M5Stack GoPlus2 STM32F0 DC Motor & Servo Driver Module w/ Battery

The module can be powered by its built-in 500mAh battery for portable use. For high-current scenarios or simultaneous motor/servo operation, connect an external DC power supply to the dedicated input jack. To charge the internal battery, stack the GoPlus2 onto an M5Stack Core (like Core2) and connect the Core's USB-C port to a 5V source. The Core manages the charging process. Ensure external power is disconnected when charging via USB.

Connect your DC motor to one of the two motor ports using the included cables. In your Arduino IDE sketch with the M5Stack library, include the "M5GoPlus2.h" header. Initialize the object, then use functions like `GoPlus2.Motor.write(0, speed)` where '0' is the motor port (0 or 1) and 'speed' is a value from -100 (full reverse) to +100 (full forward). The HR8833 driver handles the H-bridge switching. Remember to set up the external power or ensure the battery is sufficiently charged for high torque demands.

Yes, the four servo outputs provide standard 50Hz PWM signals compatible with most 3-wire RC servos (power, ground, signal). Connect your servo, ensuring the voltage matches your power source (battery or external DC). In code, use the library's servo control functions, such as `GoPlus2.Servo.write(port_number, angle)`, where the angle is typically between 0 and 180 degrees. The STM32's hardware timers generate stable pulses. Avoid drawing excessive current from multiple servos simultaneously without adequate external power.
