If you’ve been involved with electronics and hardware hacking for awhile, there’s an excellent chance you’ve heard of the Bus Pirate. First introduced on the pages of Hackaday back in 2008 by creator Ian Lesnet, the open hardware multi-tool was designed not only as away to easily tap into a wide array of communication protocols, but to provide various functions that would be useful during hardware development or reverse engineering. The Bus Pirate could talk to your I2C and SPI devices, while also being able to measure frequencies, check voltages, program chips, and even function as a logic analyzer or oscilloscope.
Bus Pirate 3, circa 2012
The Bus Pirate provided an incredible number of tools at a hobbyist-friendly price, and it wasn’t long before the device became so popular that it achieved a milestone which only a few hardware hacking gadgets can boast: its sales started to get undercut by cheap overseas clones. Of course, as an open hardware device, this wasn’t really a problem. If other companies wanted to crank out cheap Bus Pirates, that’s fine. It freed Ian up to research a next-generation version of the device.
But it turns out that was easier said than done. It’s around this point that the Bus Pirate enters what might be considered its Duke Nukem Forever phase. It took 15 years to release the sequel to 1996’s Duke Nukem 3D because the state-of-the-art in video games kept changing, and the developers didn’t want to be behind the curve. Similarly, Ian and his team spent years developing and redeveloping versions of the Bus Pirate that utilized different hardware platforms, such as the STM32 and ICE40 FPGA. But each time, there would be problems ..
