Hi @Acoustics123 👋 Thanks for submitting this pull request, and welcome to GitHub!

There are a couple of extra fields required (like published false for in-development components) in the component JSON, and we've recently setup product images to be pulled from the Adafruit store if not uploaded (which is now our preference for Adafruit components).

These requirements are usually checked by CI(continuous integration) in GitGub Actions, also seen in the Checks tab/box, but these are disabled for first time contributers (until a maintainer allows the first CI run which I've now done for you)

Take a look at something like the vl53l0x i2c component as an example, or here's one I'm adding soon in another PR: https://github.com/adafruit/Wippersnapper_Components/pull/183/files

Are you also planning to add the corresponding driver to the main firmware repository https://github.com/adafruit/Adafruit_Wippersnapper_Arduino ? If not then we'll probably leave this unmerged untill the driver gets started/done too by us (I've got one and it's on my long list so am happy to help) or someone (yourself or another contributor).
