A simple, DIY-friendly plan.
- Raspberry Pi 2W
- Two-way communication team
- 2a Small fan (choose from 2cm-4cm)
- 0.96" OLED screen (You can also buy a larger one, but make sure the cable order and dual-port board are consistent)
Steps for operation:
- Simply insert the Raspberry Pi and duplex board (if you don't have soldering skills, ask the seller to solder the headers for you, or purchase pre-soldered headers).
- Through-hole component placement (also requires soldering on the dual-layer board)
- For the position-mounted fan (also needs to be soldered on the dual-board).
- Directly power and then debug (no need to add a battery, isn't a power bank more powerful than a battery?).
