Here's a simple guide to get your Pocket Scíon up to date and running the latest firmware.

1 - Download the latest firmware here
instruomodular.com/firmware

2 - Connect one end of a compatible USB cable to your computer (Don't connect the Pocket Scíon yet)

3 - Press and hold the button on the inside of the Pocket Scíon (see video for exact location)

4 - While still holding the button, connect the USB cable to the Pocket Scíon
The Pocket Scíon will now appear as a mass storage device on your computer named "RPI-RP2"

5 - Drag the downloaded uf2 firmware file to "RPI-RP2"

6 - Do not disconnect

7 - Wait for 3ish minutes until the Pocket Scíon reboots (Perhaps have a cup of tea)

Hoorah! You are up to date.
