M5STACK 4EncoderMotor Module - BL5617 - Motor Driver Module - for M5Core

The 4EncoderMotor Module is a 4-channel DC motor driver module from M5Stack. The motor voltage can be selected via a switch so that it is either 5V (max 10W total) or equal to the supply voltage. The module also contains an extra voltage converter that can power the M5Core. In addition, there are four Grove connectors to connect encoders, so you can make 4 so-called closed-loop motors. The module contains a microcontroller that controls the 4 motor drivers and reads out the current sensor and encoders. This microcontroller can then be read out and controlled via I2C.
