We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service.
This is the first version of the Bus Blaster JTAG programmer. It’s been power-up tested and the FT2232 enumerates on the PC. One of the buffer footprints has mask over pads, so you’ll have to scrape it away before soldering. We have two extra PCBs to give away this week, just ask for one in the comments.
Testing update: The Bus Blaster is working and on it’s way to manufacturing. Join us to discuss Bus Blaster v2, which will have a CPLD buffer to increase flexibility and reduce the cost of the design.
