High-Power Simple Motor Controller G2 18v25
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 25 A without a heat sink. Male headers and terminal blocks are included but not soldered, allowing for custom installations.

Notes:
- 1
- Without included hardware.
- 2
- Autodetects baud rates between 1200 and 500,000 bps, or can be set to any fixed baud rate in this range.
- 3
- Absolute maximum; higher voltages can permanently destroy the motor driver. Recommended maximum is approximately 24 V, which leaves a safety margin for ripple voltage on the supply line. Not recommended for use with 24V batteries.
- 4
- Typical results at room temperature running at 90% duty cycle.
- 5
- All digital inputs are 5V tolerant.
