Default New boards on the way, BPA300

So i have created my own BPA300 boards. They should arrive in a week or so. Since I make a living on placing SMD components on PCB's i used mostly SMD-parts.

I dont now how many pcbs i will get, but around 10 pieces i guess. I get them for free from one of our suplier so it depends of how generous he feels

I will only need 2 so if they work and if someone want boards for free, let me now. They mesure 8.85 x 1.95 inches, or 22.5 x 4.92 cm.

But as I said, i dont now how many I'll get so I cant promise anyone anything really

SMD-parts, I can pre-mount them if requested. Best regards, Calle.

That is a very generous offer!

How about a schematic and parts list? I would be most appreciative. Some one else could take you up on your offer of the free boards...

Thanks!

Offcorse. You are nr 1 on list. But as I said, I cant guarantee any boards yet, as I dont know how many i will get.

I will post schematic and partlist tomorrow, Im at my girlfriends place now and I dont have it right now. I could post the gerber-files to if someone want them.

If there is a big interest then I could order bords and "sell" them to manufacture-cost.

Best regards..

Very nice design CJ900RR but... can you make supply tracks a little wider? You will need a lot of power for six LMs

Thank you veteran. The supply tracks (that you dont see cause they are at the bottom-side is 0.86 inches wide. Do you think that that is'nt enough?

Best regards...

You might want to thicken up those output traces while you're at it.
