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.

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.

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 TinyGrid85 - ATTiny85 board with prototyping area
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.

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.

Respectfully,

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.

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.

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! :)

Thanks for the good review.
Here's the Wiki page for 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.
