Onboard 32k crystal oscillator for more accurate clock timing

Comes with four buttons (one of which is connected to EN and another to IO0)

It can be directly inserted into the screen, and the screen purchase link (the price increased by 3 yuan after purchase, originally only cost 8 yuan more): https://item.taobao.com/item.htm?spm=a1z09.2.0.0.56bb2e8dDJQ5Gj&id=627825089608&_u =k2dklb45ccb5

Disadvantages: Due to control limitations, only two IO ports are available, and there are no other sensors on the board. The previous version had a temperature sensor but it was inaccurate due to chip heating.

The BOM table is for reference only except for parameters. You can choose the original with the same parameters by yourself.

 Also recommended is Teppanyaki, as hand welding is difficult.
