The main library for it is available and well-known on the Internet, but requires a bit of skill to get working. Cons:7-segment display was very bright. This could be considered a pro in some cases though. Also, the cable connected... Read more

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month Pros:Can be used as simple keyboard and 7-seg LED monitor. Theoretically it is possible to extend the module to 24-keys keyboard by soldering 16 other keys to existing 8 keys. Cons:On the card are activated only 8 keys from 24. Also standard Arduino library support... Read more

Displays are red, LEDs are red-green (green glows less than red when using 3.3V, remember this), buttons are very responsive. A perfect I/O gadget, as uses o... Read more

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:So easy to interface - takes only 3 pins to control everything on the board. Existing library makes displaying up to 8 LED digits, turning the LEDs green or red, and polling the buttons very simple. Can even be daisy chained to more units if you need more swit... Read more
