Built around the Raspberry Pi Pico 2 with the RP2350 microcontroller, it provides higher clock speeds and improved timing accuracy compared to previous versions, enabling more precise glitch attacks against microcontrollers and secure elements. The board generates crowbar-style voltage glitches using two high-power MOSFETs capable of switching up to 66 amps, making it a powerful yet affordable alternative to professional tools like the ChipWhisperer Pro. Version 3 introduces a selectable power supply with four voltage levels (1.2V, 1.8V, 3.3V, and 5V), allowing it to interface with a wide range of target microcontrollers. The improved Schmitt trigger inputs on the EXT1 and EXT2 channels feature adjustable threshold, attenuation, and hysteresis via onboard potentiometers, providing reliable triggering across different signal conditions. Level shifters based on the SN74LVC8T245 handle voltage translation between the RP2350 and the target device, while the multiplexing output stage enables rapid switching between voltage levels during glitch operations. The PicoGlitcher is paired with the findus Python library, which provides a complete fault injection framework including parameter search, UART-based triggering, and automated glitch campaigns. The accompanying documentation at fault-injection-library.readthedocs.io includes detailed tutorials covering attacks against common microcontrollers such as STM8, STM32, and various ARM targets. Hardware design files including KiCad schematics and Fritzing diagrams are available in the GitHub repository under the GPL-3.0 license, making the entire platform fully open source from firmware to PCB layout. ## Where to Buy - [Tindie](https://openhardware.directory/r?to=https%3A%2F%2Fwww.tindie.com%2Fproducts%2Ffaulty-hardware%2Fpicoglitcher-v3%2F&ref=openhardware.directory&product=picoglitcher-v3&source=md-export) — $54.00 - [Faulty Hardware](https://openhardware.directory/r?to=https%3A%2F%2Ffaultyhardware.de&ref=openhardware.directory&product=picoglitcher-v3&source=md-export) — €55.00 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Ffaultyhardware.de&ref=openhardware.directory&product=picoglitcher-v3&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2FMKesenheimer%2Ffault-injection-library&ref=openhardware.directory&product=picoglitcher-v3&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Ffault-injection-library.readthedocs.io%2F&ref=openhardware.directory&product=picoglitcher-v3&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2FMKesenheimer%2Ffault-injection-library%2Ftree%2Fmaster%2Fschematics&ref=openhardware.directory&product=picoglitcher-v3&source=md-export) ## Tags `voltage-glitching`, `fault-injection`, `hardware-security`, `rp2350`, `raspberry-pi-pico-2`, `open-source-hardware`, `crowbar-glitch`, `penetration-testing`, `side-channel`, `findus` ## Images ![PicoGlitcher V3](https://nbg1.your-objectstorage.com/openhardware-directory/entities/picoglitcher-v3/87166379ea57.JPG) --- [View full device page](https://openhardware.directory/devices/picoglitcher-v3)
