Submission of the work "Mijia Control 16-way Relay Switch Based on GigaDevice GD32" [Copy link]

• Brief introduction

This DIY mainly uses the GD32 microcontroller to control the normally open and normally closed switching of 16 physical buttons and the corresponding 16 relays. At the same time, GD32 completes data exchange, protocol analysis, event reporting, etc. with the Xiaomi wireless module, making full use of Xiaomi's cloud platform and Mijia and other IoT platforms to achieve smart home control.

• Video demonstration

After nearly two months of hard work, the prototype of this DIY product is finally available. Let's take a look at the video demonstration first, and then add relevant content later.

Shouldn't we use 350? 103 doesn't count, right?
