Product description
A89301 is a motor controller for controlling 3-phase brushless motors (BLDC, Brushless DC Motor). The board is based on the Allegro A89301 and uses external MOSFET transistors for high output power. The controller supports analog control, PWM, pulse frequency, and I²C. It can be configured via I²C using Pololu software. Supplied with pre-soldered pin headers and screw terminals.
