The back of the Apollo MSR-1 has exposed GPIO for a variety of uses.
From left to right:
- SLC (Typo, should be SCL)
- Used for I2C
- IO 5
- GPIO 5 of ESP32-C3-Mini
- 5V
- Used for powering the device, or powering a external sensor
- GND
- Ground
- 3V3
- Used to power external sensors. Can not power the MSR-1 from this
