ESP32 Bit Pirate is open-source firmware that turns your device into a multi-protocol development and analysis tool, inspired by the legendary Bus Pirate. It supports sniffing, sending, scripting, and interacting with various digital protocols (I2C, UART, 1-Wire, SPI, etc.) via a serial terminal or web-based CLI. It also communicates with radio protocols like Bluetooth, Wi-Fi, Sub-GHz and RFID. Turn a $5 ESP32-S3 into a browser-based hardware workbench.The Bit Pirate firmware is complemented by scripting, hardware dock, extension, adapters, browser tools, documentation and practical embedded workflows to enable comprehensive hardware debugging and development with serial interfaces or Wi-Fi connectivity. https://github.com/geo-tp/ESP32-Bit-Pirate

Free browser-based tools for serial communication, ESP and STM32 flashing, SPI flash programming, AVR programming, I2C/SPI controls, and logic analysis. Connect compatible hardware directly from your browser to inspect, program, and debug embedded devices without installing a desktop toolchain.

The value for money is crazy on these boards, in my opinion. I'm planning on using these as a cheap replacement to a KVM. Flashing esp bus pirate (https://github.com/geo-tp/ESP32-Bus-Pirate) and leaving it connected to whatever device I want to control ( remotely in my case), is quite handy. The power draw is negligible so I just leave it always on connected to my wifi.

I've been toying with the ESP32 architecture for a few years. (I began with ESP32-DevKitC in 2022.) I recently got four ESP32-S3 modules with the intent of trying out the ESP32 Bus Pirate (https://github.com/geo-tp/ESP32-Bus-Pirate). I hadn't heard about any Linux ports until I saw your comment here. Thanks! The "playground" Linux port looks interesting, but it hasn't seen any updates for nearly a year. Still, I'm going to try it on a ESP32-S3 N16R8 and see how it goes. It's funny, because I first ran Linux (SLS & Yggdrasil) on a PC with a 33MHz clock, 32MB RAM, and a 70MB hard drive. The N16R8 clock speed, RAM, and flash are all within an order of magnitude of what was on that old PC. https://github.com/ESP32DE/Boot-Linux-ESP32S3-Playground

ESP32 Bus Pirate is an open-source firmware that turns your device into a multi-protocol hacker's tool, inspired by the legendary Bus Pirate. It supports sniffing, sending, scripting, and interacting with various digital protocols (I2C, UART, 1-Wire, SPI, etc.) via a serial terminal or web-based CLI. Modes for: - HiZ (default) - I2C (scan, glitch, slave mode, dump) - SPI (flash, sdcard, slave mode) - UART / Half-Duplex UART (bridge, read, write) - 1-WIRE (ibutton, temp sensor) - 2WIRE (smartcard) / 3WIRE (eeprom) - DIO (Digital I/O, read, pullup, set) - Infrared (device-b-gone, send and receive) - USB (HID, mouse, keyboard, gamepad, storage) - Bluetooth (BLE HID, scan, spoofing, sniffing) - Wi-Fi (scan, AP, connect, sniff, deauth) - JTAG (scan pinout, SWD) - LED control (animations, set LEDs) - I2S - CAN https://github.com/geo-tp/ESP32-Bu
