@audioguru, thanks for the friendly welcome. You must have looked only at the schematic and this is not mine.... it's from Kade. He made the advanced version with a total different pinout and new code. In the PCB's above, I have taken your advise. sorry for confusion ;D I would like to know if my routing and the general layout is ok, because I mixed three into one. Normally I took a ready made layout etch it, order the necessary parts, solder it and hope that everything goes well ::) I really have no clue of all the different parts/values and stuff :-[ Thanks nase
