That looks like a much more reasonable form factor than the original PyBoard.

But with fewer I/O pins...

And lower cost.

It's nice to see you've made your own board.
It would be far more interesting if you give some more information, like schematics, bottom layout, does it have sdcard connector, ...

PYB Nano V2 is upgrade from PYB Nano V1.1, I put all designer file in here:
https://github.com/micropython-Chinese- ... PYBNanoV11
PYB Nano V2 designer file will be update a little late.

Thanks, that is more interesting.

You design looks nice and I hope your enjoying designing and building your own boatrd.
I am watching this thread as am really interested in a small form factor STMF4. You design looks nice.
The Ardunio guys are doing the same thing. They very much like small form factor boards and the blue pill (STM32F103) is super popular but people have been looking for more capable board in same form factor and many of them have been looking at the original PYBoard as it is a fairly small STMF405rg.
The Ardunio guys are close to getting a manufacture to build there design of a board same size as blue pill but with a STM32F405rg and a SD card with battery circuits and separate UART pins and separate SW pins

There is some images around of the built prototype but couldn't find them right now

PYB Nano (STM32F411) has no SDIO, so I have no design a SD connector, but you can using SPI to connect a SD.

BluePill is small and nice too, but PYB Nano is smaller and faster. And we like python more.
