New boards have arrived

The new boards

To produce the latest revisions of the modular robotics boards I again used OSH Park. Although their quality is of a very high standard, they are particularly slow and relatively expensive, so I may re-consider using a different PCB production service.


The most complex board previously was the Edgebot and this ironically required little work;

However, with the motor controller I removed the voltage regulator as it is currently not required and using space, this allowed for a secondary trim-pot. The outline also had re-work as there would be no price difference (OSH Park charge for the bounding box area, not the actual area) while providing a larger area, therefore components were less constrained to layout;

As the previous Photovore PCB did not seem to work at all and required a quick perfboard prototype, the PCB had to be completely re-designed;

I hope to assemble them in the next few days, I will post results on how that goes.
