This particular jacket runs a pre-set pattern on a Trinket M0 that I programmed using a CircuitPython LED code generator. However I have made a version where the Trinket is connected via USB to a RasPi Zero W running as a wireless hotspot and since the Trinket shows up as a drive on the RasPi Zero W, you can program it wirelessly. ABove is her video of programming the LED jacket via an Apache server running on the RasPi Zero W.
