Homemade 83-key keyboard

Introduction: An 83-key keyboard based on Atmega32u4-au. I originally wanted to use the reverse L key to enter the Enter key. But I forgot to set the control of the balance bar, so I can only use the rectangular Enter key. Brothers who are interested can change this position by themselves.
