PYB Nano V2 mini board

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

BluePLll:

• MCU: STM32F103

• Speed: 48MHz

• Size: 74 x 25 mm

PYB Nano:

• MCU: STM32F411

• Speed: 96MHz

• Size: 48 x 18 mm

That's a nice form factor. I'd love to see them available worldwide.

My 5c to this port:
Recently spotted local Espruino board with the same STM32F411CEU6. And decided to give it a try. Also, it is x2 times more exensive, than PYB Nano V2.

That's not a 100% match by pinout, but I can live with it.

So far - REPL over USB is functional.
