There pictures are certainly deceiving
. I had to solder some 0603 SMD capacitors on to the PCB yesterday, and they were really small. The 0402s are not clearly visible at all. It is amazing how you are able to solder them neatly, without shorting the adjucent LEDs!
Also, where do you get those 0402 white LEDs from? I looked at
www.digikey.com and
www.mouser.com and they don't have them. They have the red, orange, yellow etc, but not the whites. The whites start only at 0603 package.
And what is the part number of the H-bridge you are using? Both mouser and digikey have the H-bridges made by Zetex, but it looks like they come in a slightly larger package than what you are using (I think they are called SM8, 8 pin version of SOT223).
Thanks!
