Product description: H-bridge Unit v1.1 - motor controller with current measurement - STM32F030 - Unit expansion module - M5Stack U160-V11
H-bridge Unit version v1.1 is a module in the form of a Unit extension that can be used with M5Stack development boards. It is equipped with two efficient systems - STM32F030 and RZ7899 , which enable bidirectional control of the DC motor . The user can also obtain precise control over the engine operation by controlling the PWM signal.
Before you start working with H-bridge Unit v1.1, also check the user guide prepared by the manufacturer!
H-bridge Unit v1.1 - motor controller with current measurement - STM32F030 - Unit expansion module - M5Stack U160-V11.
Enables control of a DC motor.
Characteristic features of the module
- Compatible with development modules such as M5Stack Core Basic, M5Stack Fire and M5Stack Core2
- It has a built-in STM32F030 serving as an I/O system with I2C communication
- Enables control of a DC motor
- Measures the current consumed by the motor
- It has protection against overload, overheating and overvoltage of the motors
- It uses the I2C bus to communicate with connected modules
- It allows you to control the motor using a PWM signal
- It has the function of changing the direction of rotation and braking the motor
- It can be programmed using the UIFlow and Arduino platforms
Suggested use of the module
- Industrial automation
- Smart Home integration and expansion
- Mobile robots
- Prototypes of production lines
An electrolytic capacitor connected to the positive and negative poles of the power input can provide buffer protection for the circuit. Be careful not to connect the capacitor in the opposite direction.
