Discover the best Open Source RTOS solutions for embedded systems and IoT devices
A single-button wireless keyboard built on the ESP32-C5 that translates Morse code patterns into HID keystrokes over Bluetooth Low Energy. It features a real-time LVGL UI on a tiny 0.85-inch display and implements secure BLE bonding using the NimBLE stack.
An AI companion robot project for the M5Stack AtomS3R that connects an ESP32-based body to local AI services. It supports speech recognition, local LLM chat, and text-to-speech integration while providing a hardware interface for sensors and servos.
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.
