This expansion board is designed for the Raspberry Pi, no need for an external cable, the Raspberry Pi board can insert directly. It equipped with PCA9685 chip, RGB colorful lights, buzzer, GPIO lights, and other common hardware resources. Onboard 6-way servo interface, 2 way DC motor interface and various module interfaces to expand by yourself. The biggest difference of this expansion board is that it includes a speaker interface and an audio interface, so it can realize the function of voice broadcast. In addition, we also design various protection circuits on it and two different power supply interfaces, T-type and DC3.5. In conclusion, this expansion board will be the best experimental partner for your Raspberry Pi board in robotics experiments.

Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
