## What it is
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
