Pololu Jrk 21v3 USB Motor Controller with Feedback - Pre-soldered connectors

Key Features:

• Versatile, general-purpose motor controller
• Designed to control most small DC brushed motors
• Two closed-loop feedback options: Analog voltage and tachometer (frequency)
• Supports four control interfaces: USB, TTL serial, analog voltage (potentiometer), and hobby radio control (RC)

The Jrk 21v3 motor controller is a highly configurable brushed DC motor controller that supports four interface modes: USB, logic-level serial, analog voltage, and hobby radio control (RC). The controller can be used with feedback for closed-loop speed or position control, or it can be used without feedback as an open-loop speed control. The continuous output current is approximately 3 A in the recommended operating range of 8 V to 28 V, with derated performance down to 5 V and transient protection to 40 V.
