Power Requirements and usage
The DFRobot website suggests using their 12V-5A 60W AC/DC power adapter with a DC cable connected directly to the board’s power input connector. However, during our tests, we chose the USB Type-C port as the input and paired it with a GaN charger using a 9V 3.0A (27W) power adapter, which delivered good performance.
Power supply requirements as officially recommended by DFRobot.
- Input Options:
- USB Type-C (PD 20V) — for direct charging and operation.
- DC Jack (5.5×2.5mm, center-positive) — accepts 12–24V input.
