Jrk G2 21v3 USB Motor Controller with Feedback Pololu

DESCRIPTION

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, analogue voltage (potentiometer), and hobby radio control (RC).

This version offers a 4.5V to 28V operating range and can deliver continuous output currents up to 2.6A (5A peak) without a heat sink. Male headers and terminal blocks are included but not soldered, allowing for custom installations.

Please Note:

• This Motor Controller comes with header pins and terminal blocks included but not soldered, so soldering is required to use it.

FEATURES

• Easy open-loop or closed-loop control of one brushed DC motor
• A variety of control interfaces:
  • USB for direct connection to a computer
  • TTL serial operating at 5 V for use with a microcontroller
  • I²C for use with a microcontroller
  • RC hobby servo pulses for use in an RC system
  • Analogue voltage for use with a potentiometer or analogue joystick
• Feedback options:
  • Analogue voltage (0 V to 5 V), for making a closed-loop servo system
  • Frequency, for closed-loop speed control using pulse counting (for higher-frequency feedback) or pulse timing (for lower-frequency feedback)
  • None, for open-loop speed control
  • Note: the Jrk does not support using quadrature encoders for position control
• Ultrasonic 20 kHz PWM for quieter operation (can be configured to use 5 kHz instead)
• Simple configuration and calibration over USB with free configuration software utility (for Windows, Linux, and macOS)
• Configurable parameters include:
  • PID period and PID coefficients (feedback tuning parameters)
  • Maximum current
  • Maximum duty cycle
  • Maximum acceleration and deceleration
  • Error response
  • Input calibration (learning) for analogue and RC control
• Optional CRC error detection eliminates communication errors caused by noise or software faults
• Reversed-power protection
• Field-upgradeable firmware
• Optional feedback potentiometer disconnect detection
