This looks awesome, I'd love to get one. Question, what's the advantage over something like the ESP32C3 and the like? Just even smaller?

I'm interested in this too. I've been using STM32 NUCLEO boards, which are cheap and capable, but even the smallest ones are noticeably larger than this. I'd love to see an STM32 version of this project.

Very nice. I am wondering -- why have a devboard this small?

That thing is sexxxy. Very nice board, beautiful documentation.

Title is inaccurate, it's really designed to be about the size of a USB-C receptacle , the plug is the other side (in this case the part of the cable that plugs in to this board)

That's not a plug. To be precise, that's the opposite of a plug xD

I dream of an open board like the yubikey nano. This is very nice!

I recently got my hands on an M5Stack NanoC6 ( https://docs.m5stack.com/en/core/M5NanoC6 ), it's also quite small and I'm pretty happy with it. It has onboard IR and a Grove connector, good enough for IoT projects at home.
