1. 40PIN pin comparison diagram

The 40-Pin of the LubanCat-RK3588 series boards are not exactly the same, but they all have fixed common interfaces I2C, SPI, UART, and PWM. Their positions on the 40-pin are fixed, and the pin numbers and GPIO may be different, which need to be determined according to your actual needs.
