High-Power Simple Motor Controller G2 18v15

This powerful motor controller makes basic 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 wide 6.5 V to 30 V operating range and can deliver continuous output currents up to 15 A without a heat sink. Male headers and terminal blocks are included but not soldered, allowing for custom installations.

The SMC G2 18v15 operates from 6.5 V to 30 V and can deliver a continuous output current of 15 A without a heat sink. Note that 30 V is the absolute maximum for this controller; the maximum recommended operating voltage is 24 V, and the maximum recommended nominal battery voltage is 18 V.

Note: A USB A to Micro-B cable (not included) is required to connect this controller to a computer.

Key features of the SMC G2 family

• Simple bidirectional control of one brushed DC motor
• Five communication or control options:
  1. USB interface for direct connection to a PC
  2. Logic-level (TTL) serial interface for use with a microcontroller
  3. I²C interface for use with a microcontroller
  4. Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller
  5. 0 V to 3.3 V analog voltage interface for direct connection to potentiometers and analog joysticks
• Simple configuration and calibration over USB with a free configuration program for Windows
• Reverse-voltage protection
• Hardware current limiting with a configurable threshold
• Current sensing

Additional features of the SMC G2 family

• Adjustable maximum acceleration and deceleration to limit electrical and mechanical stress on the system
• Adjustable starting speed and maximum speed
• Option to brake or coast when speed is zero
• Optional safety controls to avoid unexpectedly powering the motor
• Input calibration (learning) and adjustable scaling degree for analog and RC signals
• Under-voltage shutoff with hysteresis for use with batteries vulnerable to over-discharging (e.g. LiPo cells)
• Adjustable over-temperature threshold and response
• Adjustable PWM frequency from 1.13 kHz to 22.5 kHz (maximum frequency is ultrasonic, eliminating switching-induced audible motor shaft vibration)
• Error LED linked to a digital ERR output, and connecting the error outputs of multiple controllers together optionally causes all connected controllers to shut down when any one of them experiences an error
• Field-upgradeable firmware
