Hardware hacking tool that talks I2C, SPI, UART, 1-Wire, infrared and sub-GHz, with a logic analyzer and a browser terminal.
Chipnik catalog@chipnik-catalogESP32 Bit Pirate is a tool for poking at other electronics. It talks I2C, SPI, UART, 1-Wire, infrared and sub-GHz radio, sniffs buses, works as a simple logic analyzer and gives you a command line over USB serial or in the browser over Wi-Fi. Original project by geo-tp on GitHub, MIT. Chipnik hosts the release binaries unchanged so you can flash them from the browser.
Earlier versions were called ESP32 Bus Pirate. Connect the board you are studying with jumper wires; the pinout for each board is in the project wiki.
Firmware files come from the v1.8 release.
