BusPirate-v3e-renderii.450

Nearly 1000 Bus Pirate v2gos were sold during Hack a Day’s preorder. It raised a ton of money, with all proceeds going to Mahalo, the company that owns Hack a Day.

Bus Pirate v3 is a complete redesign of the Bus Pirate v2go PCB, with improvements based on our experience running the preorder for Hack a Day. We optimized the PCB layout for production, and used a more widley available version of the PIC24FJ64GA002.

The top image shows the first revision of the v3 PCB. The stuffed, tested PCB is shown here. After working with the PCB we decided there were a few things we really didn’t like, so we made an ‘a’ revision.

The second version (below) has the LED resistors along the top edge of the PCB. This makes room for the 3.3volt power supply in the top corner, and eliminates some obscene routing.

The revised PCBs were submitted to our board house on Sept 9, and were mailed Sept 14. Normally they would arrive in 4-5days, but extra security surrounding a national holiday delayed the package in China until Sept 21. We would probably have the boards by now, but the tracking shows the package going to the wrong country. The address is definitely correct, it was just a random mail problem.

Today Seeed dispatched an additional shipment of BPv3 PCBs by DHL, which should arrive much faster. It’s a bit of a contest, which get here first: the DHL express packet, or the postal package forwarded from the Dutch Antilles?

BPv3 will be ready to go as soon as we test the final PCB, the article is already written and ready to publish. It’s a bit different that our usual design overview. We recount the development process that led to the current design, and dug up some very early ‘in house’ Bus Pirate prototypes. We’ll also talk about our experience running Hack a Day’s Bus Pirate preorder, and discuss how it influenced the v3 design.
