After a very intense week of work, we managed to finish the PCB.
Since we have to clip on another board, there were a lot of constrains:
It wasn’t easy to draw with precision the borders and the wholes in the board.
The space available was limited by the size of the ball.
We had to reassign the pins to optimize routing.
The were very carefully on the placement, again to optimize routing.
But now, the board was checked, and it’s about to be send to production!
Everything is going well, let’s start software.
