## Description

Adafruit's QT Py boards are a great way to make very small microcontroller projects that pack a ton of power - and now Adafruit have a way for you to quickly add a nice mechanical key that also can glow any color of the rainbow.

Adafruit call this the **Adafruit NeoKey BFF** - a "Best Friend Forever". When you were a kid you may have learned about the "buddy" system, well this product is kinda like that! A board that will watch your QT Py's back and give it more capabilities.

This PCB is designed to fit onto the back of any QT Py or Xiao board; it can be soldered into place or use pin and socket headers to make it removable. Onboard is a Kailh socket, which means you can plug in any MX-compatible switch instead of soldering it in. You may need a little glue to keep the switch in place: hot glue or a dot of epoxy worked fine for us. Also comes with a single reverse-mount NeoPixel pointing up through the spot where many switches would have an LED to shine through.

Adafruit include some header that you can solder to your QT Py. [You can also pick up an Itsy Bitsy short female header kit to make it removable but compact](https://core-electronics.com.au/short-female-header-kit-for-itsybitsy.html), you'll just need to trim down the headers to 7 pins long.

The key-switch is default connected to **A3** and the NeoPixel to **A2** but there are onboard jumpers you can cut to re-configure if you desire.

**QT Py is not included**.

**Please note,** **each order comes with one assembled PCB and break-off header**. A mechanical switch and key cap are not included! Use any MX-compatible switch: Kailh, Gateron, etc all work!
