If use it in other operating environment, please adjust the usage according to the schematics. 3.1 Digital ports This IO expansion shield provides 12 groups of digital ports including 0~13 except 4 and 8, which can be used directly by IO number. Note: When ESP32 uses pins in the Arduino environment, you need to use Dx such as D0 instead of directly using IO number 0, or use IO number corresponding to the mainboard. 3.2 Analog ports This IO expansion shield provides 5 groups of analog ports including A0~A4, which can be used directly by IO number. 3.3 I2C ports This shield provides 3 groups of I2C ports in parallel. 3.4 UART ports This shield provides 1 group of UART ports. R corresponds to pin 0, T to pin 1. When using UART, please do not use pin 0 and pin 1. 3.5 SPI ports Thi hi ld id 1 f SPI t i t SD d d l i li d SS i This shield provides 1 group of SPI ports, supporing to use SD card module in-line, and SS is connected to pin 6. 3.6 SP pin The SP pin presents different functions on different mainboards, representing NC, RXD, TXD, A5 on M0, and I2C on ESP32-E. 3.7 GDI display interface This interface is a DFRobot dedicated GDI, with 18pin-FPC cable connection and single wire connection to the screen, providing you with the simplest way to use the screen.

The GDI on the expansion shield only supports ESP32-E. If you need to use GDI for M0, please use the GDI integrated on the development board. Power socket and EN switch VIN: Connect to the VCC pin on the mainboard. The terminal is convenient for connecting the spiral battery. Note: When VIN is connected to an external power supply, do not connect the main control to other power supply or USB. GND: Common ground EN: It can be designed as the maincontroller switch. When EN is grounded, the main controller will stop running.
