I2C bus cascader+MPU6050 gyroscope+WS2812 lamp bead expansion board

Overview

After connecting an MPU6050, a multi-channel interface can be expanded at the same time, which can be connected to WS2812 lamp beads.
PD5048A itself can be set to 8 addresses. Each PD5048A can be connected to 8 devices. In this way, an I2C bus can expand 64 devices with the same address. Two ESP32 Bus can be expanded to 128 device
