Keyboard PCB | Serial output | Alphabet Numbers Signs

$2 for 5PCBs (Any solder mask colour): https://jlcpcb.com

I had the idea to make a keyboard for Arduino or other microcontrollers that should already have the buttons encoded and only give a serial output with all the characters. It can send the full alphabet, upercase, special cahracters and numbers. Just using 2 wires for Rx and Tx of UART port. Baud rate of 115200 or change to other.
