i made my pcb with eagle...
but, I have some doubts:
1) wires width
16mil for signal ?
32mil for power supply?
2) GNDs
as I'll have 2 power supply different (from arduino for 164/165 & from external for LEDs), I know I have to connect GNDs.. but where should I do that on my circuit? near from the 2 supply input on the board? the position nevermind ?
3) result
I made an autorouting that results fine
what do you use for DRC ?
By using default, all is ok for me ... but should I use a special kind of rules for 4PCB services or BatchPCB services on the web?
help would be appreciated
