Introduction
The multifunctional motor driver expansion board is designed for Raspberry Pi Zero/Zero W/A+/B+/2B/3B/3B+/4B. This fully-featured robot motor expansion board is capable of supporting multiple motors,
stepper motors, and servos simultaneously.
It also provides spare camera and DIP display screen ribbon interfaces and can be used in stack layers to expand more control interfaces.
The control interface uses a simple I2C interface,
compatible with 3.3V/5V levels, and also includes a UART interface for
easy communication with external devices.
Additionally, it features a built-in DC-DC voltage stabilizing circuit, ensuring a stable power supply for Raspberry Pi
with a current reach of up to 3A.
This expansion board is particularly suitable for applications such as DIY robots, smart cars, robotic arms, intelligent cloud decks, and more.
