Good to hear you are still on it!

To save you some time: CE you can award yourself and provide documents only when asked later - and since you don't have high voltage circuitry or sharp corners you can basically slam the CE logo on your product. If you let your boardhouse use leadfree solder RoHS is also no biggie. FCC you don't need unless you are sneakily making it a Bluetooth keyboard haha!

But since you are doing certification; do you have a working proto yet? The update lacked any pics or vids.. Good luck ramping up for mass production!
