Description The M5Stack 4EncoderMotor v1.1 is a 4-channel encoder motor driver module based on an STM32F030C8T6 MCU and BL5617 H-bridge driver ICs. It uses I2C communication and supports slave address adjustment, giving M5Stack controllers a compact way to control multiple DC or encoder motors. Through AB pulse encoder signal input, the module can detect motor motion state and position for duty-cycle control, absolute positioning, and speed adjustment. It also integrates INA199 current detection for real-time current monitoring and supports either onboard DC 5 V input or external DC 6-12 V power input for motor driving. Notes Interface change: Compared with the previous 4EncoderMotor module, v1.1 uses a unified HY2.0-6P interface for encoder motor connections. Features 4-channel encoder motor driver for DC motors and encoder motors. AB pulse signal input for motor motion state and position detection. Duty-cycle, absolute position, and speed adjustment control modes. I2C communication at address 0x24 with adjustable slave address support. Motor voltage input and INA199 current monitoring. Supports forward rotation, reverse rotation, stop, and braking control. External DC 6-12 V motor power input with onboard power input switching.
