The Bus Pirate v3b with an extended temperature range PIC is now in stock at Seeed. The extended temperature PIC doesn’t mean anything, it’s just a quirk of our tiny production runs.
Get a Bus Pirate for $30, including worldwide shipping at Seeed Studio. Adafruit also has the Bus Pirate and probe cables in stock and ready to ship.
I thought you skipped the tantalium (difficult word :D) caps in v3b?
