Ballbot PCB (part 2)

So with a few modifications to the PCB design, here’s what I’m sending out for production.


Note. Most of what appears to be the silkscreen is actually on the documentation layer. It now features a 12 pin port with 5v, 3.3v, SPI, I2C, Serial, and two digital pins broken out, to link to an expansion board for wireless communication etc.

The board fits in a 3.56” by 3.19” rectangle.
