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.
