- Plug for 12/18/24 V.
- LM7805 (DDPAK/TO-263 for 5 V @ 1.5 A) µC power supply.
- Minimal connections for ATMEGA328:
- Serial communication and programming with FTDI board:
- ISP communication for burn boatloader (and programming if you want it):
- Step-down converter to 5 V:
- Resistor + Capacitor: 0805
