  1. Hi, I’m from South Africa and would like to purchase a Bus Pirate v4.
    You advertise: “You can get a Bus Pirate v4 for $40, including worldwide shipping”, but when I tried to buy it It would seem delivery is not free. Please advise.

    1. Interesting, he’s right! You might be better sending an email to Seeed Studio about that, as they are the ones that sell it. Other than that I’d suggest you try the DP ‘Contact’ link at the top of this page. The BP V3.6 is probably the better choice for you by the way, it’s much better supported I’m told, and more stable in general.

  2. Hi! Recently I purchased (from the latest batch) a Bus Pirate v.4 … It shows up as /dev/ttyACM0 in my Ubuntu system… But when I connect to it (with the help of “screen” or “minicom”) there is no communication!!! No response at all, no prompt, nothing. :-( What should I do to get a response from it??? BR//Pekka Akselin

  3. Hi again! If I run “screen /dev/ttyACM0” as root I get correct prompt and response!!! Ummm… I do not understand… :-/ … OK, more investigation. :-)

  4. Very wierd! No I suddenly get response as “normal” user tooo… I did “chmod a+rw /dev/ttyACM0” as alwasy before… The difference now is that the USB LED is not lit enymore, only the PWR LED… BR//Pekka

  5. Last comment for tonite: It depends on which physical USB port I insert it into…!!! Very strange. :-) BR//Pekka

  6. I want to order bus pirate v4 however its going to take a very long time to get it from Seeed is there anywhere else that is can be purchased and gotten any sooner without $43 shipping expense or on ebay from china

    1. That probably depends on where you are.

      Are you sure they want $43 to ship it to you? I’ve got PCB’s from Seeed a number of times that weighed a lot more than a BP and they came in a DHL bag (up to 1kg Satchel) for $24 and arrived at my door in Aus in 3 days.

    2. By the way, unless you have a specific need for the V4, DP still recommend getting the V3.x (I think V3.6 currently), as it’s much better supported than the V4.

      1. I just wanted v4 so that I don’t have to purchase another unit in the future but ill just be using it for pin testing my MacBook Pro efi. And I live in the US and just don’t want to wait forever and a day when I checked shipping time was up to 30 days. I’ve also read forums were everyone complains about shipping time.

      2. Yes I was of the same mindset, but when I asked Ian and others, they still recommended the V3.6 for the best supported and best reliability. They say the FW is far better developed / supported / reliable and will be for some time yet. Shipping time with normal mail would no doubt be relatively slow, but DHL are amazing at getting things across the globe very fast – I’ve never waited more than 4 days, even when that spreads across a weekend and usually it’s 3 days from when I get the Seeed email saying it’s been sent. One alternative in the US is Sparkfun, but they only have the V3. and from what I know it’s their own board design, not SOB form factor if that’s important to you, though I don’t think the V4 is SOB anyway.
