Discover the best Open Source RTOS solutions for embedded systems and IoT devices
PomoDesk is an ESP32-S3-based physical Pomodoro timer designed to help users maintain a flow state while ensuring they take regular breaks. It uses a NeoPixel LED ring for visual feedback and features power-saving optimizations by disabling unused wireless radios.
Melody Machine is a feature-rich MP3 player and internet radio firmware designed for the LilyGO T-LoRa Pager (ESP32-S3). It leverages FreeRTOS for dual-core audio processing and the LVGL library to provide a responsive graphical interface with support for local microSD playback and WiFi-based streaming.
Shrike is a family of low-cost, open-source FPGA development boards paired with microcontrollers like the RP2040, RP2350, and ESP32-S3. These boards feature a Renesas FPGA with 1120 LUTs, designed to bridge the gap between embedded microcontrollers and reconfigurable logic for learners and hobbyists.
Galagino is an ESP32-based arcade emulator ported to PlatformIO, supporting 24 classic games like Galaga, Pac-Man, and Donkey Kong. It is specifically optimized for the 'Cheap Yellow Display' (CYD) and designed to be retrofitted into commercial micro-arcade cabinets using the Arduino framework on FreeRTOS.
A specialized port of the ESP32 Marauder firmware for the ESP32-3248S035C development board, featuring a 3.5-inch capacitive touchscreen. It provides mobile tools for Wi-Fi security auditing, network scanning, and wardriving, leveraging FreeRTOS and the Arduino framework for efficient hardware management.
A sophisticated physical chess board utilizing Hall effect sensors for piece detection and dual displays for game status and clock. It runs on Go-powered Raspberry Pi or Orange Pi hardware, featuring deep Lichess integration, local Stockfish analysis, and a custom DietPi-based OS image with power-loss protection.
A high-performance VGA controller built around the 8-bit PIC18F47K42 microcontroller, capable of 360x480 resolution with 16 colors. It utilizes hardware peripherals like DMA, PWM, and SPI to generate signals with minimal CPU overhead, accepting ANSI-style escape sequences over a UART interface.
Paper Pi is a modular, asynchronous dashboard designed for Waveshare E-Ink displays, built with Python 3.14+. It targets Raspberry Pi and other Linux-based boards, providing a variety of widgets such as GitHub stats, weather, and HackerNews with support for 4-level grayscale rendering.
