#

if it is just copy the uf2 and assume it's good I can just proceed?

#

for some reason I just wanted to confirm it was good and on the latest version

#

yes, you can proceed. The board doesn't really do anything without an attached microcontroller board

#

you do NOT need to keep the "Seesaw only" USB plugged in normally. That is just for upgrading the crickit

#

This program will blink the onboard NeoPixel. You'll need to install the adafruit_crickit library and its prerequsites (adafruit_seesaw, etc.). Using circup is the easiest way to do that.

#

from adafruit_crickit import crickit
import time

print("Crickit version:", hex(crickit.seesaw.get_version()))

while True:
    crickit.onboard_pixel[0] = 0x003300
    time.sleep(1)
    crickit.onboard_pixel[0] = 0x000000
    time.sleep(1)

#

you can use most any Feather for this

#

e.g. one you already have with headers

#

the onboard neopixel (on the crickit board) does not need the barrel-jack power supply to work

First of all, ⁨circup⁩ is awesome and I had no idea it existed,thanks!

We are in business!

⁨Crickit version: 0x270f24a2⁩

#

Thanks for all of your help. I really appreciate it.
