The XIAO series of ESP32s is exactly that.

They are 4x the size though, almost exactly double in both length and width.

It's also got 15 times as many GPIO pins as the board in the fine article.

And this PCBA will be smaller than the battery in most applications anyway.

		It only has 14 pins, 3 of which are 5v, 3.3v, and ground, so slight exaggeration :-) point taken though

These are quite lovely. Ceramic SMD antennas are awesome.
