Tmall Elf’s multi-hole sub-controlled smart power strip

### Project Introduction I have always wanted to make a multi-hole sub-control strip. I have been thinking about it for a long time, and finally took some time to do it. Currently, this board is drawn using AD, and the ESP32-C3 used for the chip is developed based on ESP-IDF. program. At present, there are serious problems with both hardware and software. The later preparation is to use Lichuang eda to draw the second version. The main reasons will be listed below... - - - ### Project function introduction* Belt There is a single-phase electricity measurement chip, which can later be expanded with multiple functions, including electricity billing, real-time power, etc. * It is more difficult for me to write the code of Tmall Genie using Bluetooth BLE-MESH. At present, I can basically control the multi-hole branch control and plug-in. I will write an article and open source it after I learn the later protocol. * Since esp32-c3 is used, with wifi and ble, you can also use wifi to connect to various cloud platforms. The mqtt and json control of wifi is relatively simple. * Comes with matching 3D shell files for easy design of customized shells. - - - ### Project Properties Here you can fill in the completion progress bar of the project, select the check box according to the completed function, or display it as the completion progress of the function* [x] Schematic design* [x] PCB Drawing design* [x] PCB proofing* [x] Welding test* [x] Functional test* [x] Program test- - - ### No circuit explanation yet - - - ### Software No software yet - - - ### The picture is at the bottom. - - - ### See the attachment for the demonstration video. There are only the simplest usage videos, there are many questions, just for testing. - - - ### Notes There are still many problems at present. If you need to use it, you can communicate in the comment area. It will be updated later when the routine is corrected. I've been really bored with the final exam recently, so I'll revise it whenever I have time. - - -

Due to the hardware circuit problem of the board, I can only use the minimum system jumper to debug, which will be improved in the second version later.
