【Training Camp】EasyEDA Light-225480A

Project purpose:
This is the first project created by participating in the "EasyEDA & Tuya Smart Practical Training Camp". It is mainly to conduct preliminary imitation learning according to the content of the live class.

Basic functions:

* Realize WiFi and Bluetooth wireless control of RGB small lights.
* The color and brightness of the colored lights can be controlled through the Tuya Smart app.
* 5V microUSB port power supply.

Special functions:

* Compared with the live content of the training camp, it mainly adds an external J2 port, which leads to 8 ports that are not used by the WB3S module for later debugging;
* Adjusted the layout of the PCB board, which is relatively more compact;
* Added my own logo.

Failure record: Because it was the first time to use EasyEasy and the first time to solder SMD components, I failed many times, but fortunately I finally succeeded.

* First, the drawing board was made. The schematic diagram was drawn incorrectly at the beginning, and the LED power supply was connected incorrectly. After discovering it, I changed the schematic diagram, but **forgot to update the PCB**, resulting in an error in making the board. You can see a flying wire on the board.
* Secondly, **the LED was soldered in reverse**, and the LED was directly crushed when it was disassembled. Fortunately, I bought multiple LEDs. This Meihua MHPA3528RGBCT is too small and it is made of plastic. **You must be very careful when soldering**.
* The patch is too difficult to solder, it is twisted and crooked, **AO3400A was damaged** again, resulting in the wrong color at the beginning, so I had to replace it with a new one.
*

Tips:

* 1. Because it is the first time to use Tuya, no more functions are added, only 8 ports that are not used by the WB3S module are introduced.
* 2. There are two components in the BOM that actually need to be ordered, you can change them yourself.
* 3. The first version of PCB has been physically verified. The subsequent two versions of PCB were optimized and modified after referring to the review video, mainly for layout and routing, without board making, there should be no problem as long as the schematics are consistent.
