Power Supply Options
^^^^^^^^^^^^^^^^^^^^
There are three mutually exclusive ways to provide power to the board:
2021-09-17 02:42:50 -04:00
- Micro-USB Port, default power supply
- 5V and GND pin headers
- 3V3 and GND pin headers
2020-10-12 06:03:51 -04:00
2023-08-10 00:09:21 -04:00
It is recommended to use the first option: micro USB Port.
