Originally, I wanted to make a smart photo frame, but the existing boards varied in shape and size, and installing the screen would require various wiring modifications. Therefore, I created this module with basic functions to simplify later production without needing to consider core wiring; I only needed to focus on developing a compatible baseboard for changing requirements.
Except for the WiFi pin, all other pins are expandable.
Features include an onboard wireless module, an onboard TF card pin, an onboard FLASH pin for SPI applications, an onboard serial chip with a Type-C interface for easy debugging, and an onboard USB pin for expanding USB interfaces using a USB expansion chip.
For PCB testing, it runs perfectly on the Lychee Pi system.
