ESP32 Desktop Rubik's Cube (Circuit Only)

The overall size is 28 x 39 cm, the same as the 1.3-inch TFT screen I'm using. The final product thickness is 1.7 cm, and the screw holes are M2.
After testing, the screen works normally, can run lvgl, and uses the eSPI library. The MU-UP6050 and SHT20 can also be used normally
, but there is a problem with TF card read/write. After searching online, the problem was finally narrowed down to the power supply. I will make a PCB to confirm when I have time.
The final product is as follows:

1. Component layout
2. SHT20 is too expensive, it can be replaced with TI's HDC1080DMBR
3. The screen can be a touch screen
4. Power indicator light
5. No battery voltage detection
6. Larger three-position dial button, this one is too small and the feel is not good
7. A nice-looking shell
I will modify it one by one when I have time. I hope it is not a series of "lifetime dream"

if I want to replicate it. If I want to replicate it, the soldering order is:
1. Solder the Type-C first
2. Power supply system
3. Automatic download circuit and ESP32
4. MPU6050 (hot air gun)
5. SHT20 (hot air gun)
Testing step by step is essential to ensure the quality of the final product.
