SPC Low Cost Motor Controller is a DC/Stepper Motor controller for 4 DC motor or 2 stepper motor which has been equipped with driver motor so can be connected to the DC/Stepper motor directly. Control the direction and speed of 4 DC motor uses PWM methode and control the direction and speed of stepper motor uses full step & half step. This module has been equipped with UART TTL and I2C interface to communicate with another device.

Dimension : 6,5 cm (L) x 4,1 cm (W) x 1,7 cm (H)
