Discover the best Open Source RTOS solutions for embedded systems and IoT devices
An open-source DC uninterruptible power supply designed specifically for the Raspberry Pi 5, featuring triple-input power paths and smart battery management. It utilizes a dual-MCU architecture with a CH32X035 for power delivery and an RP2040 for the user interface, while supporting remote monitoring via FreeRTOS and the lwIP stack.
FOC Ears is an open-source animatronics project designed to create silent, high-performance cat ears using Field Oriented Control (FOC). Built on an ESP32 microcontroller, it utilizes brushless gimbal motors and magnetic encoders to achieve smooth, quiet motion compared to traditional RC servos. The system integrates an IMU for orientation sensing and is developed using the PlatformIO environment.
An advanced Morse code keyer based on the K3NG project, ported to ESP32 and Raspberry Pi Pico 2W hardware. It features integrated Bluetooth keyboard support, high-resolution TFT touch displays, and GPS-based location tracking, utilizing dual-core processing to maintain precise keying timing.
NRSuite is a modular wireless research toolkit that offloads the radio layer to an ESP32 connected via USB OTG to an unrooted Android device. It enables advanced Wi-Fi operations, BLE HID emulation, and BadUSB functionality within the Termux environment using a custom binary bridge protocol.
RisalDash is a C++ library for ESP32 and ESP8266 that automatically generates real-time web dashboards with zero front-end coding. It features a zero-waste architecture to minimize flash usage, built-in captive portal provisioning, and native integration with Home Assistant and AI agents via the Model Context Protocol (MCP).
An ESP32-based monitoring hub for the 'Cheap Yellow Display' (CYD) that tracks weather, space events, wildfires, and geological activity. It features a custom power management system called Somnus for instant-wake deep sleep and includes a robust calibration system to support various hardware revisions.
LuxDMX is an open-source Art-Net and sACN to DMX512 gateway designed for ESP32 and ESP32-S3 microcontrollers, featuring a live web-based diagnostic interface. It provides professional-grade lighting control with support for RDM, source merging (HTP/LTP), and multiple network interfaces including WiFi and wired Ethernet. The project utilizes a FreeRTOS-based architecture to ensure low-jitter DMX timing while simultaneously serving high-speed telemetry via WebSockets.
An Arduino Nano-based interface designed to enhance the control and safety of dual-track vehicles using inexpensive BLDC motor controllers. It replaces standard filtered PWM with a high-resolution 12-bit DAC and implements configurable drive profiles, throttle shaping, and track trim compensation.
