Do any of you experienced PCB layout makers have any suggestions for building this part?
I broke the orientation rule for placing one of the TLC5940 since I think it will make running traces a lot easier.
The Atmega 168 is a QFN package (the other SMD ones are unavailable at both digikey and mouser). Does the ground plane under the QFP have to be soldered? If not, is it OK to run vias under the QFP?
The LEDs and the control circuitry are supposed to be on separate sides of the board.
