Hopefully we can help:

EEPROM PN: CAT24C256WI-GT3
Fuse: PTS120615V050 (it is in a 1206 package not an 0805 as indicated above). 1/2 Amp fuse.
LEDs are typical 0805 red LEDs. The series resistor value is specified on the assembly sheet. PN: LTST-C170KRKT

If you need help with parts other than these three, please reach out and let us know.

Great Product

For Coax Tester - Fast Edge Pulse Gen. (50 or 75 Ohm)

As advertised. Very fast rise time and clean waveform. Optional enclosure might be nice but no obstacle for the tinkerer. If you are expecting loads of documentation the designer is expecting that you know what you are ordering! :)

Response from Land Boards, LLC | March 14, 2015

Thanks for the good review.

Here's the Wiki page for the card.

http://land-boards.com/blwiki/index.php?title=PulseGen

The page links to another page with a good description of how to use the card.

Fast Edge Pulse Generator - works well

For Coax Tester - Fast Edge Pulse Gen. (50 or 75 Ohm)

This small circuit board produces a 50 ohm square wave with a frequency of about 300 Hz. I have an ultrasound application that requires a sharp pulse like edge, rise time of 5 ns or so. When I connect the circuit to a 5V DC supply, I get an almost 5 V step in something like 2 or 3 ns.

I've been using this board for a few days now and have not had any trouble.

Function generators that can generate this kind of sharp edge at 50 ohms cost a lot more than this little board, take up more space and use more power.
