**X-BOARD XIAO** is an expansion board designed to bring compatibility to [**Seeed Studio**](https://www.seeedstudio.com/)’s [**XIAO**](https://www.seeedstudio.com/xiao-series-page) development boards and It’s [**Grove**](https://wiki.seeedstudio.com/Grove_System/) ecosystem with **X-NODE**’s or [**Click Boards™**](https://www.mikroe.com/click-boards), allowing swift evaluation of sensors, actuators or communication modules. Ideal for prototyping and building electronic projects in an easy, compact and highly extendable fashion with other popular development standards like [**Grove**](https://wiki.seeedstudio.com/Grove_System/), [**mikroBUS™**](https://www.mikroe.com/mikrobus) and [**Qwiic®**](https://www.sparkfun.com/qwiic). It carries a single socket for [**XIAO**](https://www.seeedstudio.com/xiao-series-page)’s development boards, two JST connectors, three [**mikroBUS™**](https://www.mikroe.com/mikrobus) sockets and one single row 40 female pin header.

## I. How does it work?

**X-BOARD XIAO** allows ease of communication between [**Seeed Studio**](https://www.seeedstudio.com/)’s [**XIAO**](https://www.seeedstudio.com/xiao-series-page) development boards with X-NODE’s or [**Click Boards™**](https://www.mikroe.com/click-boards), or any other development tool that integrates [**mikroBUS™**](https://www.mikroe.com/mikrobus) pinout standard, just insert the board into one the available sockets.  It has two JST connectors compatible with [**Qwiic®**](https://www.sparkfun.com/qwiic) standard, be aware that the logic level is 3.3V, it also features 4 connectors compatible with [**Grove**](https://wiki.seeedstudio.com/Grove_System/) ecosystem making it compatible with a wide variety of development modules by [**Seeed Studio**](https://www.seeedstudio.com/). Finally, it features a single row 40 pin female header to access every single one the pins of any socket, this allows an easy access to all signal for analyzing, debugging, and testing.

**X-BOARD XIAO** is compatible with [**XIAO**](https://www.seeedstudio.com/xiao-series-page) and [**Grove**](https://wiki.seeedstudio.com/Grove_System/) standards from [**Seeed Studio**](https://www.seeedstudio.com/), [**Mikroe®**](https://www.mikroe.com/)’s [**mikroBUS™**](https://www.mikroe.com/mikrobus) and [**SparkFun®**](https://www.sparkfun.com/)’s [**Qwiic®**](https://www.sparkfun.com/qwiic), enabling ease of integration between multiple modules and development boards.
