Jrk 21v3 USB Motor Controller with Feedback (乌克兰少妇xxxx做受 Soldered)
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 乌克兰少妇xxxx做受 installed as shown (no soldering required).
