Discover the best Open Source RTOS solutions for embedded systems and IoT devices
Noodle is a lightweight neural network inference engine designed to bring machine learning to resource-constrained microcontrollers like the Arduino Uno, Mega, and ESP32. By streaming activations and weights from external storage such as SD cards or flash memory, Noodle bypasses the typical RAM limitations that often prevent low-tier MCUs from running complex models.
A multi-modal robotic control system that translates spoken commands into physical actions using an ESP32-S3 for audio capture and an Arduino UNO for motor execution. The project integrates high-level AI services including Deepgram for transcription, GPT-4o for intent analysis, and 60db for text-to-speech feedback.
OpenC6 BIOS is an advanced modular firmware platform for the ESP32-C6 RISC-V microcontroller that implements a PC-like architecture by decoupling hardware initialization from application logic. Built on FreeRTOS and the ESP-IDF framework, it provides a standardized System Call Interface (ABI) for executing bare-metal payloads, a management engine running on the LP-Core coprocessor, and support for network-based booting and OTA updates.
A comprehensive guide and project for designing custom STM32H573-based PCBs, moving from schematic capture in KiCad to firmware development with STM32CubeIDE. It details essential hardware requirements like power regulation, external oscillators for USB, and 4-layer PCB stackups for signal integrity.
FlipDeFlock is a specialized counter-surveillance and site survey tool for the Flipper Zero that utilizes an external ESP32 module for advanced wireless monitoring. It provides passive detection of Flock Safety ALPR cameras, Bluetooth tracker monitoring, and comprehensive Wi-Fi and NFC security auditing. The project features a custom 'Net Guardian' interface for real-time threat assessment and supports signal-based device homing without the need for directional antennas.
A specialized V2X and ITS G5 message logger that utilizes the ESP32-C5 to capture IEEE 802.11p traffic at 5.9GHz. It supports GPS integration for synchronized time and positioning, logging raw data to SD cards or USB for analysis in Wireshark and CANalyzer.
An autonomous virtual aquarium firmware designed for the ESP32-2432S028R 'Cheap Yellow Display'. It features a stylized dot-grid renderer, simulated aquatic life, and automatic backlight adjustment using onboard sensors.
Periscope-OS is a passive 2.4GHz RF spectrum analyzer and signals intelligence tool for the M5Stack M5StickS3. It utilizes the ESP32-S3's promiscuous mode for deep packet inspection of 802.11 frames, featuring a sonar-style radar UI and IMU-based spatial tracking. The project leverages SPIFFS for telemetry logging and the M5Unified library for hardware abstraction.
