XiaoESP32-breakout-board

Breakout board for SeedStudio XIAO ESP32 for IOT and smart home applications.

Power input

There is 3 choices for powering the board:

  • USB
  • 3.7V Battery (charging with USB-C)
  • External power 2-6V (such as 2 to 4 AA or AAA batteries)

Usage

I2C Grove connector

There is 4 I2C grove connector. This is for I2C slaves such as Seeed Studio grove sensors or others. Note that these connectors are only intended for I2C communication only. The I2C communication is on a 5V bus.

SPI Screen connector

There is a connector for SPI communication. This connector has a Command/Data pin as well as BUSY and RESET pins for a screen. The Chip Select pin is always VCC or GND by a jumer. The SPI communication is on a 3.3V bus.

GPIO

There is 3 GPIO available on the board. 2 of them have a pull-up resistor to VCC for a switch input. The third GPIO has a MOSFET to the 5V power for high current output.

Developement

This project is under developement and can be modified
