【Training Camp】Muyun Electronic Dog

Overview

Create a dog as a platform for subsequent advanced expansion.

An 8-axis mechanical dog is built using Huawei WiFi chip HI3861 (WiFi module). With this, you can quickly use the famous Huawei Hongmeng system platform.

The servo MG90 uses a PCA9685PW chip driver with up to 16 PWM drives. Since the servo does not have high requirements for PWM frequency, you can also use the 8 IO ports of HI3861 to simulate PWM output to reduce circuit costs.

The power supply is powered by the power bank circuit SP4522B. A single 3.7V lithium battery can output 5V2A power supply to drive 8 sets of MG90 servos. In addition, it has a conversion efficiency of up to 95%, which greatly improves the battery usage efficiency. Reduce circuit heating. It can also be charged or powered by USB, which is very convenient to use.
