A small Bluetooth board with Bluetooth peripheral components for only 8 cents
A minimal system made.
The crystal inductor has to be removed from the original board. I have the capacitor myself and I am too lazy to remove it.
There is gitee SDK open source
It is best to download through the git command
git clone --recursive https://gitee.com/SydtekInc/SYD8811SDK.git
It is a relatively cheap Bluetooth board that can be developed. It is not a loss to remove the component chips for 8 cents each. The SYD8810 chip costs 4 pieces. You can also use the original board to write your own program to control the motor.
