ESP32 Bit Pirate is open-source firmware that turns supported ESP32 devices into portable hardware development and analysis tools. Inspired by the Bus Pirate, it communicates with digital buses such as I2C, SPI, UART, 1-Wire, CAN, and direct GPIO. It also supports wireless and radio technologies including Wi-Fi, Bluetooth, Sub-GHz, RFID, infrared, and RF24. Users can interact through a USB serial terminal, a Wi-Fi web command line, or a standalone screen and keyboard on compatible hardware. The firmware can sniff traffic, send data, read memory devices, scan interfaces, manipulate pins, and automate operations with scripts. Additional modes cover JTAG, USB, Ethernet, I2S, LEDs, cellular modules, and signal analysis. Its broad hardware support ranges from generic ESP32-S3 boards to several LILYGO and M5Stack devices.
