Weixue's same ESP8266 ink screen development board

We all know that among the many stores selling ink screens on Taobao, Weixue has the most complete information and relatively good after-sales service. But there is also a very big disadvantage: expensive (no, expensive should be my shortcoming

So I was smart and thought of a way to only get the prostitution information for free without buying anything. The selling price of this board Weixue is RMB 67, which can be said to be very high, so I spent a day replicating it as completely as possible, which is this project.

Compared with the original version of Weixue, a lot of things have been added, such as:

1. The interface has been changed from MicroUSB to the extremely advanced Type-C, which avoids the embarrassment of looking for cables everywhere during debugging;
2. Connect GPIO16 of ESP8266 to RST, so that ESP8266 can enter DeepSleep mode;
3. You can freely switch between 0.47R and 3R and between 3-wire spi and 4-wire spi modes, which is suitable for more ink screens;
4. The package adopts 0603, which is easier to weld;
5. An ESD diode is added to the USB to prevent static electricity from damaging the USB in winter.
