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 !

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 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

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.

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.
