Serial ink screen universal driver board

Overview

This is a universal driver board for serial ink screens. It can drive almost all serial ink screens. It has two slots, 24p/34p. Of course, they can only support 24p ink screens. The 34p socket is used to arrange cables. For relatively wide screens, such as Laowang's 1.54 three-color screen and Hanshow's 2.13 price tag screen, there is no need to cut the cable.

This driver board supports 0.47/3R resistance switching and supports more types of screens.
Supports switching between 4-wire and 3-wire SPI.
It supports 5V and 3V3 level microcontrollers, which can be switched through the DIP switch (you can also not solder the level conversion chip and LDO, and the DIP switch flying wires. Theoretically, the driver is fine, but it is not clear what will happen over time. Please Choose carefully), it is 3V3 level when it is turned on, and it is 5V level when it is turned off.

Self-provided power supply management needs to be standardized
At present, the contradiction between power supply and demand is very prominent. In order to ensure the completion of production tasks and meet their own electricity needs, the majority of power custo
How to fix it? What are the problems encountered when 430ADC opens internal and external channels at the same time?
[backcolor=white]Has anyone played with the AD of 430F5418, whose input channels are external ADC12INCH_0 and internal ADC12INCH_10. Because the channel numbers are not continuous, will there be probl
