Bus Pirate v4 is back in stock at Seeed Studio. Compare it to v3:
- Four times more memory space

- Data storage EEPROM to hold settings
- Pull-up voltage selections: 3.3volt, 5volt, or external supply
- 2 extra I/O pins
- Multipurpose button
Bus Pirate v4 is new and shiny, but it will lag behind the trusty v3 for a while. If you want proven goodness we still recommend the v3, it’s actively developed and will be manufactured for the foreseeable future. v4 will continue to improve, and we’ll let you know when we think it’s the go-to hardware.
You can get a Bus Pirate v4 for $40, including worldwide shipping.
