A servo driver with battery backup to ensure failsafe.
- Programming and debug over USB or I2C
- Passively switches to battery when supply is interrupted
- Detects when on battery and positions servo at configured safe state
- Debug LEDs
These voltages are dependent on what servo is being driven. They should not only be very close to one another, but also must be within the range of 5-12v.
Current should not exceed roughly 3 amps continous, probably can handle up to 8 amps burst (10 sec).

Servo signal and power
| LED | Description |
|---|---|
| Orange (ONBATT) | Indicates external supply is not present or insufficient and the backup battery is now supplying power. This will also trigger moving the servo to the configured safe state. |
| Red (REGERR) | Indicates the LDO regulator for the microcontroller is unable to maintain output (check battery or supply voltage). |
| Green (PWR) | Directly connected to internal 3v3 rail. Basically the opposite of REGERR. |
