- Bus Pirate v4 vs v3 comparison
The Bus Pirate V4 is still a work in progress. If you want a reliable and fully tested tool, we still recommend the v3. It is actively developed and will be manufactured for the foreseeable future. Development on the V4 will continue, and we will let you know when we think it is the go-to hardware.
You can get a Bus Pirate v4 for $40, including worldwide shipping.
