[Verified]CH32V003F4P6 development board backplane V1.1

Overview

In the BOM table of a development board designed using CH32V003,

except for the core board and pin headers, all the mall components have been matched. You can directly delete the components based on the ones you have on hand and place an order.
The core board link is https://oshwhub.com/ 0x49181f36/ch32v003f4p6-hu-xin-ban-v1-1
can learn 74HC595 8-bit serial input and parallel output displacement register (verified)
digital tube running light (verified)
serial port communication (verified)
PWM wave (verified ) Verified)
ADC (verified)
TM1650 IIC communication matrix keyboard (verified)
SSD1306 IIC screen
ST7735 SPI screen can be DMA (verified)
WS2812 Phantom TIM method can be DMA (verified)
