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.
