A log with a little delay, so that the project is more up to date !
This is Proto Zero, there were some small mistakes, but fortunately apart the MPU 9250 footprint, nothing serious. It allowed me to move forward on drivers.

Indeed, I advise you not to follow the recommendation of the datasheet, if you plan to solder it yourself ! I tried to extend pad on the new one.
There are also others improvements. I will come back over, but first I would like to finish update the project details.

Above Proto Zero, but I expect now Proto 0.1 Alias Bob...
