To give a brief introduction, this driver board is mainly suitable for various ink screens of WeiXue. The STM32 sample program on the WeiXue website can be used directly.

Normally, you only need to weld a 0 ohm resistor to ground at the BS end.
Everyone knows the rest. This thing is made to facilitate testing the price tag screen for salted fish purchases.
Of course, he can also play with lighting, plug in DS18B20 or DHT11 to measure temperature and humidity, and can also drive ordinary displays of IIC or SPI.
Friends who like it, welcome to collect and like it:)
There is also an ESP8266 WeiXue driver board, which is much smaller than this board, but it doesn’t feel as clear as the STM32.
Those who are interested can go and take a look.
