PCBWay 3rd PCB Design Contest

Arduino shield for resistive keypad

The designed PCB is a shield for an Arduino Uno to connect a resistive matrix keyboard which will be used by our salesman as a proof of concept that the keyboards can be interfaced to a microcontroller by simplest means. The PCBs arrived in Switzerland super fast (after about 5 business days from the date of the order), the quality of the boards was excellent. The board design was approved without any problem. As it was a quite simple design, I didn't expect any problems. Thank you very much for the fast handling of the project!
