Stm32 NUCLEO series core board is very comprehensive, but the only exception is that it does not have a dedicated LCD screen. In the spare time, an exclusive touch XPT2046 ( XPT2046 data sheet ) LCD module is provided for the STM32 NUCLEO series core board. EPROM AT24C02 ( AT24C02 data sheet ) , TF card slot.
In order not to affect normal use, the pins are compared to the STM32 NUCLEO series schematics andPcbfinds no occupied pin, so that no jumper can be modified to test, and in order not to affect the normal pin jumper, the LCD module is used as the backplane, and the STM32 Nucleo system core board is inserted on it for convenience. use!
