I2C Motor Drive Board 4-Channel Servo Motor Driving Module with Straight Pin Header for 4WD Mecanum Wheel Chassis
Description:
- This four channel motor drive module adopts a stacked design and can be directly plugged into the motor drive module on the main control board for Arduino UNO or its compatible board. It integrates PCA9685 chip (a 16 channel PWM controller controlled by I2C bus) and 4xRZ7889 motor driver chips, which only occupy the IIC port for Arduino (A4 SDA/A5-SCL) to control 4 channel motors, with IIC address of 0x40. It can directly connect 4 motors (M1, M2, M3, M4) interface sequence: motor positive pole, motor negative pole, encoder negative pole, encoder positive pole, phase A, phase B; Compatible with multiple motors in our store: TT motors N20, GA25-370, GB37-520, GB37-3530; And expand 4 IIC interfaces, 1 GVTR serial communication interface, 6 GVS standard sensor interfaces, and 5 servo interfaces.
Function and Advantages:
- Motor interface: 4-channel motor interface, can be connected to 6-wire encoder motor or 2-wire DC motor. (requires external power supply)
- Servo interface: 5-channel servo interface, can connect to standard servos such as MG996R and SG90. An external power supply of 5-7V is required, and can be used with a 6V battery pack, switch mode power supply, and voltage reduction/stabilization module. Connect two or less 9g servos can use onboard 5V power supply.
- Servo + motor interface: It can control both the servo and motor simultaneously, both of which require separate power supply. The servo recommends a 6V battery pack, switch mode power supply, etc. The motor is uses 6-12V power supply.
- Sensor module: 1 UART serial port, 4 IIC interfaces, and 6 sensor IO ports
- Stacking design: can be directly stacked with the motherboards for UNO R3 and Mega2560 without the need for separate wiring.
