Features:

LILYGO® LILY Pi ESP32 WIFI Bluetooth 3.5 inch capacitive touch screen 5V relay USB expansion port for Arduino

LILY Pi is designed and modified by the LILYGO team based on the Raspberry Pi appearance structure. The appearance is similar to the Raspberry Pi motherboard structure. The 2X20 expansion port next to it has reserved pins that match the Raspberry Pi GPIO, which is suitable for some Raspberry Pi Expansion function accessories.

LILYGO® LILY Pi ESP32 WIFI Bluetooth 3.5 inch capacitive touch screen 5V relay USB expansion port for Arduino

Based on this structure, a 3.5-inch capacitive touch screen expansion board is designed and made, which is suitable for use on Raspberry Pi.

Functionally based on ES32-WROVER (WIFI/Bluetooth) module, 5V relay, buttons, RTC, battery-powered interface, DC socket (5-12V input) battery-powered switch, USB expansion port I2C/UART, USB expansion port are designed The output power supply can supply power and control the current of equipment below 1A.

The back side retains the TF card socket in the same position as the Raspberry Pi, which is a self-popping card socket, which is convenient for plugging in and out.
