This firmware turns an inexpensive ESP32-S3 board into a multi-protocol debugging and hacking tool, inspired by the original Bus Pirate and the Flipper Zero.
It currently supports a wide range of protocols and devices, including I²C, SPI, UART, 1-Wire, CAN, infrared, smartcards, and more. It also communicates with radio protocols as Subghz, RFID, RF24, WiFi, Bluetooth.
Compared to existing solutions, the focus is on:
- Accessibility — runs on cheap ESP32-S3 hardware (around $7–$10).
- Versatility — one device can probe, sniff, and interact with multiple buses.
- Extensibility — open-source and modular, making it easy to add new protocol support.
I believe this could be useful for hardware hackers, security researchers, and hobbyists looking for a low-cost, flexible alternative to commercial tools.
