My new PYB Nano board is coming, I am testing it now.

main feature:
  • STM32F401CEU6 microcontroller
  • 2 uart
  • 3 I2C
  • 3 SPI
  • 10 ADC input
  • RTC
  • battery input
  • one user button and one RESET button
  • 4 user LED, with intensity function support
  • with MMA7660 sensor
  • usb power or external power (12V input maximum)
  • low cost
  • very small

There is definitely a need for a low cost GP micropython board.
I would suggest to make MMA7760 an option to reduce cost further.

You can now get very powerful nano Linux SBC's with multitasking , WiFi and full python or whatever you want to program with.

For less than $13:https://www.seeed.cc/LinkIt-smart-7688- ... 650.html#!

And with integrated Arduino AtMega3 processor for real time I/O and control:https://www.seeedstudio.com/LinkIt-Smar ... -2573.html

These Linux SBC are in a different category, but considering the power and features are ridiculously cheap.

Do you have a price and when are you going to sell it?

LinkIt smart 7688 is great, I have a LinkIt smart 7688, but I love micropython more.

My purpose is not selling boards, I make PYB Nano board in order to let more people to know and try micropython. There are many people are interested MicroPython in Chinese, but have no appropriate baord. PYBoard is very nice, but it is not easy to buy, so we make the PYB Nano board. It is smaller and cheaper, PYB Nano board cost about $8.4.

That board sounds interesting for the price, especially the Duo version which has two data-capable USB ports...

Do you think it could be made to work as a USB Host and Device at the same time ? Like a keyboard remapper or such ?

STM32F469BIT6 with DSP core, so it is expensive than STM32F401. And it seem that micropython has not support STM32F469, I have try port it to STM32F469DISC last week, but not success.

Yes, I think it will work. Because USB host is from MT7688A, and usb mcu is from ATmega3aU4.

Thanks for that answer ! Any idea if Python could handle both sides, or C should be used on the Arduino end ?...

USB mcu side is arduino, it doesn't support python, only C code may use.
