Mechanical Keyboard - Mechagodzilla Arduino Pro MIcro

thingiverse

Motivation: I can't find in my country Teensy 2.0, but I have Arduino Pro Micro. The problem with the Pro Micro is that it has only 18 pins, and you need to build matrix with this limitation. The matrix is 6 X 12, resulting in 72 keys. The wiring is as follows on the images, the layout is the same as the original. To flash the pro micro you must do the following: - open device manager and find the pro micro - reset the pro micro first time (short reset + ground pins) - see to what port it changed - reset again and execute ```avrdude.exe -p atmega32u4 -P COM3 -c avr109 -U flash:w:promicro.hex``` Where my pro micro is on COM PORT 3
