# servo-control-board
22
Breakout PCB for connecting external stepper/servo motor drivers.

4-
- Takes digital pins from the Archimajor board and shifts voltage according to input using power drivers. 0-50V
4+
- Takes digital pins from the Archimajor board (3.3V) and shifts voltage (0-50V) according to input using power drivers.
5+
- Maximum of 11 motors: 7 external, 4 TMC5160
56
- Display reads out supplied voltage for redundency.
67
- Pinout is simple and single-ended. Assuming motor driver takes step/pulse, direction, and enable. Currently no support for HLFB.
8+
- Extra +5V and +3.3V output pins
9+
- The main purpose of the project is to drive external servo motors, but other digital I/O devices can be used.

- NOTE:
21+
- The step/dir header on the archimajor are used for the last four stepper drivers.
22+
- These pins can be reassigned for external motors on the breakout board.
23+
- You cannot simultaneously drive an external motor and use the embedded drivers.
