The Easer 25 is a small but powerful motor driver/controller that is user-friendly and equipped with many innovative features. With its current sensing travel limits, there's no need to install limit switches and long wires, making it a convenient solution. Soft start/stop smoothens the motor's operation and enhances overall system efficiency. The controller is versatile, accepting a variety of modes such as Radio Control PPM, standard PWM/DIR, one wire PWM 50/50, standard Analog/DIR, pot-based joystick analog (bi-directional), and more.
