## Description
|
||
|
||
**DC MOTOR** is built with MEGA328 and L293DD microcontrollers, implemented 4 driver channels. A DC power input is designed for power supplement. Through M-BUS the DC in can automatically power the M5 core at top. DC motor module can drive RJ12 interface encoder-motor easily and quickly, such as LEGO ev3 Motor.（This product is not affiliated with or endorsed by LEGO.
