See the latest version in the documentation wiki. Raw SPI is a new mode that provides high-speed access to the Bus Pirate SPI hardware. It was developed in conjunction with Michal Ludvig, so that AVRDude can use the Bus Pirate to program AVR microcontrollers and EEPROMs. Firmware v2.3 includes two new raw I/O modes that […]

AVRDude patch: Program AVRs with the Bus Pirate
UPDATE: Bus Pirate support is now included in the current AVRDude SVN version. Michal Ludvig submitted a patch that gives AVRDude support for programming ATMEL AVRs and serial EEPROMs using the Bus Pirate. AVRDude parses ASCII terminal output at the moment, but we’re working on a raw SPI mode for better speed and performance. More […]
Bus Pirate: Major UART fix
There was a major bug in the speed setting code for all libraries. At some point the speed variable was reduced to a single bit, so only the first two speed settings in any library worked correctly. This had an especially noticeable impact on the UART library. Since this is a major issue, we’ve made […]
Last Bus Pirates in preorder 1
The Bus Pirate hardware v3 preorder has been a huge success. Thank you for your support! The BPv3 rollout has been pretty low-key. We haven’t posted the Instructables version, and the new design hasn’t been linked by any blogs. Only readers and forum members know about the new hardware, but we’ve almost run out of […]
Chips: 24AA02E48 I2C EEPROM with MAC address
See the latest version in the documentation wiki. The 24AA02E48 is an I2C EEPROM with 256bytes of data storage. It’s similar to other EEPROMs we’ve looked at in the past, but this chip has a 48bit EUI-48 ethernet MAC address permanently burned into the upper-most six bytes. This is an easy and cheap way to […]
Free PCBs: Bus Pirate v3
To celebrate the completion of Bus Pirate v3, we’re giving away two BPv3a PCBs. V3a is the second and final revision of the Bus Pirate v3 family, the same PCB that will go into production. If you’re up for the challenge of building your own BPv3, just ask for one of these PCBs. Get assembled […]
Prototype: Bus Pirate BPv3
UPDATE: v3b is the latest Bus Pirate revision, read about the changes here. BPv3 is the latest hacking multi-tool from the Bus Pirate project. It connects to a USB port and interacts with electronics through a simple terminal interface. Use it to see how much of your private information is stored on smartcard SIM chips. Explore […]
Free PCBs: The last Bus Pirate v2a PCBs
BPv3 is ready, so we’re getting rid of any extra Bus Pirate v2 PCBs. If you want a Bus Pirate v2a PCB, just ask for it in the comments. We have at least two, possibly three or more. PCBs by Seeed Studio and one by BatchPCB. The Bus Pirate v2a was really handy for developing […]
Bus Pirate: Easter egg submissions
There’s an Easter egg in the Bus Pirate firmware. Type ‘+’ in the Bus Pirate terminal to see the current configuration bits for your PIC and some ASCII art. Now that we’ve announced it, we’ll change the key and message in the next firmware update. Send us your ASCII art, it might be included in […]
Bus Pirate: BPv3 is here
***Read about BPv3 here*** BPv3 circuit boards arrived today. By popular vote, the final PCBs will be RED. Tests look great, we’ll be ready ASAP. It’s National Day in China, so it might be a few days before Seeed is available to start the preorder. Sorry about the lame posting the last few days, we’re […]
Bus Pirate: BPv3 final update
Nearly 1000 Bus Pirate v2gos were sold during Hack a Day’s preorder. It raised a ton of money, with all proceeds going to Mahalo, the company that owns Hack a Day. Bus Pirate v3 is a complete redesign of the Bus Pirate v2go PCB, with improvements based on our experience running the preorder for Hack […]
Upcoming Bus Pirate demos
Here’s a few upcoming Bus Pirate chip demonstrations: MCP23016 8bit IO expander DS2450 1wire analog to digital converter SD cards 38kHz infrared receiver EEPROM programmer/dumper We’re always open to requests, and we’ll send you a free PCB if we use your chip suggestion for a demo.
Open source logic analyzer clients
Today we played with a few open source logic analyzer clients in preparation for an upcoming prototype. The best we found is SUMP, written in Java. There’s also compatible host software for several FPGA development boards, we found even more ports floating around the web. SUMP has a SourceForge page, but it doesn’t look very […]
Free PCB Sunday: #twatch v1
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few professionally-made PCBs from one of our past or future projects, or a related prototype. This week we’re giving away two PCBs for the 24FJ64GA002-based v1 #twatch development board, PCBs […]
Tracking orders from Seeed Studio
We’ve gotten a few questions about tracking packages from Seeed Studio, like the Bus Pirate and #twatch preorders. Seeed uses Hongkong Post by default, in our experience these packages usually take 4-7 days to arrive. When your order ships, Seeed sends a status update with a tracking number like EE123456789HK. Use the Hongkong Post tracking […]
Realterm for the Bus Pirate
BiOzZ posted an Instructable that shows how to setup the open source Realterm serial terminal to work with the Bus Pirate.
#twatch network LCD preorder update
The #twatch ethernet LCD backpack preorder is over, shipments will start around October 10, 2009. Our first project was a big success. Thank you for participating with comments and preorders! If you missed out on the preorder, Seeed is making a few extra units you can buy for $45, worldwide shipping included. We don’t plan […]
Bus Pirate: New chip demonstrations
Have you used the Bus Pirate to interface an interesting chip? Send us a copy of the session output, if we use it on the site we’ll send you a free PCB. Is there a part you’d like to see demonstrated with the Bus Pirate? Please make a request in the comments, if we use […]
Bus Pirate: Python library
audiohacked has started a python library for the Bus Pirate. So far, it’s been tested as an EEPROM dumper: I have started writing a python library for the bus pirate. It’s ugly and messy, but I was able to use it to dump the firmware from an SPI chip… You can contact me if you […]
Network LCD (#twatch) availablility update
**UPDATE*** Seeed is listing the #twatch again. They located additional PIC chips. The #twatch preorder has an estimated October 10 ship date. #twatch production is limited by the number of PIC 18F67J60 ethernet microcontrollers Seeed can find for immediate delivery. Here’s some of the options at this point: Seeed locates more PIC18F67J60s, they add more […]
