GoKawiilOpen-source ESP32 Bit Pirate firmware turns ESP32-S3 boards into multi-protocol hardware debugger
ESP32 Bit Pirate is a free, open-source firmware project that converts common ESP32-S3 development boards into a versatile bench tool for probing dozens of hardware protocols including I2C, SPI, UART, JTAG, SWD, CAN, LoRa, Wi-Fi and BLE. Users can control it via USB serial, a browser-based Web CLI over Wi-Fi, or Web Serial, and the accompanying web tools support flashing, logic capture and chip programming without installing desktop software.
GoKawiil's interpretation of the reporting above, not reported fact.
By consolidating dozens of protocol analyzers and programmers into one low-cost, browser-accessible firmware, the project lowers the barrier for hobbyists, students and engineers to debug embedded hardware without buying separate specialized tools. Its compatibility with many existing ESP32-S3 boards and support for scripting also makes it attractive for building repeatable, automated hardware test labs.
- Runs on any ESP32-S3 board with 8MB+ flash, no PSRAM required
- Supports dozens of protocols like I2C, SPI, JTAG, CAN, LoRa and BLE from one firmware
- Offers browser-based tools for flashing and logic capture, reducing need for desktop software
