The first complete release package for Bus Pirate v4 is now available in the forum. This includes a working bootloader and firmware based on the new open source USB stack, utilities, and complete source code. If you have the v4 hardware, any testing is greatly appreciated.
There are still a ton of bugs to fix, and many features simply don’t work. Even after the v4 launch, v3.5 will remain the premier Bus Pirate hardware. There’s no ETA on v4 hardware or firmware, but we think it would be a coup to announce a v4 test batch at the Open Hardware Summit in a few weeks.
If you’d like to get in on the development action, there are a couple Bus Pirate v4 prototypes available at Seeed Studio. They do not come with a bootloader, you’ll need to program it yourself. The prototype is quite expensive to discourage lookie loos, but active code contributors get a full or partial refund from us.
Over a year ago we released the first Bus Pirate v4 hardware. It uses a PIC with integrated USB, it needs a USB stack. Microchip has a free-as-in-beer USB firmware for the PIC microcontroller, but it can’t be redistributed. We think the Bus Pirate exemplifies everything good and wholesome about open hardware. There’s no way we’d release it using non-distributable source.
It’s firmware development week month here at Dangerous Prototypes. Up next later today: IR Toy firmware v20-final.
