ESP32 Bit Pirate is open-source C++ firmware that turns an ESP32-S3 board into a multi-protocol hardware debugging and analysis workbench, inspired by the Bus Pirate. It supports sniffing, sending, and scripting across wired buses (I2C, SPI, UART, JTAG, 1-Wire) and radio protocols (Wi-Fi, Bluetooth, Sub-GHz, RFID, Infrared) via a serial terminal or web-based CLI.

Use cases

• sniff and interact with i2c and spi buses on embedded devices
• dump eeprom and spi flash chips
• debug uart serial communication on hardware
• scan and explore jtag/swd debug ports
• capture sub-ghz and infrared radio signals
• turn a cheap esp32 into a bus pirate alternative
• test bluetooth ble devices with scanning and spoofing
• perform wifi packet sniffing and network analysis

When to choose

• you need a low-cost multi-protocol hardware debugging tool
• you want a bus pirate alternative with web-based CLI and wireless protocol support
• you're learning electronics and embedded protocols hands-on
• you need to sniff, dump, or script interactions with i2c, spi, uart, or jtag targets

When to avoid

• you need a polished commercial logic analyzer with high sample rates
• you only work with high-level software and never touch hardware
• you require certified/safety-critical testing equipment
• your board is not an ESP32-S3 compatible device
