Module 4EncoderMotor
Description
4EncoderMotor Module is a 4-channel encoder motor driver module that utilizes the STM32+BL5617 solution. It is suitable for various applications such as robot motion control, automation equipment, smart vehicles, laboratory equipment, and industrial automation systems.
4EncoderMotor Module supports multiple control modes, including duty cycle control, absolute position positioning, and speed adjustment. Users can easily implement functions such as forward rotation, reverse rotation, stop, and braking for the motors. This module adopts I2C communication and allows for the modification of the slave address, providing flexible control options. With the input of AB pulse encoder signals, it can accurately detect the motor's motion state and position.
To ensure the stability and safety of the motor system, the module also integrates the INA199 power monitoring, which continuously monitors the voltage and current status in real-time, ensuring that the motor operates within the appropriate power range. Additionally, the 4EncoderMotor Module features an onboard power input switch. Users can choose between DC 5V or external DC 6-12V power input to meet the requirements of different application scenarios.
