Hi38661 Hongmeng wifi switch +904291S

Overview

Use the Hongmeng Hi3861 chip combined with the servo to implement physical switches, [HDR-M-2.54_1x9](https://lceda.cn/component/24e45360a75d4413b40d4dad1a13508a) and [HDR-M-2.54_1x](https://lceda.cn/ component/24e45360a75d4413b40d4dad1a13508a)5 You don’t have to buy it. Anyway, there are many 1x10s, and the cost is about 51 yuan. I only used 4 pins. After burning, I unplugged them to connect the servo, which saved money.
