Bus Pirate v4 is back in stock at Seeed Studio. The Bus Pirate is an open source hacker multi-tool that talks to electronic stuff. It’s got a bunch of features an intrepid hacker might need to prototype their next project.
You can get a Bus Pirate v4 for $40, including worldwide shipping.

We received this BPV4 days ago, but we don’t have USB 2 TTL bus driver, it is said FT232 driver. As a result, we can’t find the COM port. Could you please send me this driver?
Thanks,
Shiyang Gao
Hi the Bus Pirate v4 only needs the .inf file to let Windows know it’s a CDC device. you can find the inf file in our SVN http://dangerous-prototypes-open-hardware.googlecode.com/svn/trunk/Bus_Pirate/package/BPv4-inf-driver/
Hi Filip,
Thank you very much. Now I successfully installed the driver and BPv4 is recognized.
And then I followed the instruction http://dangerousprototypes.com/docs/Bus_Pirate/zh-hans to type “?” But I didn’t see the help information displayed in website. That means I am not connecting? Is it because I need to download firmware prior to any operation?
Do you have a phone number? Can I talk to you for queries?
Best wishes,
Shiyang Gao
Hi Shiyang,
you need to setup the terminal to 115200 baud, 8bit, no parity, 1 stop bit, no flow control.
now open the com port that the bus pirate connected to. when you hit enter do you see “HiZ>”
I’ send you my email, from which we could talk over gtalk.. I’m available from 8:00-17:00 Central European Time (CET)
