【Training Camp】Bricks who can run

Overview

The Hi3861 module is developed based on the OpenHarmony open source Hongmeng system. It drives 8 servos through the PCA9685 servo drive chip to drive joint movement and realize various movements. The power supply is powered by dual lithium, and the charging adopts TP5100 from the open source square's Xiaoxin team. As the core dual-cell lithium battery balance charging module, the MPU6050 module purchased from Taobao serves as the attitude sensor.

I don’t know what kind of painting the outer shell should be, so I painted it and painted it into bricks.

PCA9685 is out of stock at Lichuang. I bought LU9685 from Taobao. The PCB was repainted and the board was also reprinted.
