Next OpenMV camera is going to use STM32F7.
Also there is a more interesting STM32H7 CPU comming in 2017 (part of models already exist)

I think it is a good idea to co-operate with others by using similar CPU (at least F7) so both projects could bring support for this CPU together.

One idea I would like to see would be to break out the gpio pins using the same high density connector as the tinyduino https://tinycircuits.com/collections/al ... um-version to keep the board small.

Then sell separate adapters to accept raspberry pi hats and arduino shields and provide a breadboard compatible male dip pins.

Damien, is there any news about your plans?

It bugs me more than it should that 2 of the pyboard LEDs are rotated 90 degrees.

The pyboard was designed to be user friendly and reliable on a 2 layer PCB. That includes:
  • * User friendly pinout with symmetrical X and Y skin positions that don't match the MCU and make routing difficult.
    * Quiet Analog pins with their own GND and Vref.
    * Guard rings around the crystals and SD card clock to minimise crosstalk.
    * Solid power, ground and bypassing of all the MCU pins.
That's hard on a dense 2 layer board. I would much rather have a reliable board than a pretty one. The LEDs are where they are because they are low priority in terms of design goals and tidying them up would have compromised reliability, eg removing the guard GND around SD clock.
