Summary
The 40V servo was conceived to fulfill the purpose of a high-voltage tolerant high-torque small "smart" motor. It is intended to communicate over I2C, and is capable of position control, velocity control, torque control, and more.
Any motor can be used with this, since current is controlled by the H-bridge.
Design Notes
- R2 is the current limiting resistor. See schematic and datasheet on selecting resistor size.
