guys there are now two bitmaps of the single sided board on the website. I added a second that is probably easier for the DIY guy to drill.

I just had a couple of questions. The part list shows 370QBK-ND Digi-key says that this isn't a valid part number. I can't find a 370 ohm resistor from Digi-key. What do I need to order.

I also was wondering how to print the copper picture to the actual size I need for the board.

Thanks,

My bad, 390 ohm Digikey P/N 390QBK-ND. Just make sure what you print it with is set to a reolution of 600 DPI. Microsoft Photoeditor as example.

[tekno]

I used metel film on all the resistors but the power resistors (.2 ohm)

Also for the signal resistors 1/4w should be good.

I upadated the webpage again. Fixed the P/N on the resistor. I selected a 390 ohm, that resistors function is simply to control the brightness of the power LED. 270 ohm is about the minimum, 510 about the max. Also added instructions on how to get a correct copper size printout.

techno, bruiser, HansS, andyew
Any of the Single Sided 3397 boards built yet?

Nope, sorry, a bit busy with working for the boss: too many work, less sleep, less free time.... But maybe in the weekend....

I uploaded a Rev A to the board on the website. All rev A does is changes the layout slightly to give more copper area to the ground plane and give a little more clearance in a few tight spots to help toner transfer people. The original infor is there as well.
