1. Introduction
The ESP32 S3 (expansion board) is a้ ๅฅ expansion board designed based on the development board EPS32-S3, integrating the pins of the development board onto a PCB circuit board.This expansion board is compatible with all EPS32-S3 series development boards.The circuit board is equipped with a PH2.0 interface while also retaining pin headers to meet the different wiring needs of users.
2, Characteristics
1, There are digital IO pin headers (pin numbers: 0-16, 21) and analog IO pin headers (pin numbers: 38-42, 45-46). (This can meet the need for connecting extension modules with Dupont wires)
2, there are digital IO ports PH2.0 3P sockets (pin numbers: 2, 4, 12, 13, 14, 15) and analog IO ports PH2.0 3P sockets (pin numbers: 32, 33, 34, 35, 36, 39), as well as 4 PH2.0 4P sockets, 2 PH2.0 5P sockets, and 1 PH2.0 6P socket.
3, featuring SPI communication interface pins, serial communication interface pins, I2C communication interface pins.
3, Expansion Board Parsing
Digital IO port PH2.0 3P socket (2, 4, 12, 13, 14, 15) and digital IO port pin header (0, 2, 4, 12, 13, 14, 15, 1, 17, 25, 26, 27)
You can specify these IO ports as digital outputs, which means they can output high or low levels.
Simulated IO port PH2.0 3P socket (32, 33, 34, 35, 36, 39) and simulated IO port pin header (32, 33, 34, 35, 36, 39)
Can specify these IO ports for simulation input and simulation input.
