So here we go, the first reveision of the PCB of the wiseboard. Now you will notice that is there is still a handful of airwires to the ground plane. I didn't feel that it was worth the trouble considering that I found the TPS65186 from the WiFi Epaper project here on This chip is an all in one power supply chip that is cheaper and more capable than buying all of the separate chips that would otherwise generate the voltages required.

This chip has all sorts of bells and whistles and is entirely configurable over I2C. Hopefully I will be able route the whole thing with a 6mil trace width. More to come!
