2. Electronics Production

1.Make your own development board a. Hardware selection b. Key parameters specified (I/O, I2C, etc.) c. Circuit design must follow standards (electrical rule check provided by CAD software can be used)

2.PCB milling and soldering a. Use CNC for milling; reference: https://link/ b. Soldering and assembly (use a multimeter frequently to check for shorts) c. Upload code to verify functionality

3.Document the process
