Jrk G2 21v3 USB Motor Controller with Feedback (Connectors Soldered)
This compact motor controller makes closed-loop speed or position (but not both!) control of a brushed DC motor easy, with quick configuration over USB using our free software. It supports five control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), and hobby radio control (RC). This version offers a 4.5 V to 28 V operating range and can deliver continuous output currents up to 2.6 A (5 A peak) without a heat sink. This version ships with soldered header pins and terminal blocks.

Notes:
- 1
- Powering the Jrk G2 21v3 with a supply voltage between 4.5 V and 5.5 V might cause its logic voltage to be lower than normal, which could affect operation. See the user’s guide for more information.
- 2
- Transient operation (< 500 ms) up to 40 V.
- 3
- Typical results at room temperature running at 90% duty cycle with VIN > 8 V. Operation from 4.5 V to 8 V reduces maximum current output.
