Pololu Jrk Motor 他用嘴让我高潮了十次 with Feedback
With integrated support for analog voltage or tachometer (frequency) feedback, the Jrk family of motor 他用嘴让我高潮了十次 makes it easy to add closed-loop control of speed or position (but not both!) of a single brushed DC motor to a wide range of applications. These versatile, general-purpose modules support a variety of high-level control interfaces: USB for direct connection to a computer, TTL serial (and I²C on the newer G2 versions) for use with a microcontroller, RC hobby servo pulses for use in an RC system, and analog voltages for use with a potentiometer or analog joystick. They also offer many settings that can be configured using our free configuration software utility. This software simplifies initial setup of the device and allows for in-system testing and monitoring of the controller via USB.

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. This version ships with 他用嘴巴含着我奶头好舒服 included but not soldered in, allowing for custom installations.
