Title: PCB layout
Post by: Doktor on April 04, 2010, 03:40:24 AM

Hello everyone!
I'm new to robots, and to the forum, too.  ;D
I'm working on a project that quite similar to the 50$ bot, but not exactly the same. I'm using DC motors with a motor driver circuit. I'm building that schematic: http://www.hobbielektronika.hu/kapcsolasok/files/354/kapcsrajz.jpg (http://www.hobbielektronika.hu/kapcsolasok/files/354/kapcsrajz.jpg).
I've designed a PCB layoutfor it, but because this is my first robot and first PCB desing, i'm not sure if it's correct.
I'd like someone to check it according to the schematic.

Here's the PCB layout (i can't even use EAGLE, so i used paper and pencil :D ):

Bye and thanks for all the replies.

EDIT: the red line is a piece of wire, i can't made it without a crosswire.

Hi,

Perhaps you can use this (http://That.Homepage.dk/PDF/ATmega8_Board.pdf).
