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</i>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.
