Marius can you upload the schematic and layout in pdf so people not having Eagle (?) can also provide feedback? Or just send it by mail.

Hello all :)

I think i have finished my breakout board.
Can some people check my design ? (It would be nice if at least two could check my design)
https://github.com/NeoFromMatrix/stm32f4discovery_daughterboard

My ideas for this design:

* Minimum site (currently 100x70mm)
* servo can be supplied with seperate power
* pinout for each connection

Problems that maybe occur:
* interference between pwm and adc
* interference between pwm and pusbutton
* spi select slave maybe not on the apropriate spi channel
* right caps used ??? (low esr), how much µF shoud i use ???

Currently it doesn't fit completely under the discovery board, hold your discovery board on the screen to see what i mean.

I can order a batch at seeedstudio(costs 3€+shipping for one pcb), but this will be organized later !!!, currently I'm only searching for improvement capabilities.

Maybe i can also order some components at mouser and sell a complete diy solder or already soldered kit for prime cost + donation ;)

Best regards
Marius

I have sent the eagle files to Marius (Pheffer) as he can make it better equipped for the paparazzi
if i understood him well.
I designed the board with me as a user only in mind so the layout might not be optimal.
