# Supported Hardware

Pretty much any nrf52840 that you can load an arduino sketch onto. E.g.

* [SEEED XIA0 nrf52840](https://shop.pimoroni.com/products/seeed-xiao-ble-nrf52840-supports-arduino-micropython-bluetooth5-0-with-onboard-antenna). Super small - will take a lipo if you solder onto the back batt pins
* [Adafruit nrf52840 express](https://shop.pimoroni.com/products/adafruit-feather-nrf52840-express). A great develeopment board. Has a spare button for you to use as either a pairing button or sending button.
* [Adafruit itsybitsy nrf52840](https://shop.pimoroni.com/products/adafruit-itsybitsy-nrf52840-express-bluetooth-le). Same as the feather - but smaller and slight less flashy

And for the dongle

* This is nice as its all in one piece. [nrf52840 USB key](https://thepihut.com/products/nrf52840-usb-key-with-tinyuf2-bootloader-bluetooth-low-energy-mdbt50q-rx)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.acecentre.org.uk/products/open-wireless-switch-ows/supported-hardware.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
