Description:

In some projects with Arduino/Python, a full-featured “Keyboard” instead of a membrane keyboard, is needed. there the Mini Wireless Keyboard is a good solution, but sometimes still too big.

This mini Blackberry Q10 keyboard could be a good solution. JoeN, from the Arduino forum, taken us a good suggestion, and also the related usage examples, to use this mini keyboard in the project(https://forum.arduino.cc/index.php?topic=355709.0).

The keypad is a bitch to the interface because it uses a 0.4mm pitch connector on flat flex, not really all that hobby friendly. And it worked pretty well as hobbyist repellent as near as I can tell, until now. I have been able to build an adapter board to convert the appropriate connector to DIP, interface it to an Arduino, determine the pinout, and create a short demonstrator sketch to prove the interface and allow the user to type text out to an OLED.
