Description
- Simple bidirectional control of one DC brush motor
- Operating supply range: 5V to 28V
- 3A maximum continuous current output (5 A peak)
- High-speed communication protocol
The Pololu Jrk 21v3 USB motor controller is a versatile, motor controller that supports interfaces, including USB. The continuous output current is approximately 3A in the recommended operating range of 8-28 V, with derated performance down to 5V and transient protection to 40V. Analog voltage and tachometer (frequency) feedback options allow quick implementation of closed-loop servo systems, and a free configuration utility.
Key improvements over competing products:
- USB connectivity with emulated serial (COM) port
- Ultrasonic PWM to eliminate switching-induced motor shaft hum or whine
- High internal resolution (12 bits) for smooth and flexible calibration to various input and feedback devices
- Current sensing and limiting
- Reversed power protection
- Field-upgradeable firmware
