Sorry could not resist post this even if it looks crap.

The plan with this was to make an arduino nano compatible board using stm32 instead of crappy 8bit AVR.

But I decided to extend the board a bit.

* Added a switch regulator
* pinout for adafruit Tempsensor
* NRF24LO+ pinout.
* ESP8266 pinout
* Possibuility to mount a 2 FET onboard
* Possibility to mount standard I2C eeprom onboard
* OLED pinout adafruit compoatible
* No shitty FTDI chip needed since the STM has USB onboard and make it possible to flash STM using dfu-util no external adapter needed for flashing as in the case of AVR.

Okey the picture...

The board looks crap since I have not cleaned it and using alot of flux when soldering but that's what geek stuff is about
