The 180 optical encoder motor is equipped with an optical encoder that enables high-accuracy control. With two M4 threaded holes on each of the three sides, it can be easily connected to Makeblock mechanical parts and thus can be used flexibly in combination with various other parts. The customized material it uses reduces noise and promises large output torque. It supports multiple motor drivers and main control boards, such as Orion, MegaPi, MegaPi Pro, Me Auriga, and mBot2 Shield.
