[3DMakerWorld] Pololu Jrk G2 21v3 USB Motor Controller with Feedback (Assembled)

Description

Key Features:
Easy open-loop or closed-loop control of one brushed DC motor with pre-soldered connections
Supports five control interfaces: USB, TTL serial, I2C, analog voltage (potentiometer), and hobby radio control (RC)
Free configuration software utility for Windows, Linux, and macOS
Ultrasonic 20 kHz PWM for quieter operation (can be configured to use 5 kHz instead)
Optional CRC error detection eliminates communication errors caused by noise or software faults
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.
