(feature request) - new product - PicoS3; an inside-your-usb-a-port-sized full-featured MCU !

[gitcnd]

I'm dreaming of the PicoS3 (new invention).

It's half the size of your NanoS3, with USB-A pads on the bottom, and low-profile enough to plug directly in to a USB socket, leaving nothing more than the width of the antenna poking out, beside which is a 4-pin JST SH socket (which can be used for I²C when plugged in to a host USB device, or which can be used to power the device if it's not connected inside a USB-A socket.

It's so tiny, customers could even "hack it inside" to the plug of an existing cable, without even knowing it's inside there.

It would "expose" as many as possible other useful pins as teeny-tiny solderable points on the underside, which are covered-over with a solder mask (if we want to use them, we need to scrape off the mask first), and the very edge of the connector (below the antenna) exposes enough non-masked contact area pads that sensing a finger-touch on those exposed pins can be managed).

If there's room to cram the WS2812B behind the antenna so we can at least see its glow from inside there, that would be the icing on the minicake !
