CircuitPython on Circuit Playground Bluefruit
Install or Update CircuitPython
Follow this quick step-by-step to install or update CircuitPython on your Circuit Playground Bluefruit.
https://adafru.it/FNK
Click the link above and download the latest UF2 file
Download and save it to your Desktop (or wherever is handy)
Plug your Circuit Playground Bluefruit into your computer
using a known-good data-capable USB cable.
A lot of people end up using charge-only USB cables and it
is very frustrating! So make sure you have a USB cable you
know is good for data sync.
Double-click the small Reset button in the middle of the CPB
(indicated by the red arrow in the image). The ten NeoPixel
LEDs will all turn red, and then will all turn green. If they turn
all red and stay red, check the USB cable, try another USB
port, etc. The little red LED next to the USB connector will
pulse red - this is ok!
If double-clicking doesn't work the first time, try again.
Sometimes it can take a few tries to get the rhythm right!
(If double-clicking doesn't do it, try a single-click!)

You will see a new disk drive appear called CPLAYBTBOOT.
Drag the adafruit_circuitpython_etc.uf2 file to
CPLAYBTBOOT.
The LEDs will turn red. Then, the CPLAYBTBOOT drive will
disappear and a new disk drive called CIRCUITPY will
appear.
That's it, you're done! :)
