Title: Bus Blaster Free PCB build
Post by: hmms on April 18, 2012, 07:42:53 pm
Finished Building the Bus blaster PCB.
Check it out. Soldering the FT2232 was the toughest part. I used Drag Soldering method to solder it . It was My first Attempt at soldering such a small pitch component .Here It is :)

Thanks for sharing your build! I should have a new bitstream for this hardware shortly, it is going into production.

hmms - would you please test out the new Bus Blaster v3 JTAGkey compatible logic buffer:

It works ok in my prototype.

hmmms, did you happen to save your partslist? I have a v3 board sitting here on the bench but I've just been too lazy to go through and pick all the parts out.

It's pretty much the same as V2.5:

But all passives are now 0603 (not 0805). There are a few extra parts too, I see if we can dig up a diff.

Sorry, I guess I should have been more clear. I meant like the digikey/mouser part numbers. Last time I peeked at it the cpld was only available from digikey, and the usb or something was only from mouser, I was trying to find maybe everything from digikey but then I got involved in some other project. I'll have to dig it out again I just don't have time until finals are over.

The CPLD is only digikey. The other stuff should be available anywhere. I'm sorry, we only have mostly mouser links on our partlists:
