Discover the best Open Source RTOS solutions for embedded systems and IoT devices
A specialized collection of fonts and utilities designed to add Ukrainian character support to popular Arduino graphics libraries like Adafruit GFX and TFT_eSPI. It includes a variety of serif, sans-serif, and monospace typefaces along with a conversion function to handle UTF-8 string encoding for embedded displays.
ESP32 Bit Pirate is an open-source firmware that transforms ESP32-S3 development boards into multi-protocol hardware hacking tools. It provides extensive support for digital protocols like I2C, SPI, and UART, as well as radio communications including Wi-Fi, Bluetooth, and Sub-GHz, utilizing FreeRTOS and LittleFS for robust device interaction.
An automated irrigation system built with ESPHome for the M5Stack AtomS3-Lite and Unit Watering modules. It supports up to six plants via I2C expansion and features moisture-based automation and safety limits through Home Assistant integration.
BETTA HA Panel is a runtime-configurable Home Assistant dashboard firmware for ESP32-P4 and ESP32-S3 touchscreen devices. Built on the ESP-IDF framework using LVGL and LittleFS, it allows users to design complex, multi-page layouts via a web-based drag-and-drop editor without requiring YAML configuration or firmware rebuilds.
Claude Buddy Pico is a hardware mascot for Claude Desktop, ported from the original M5Stack version to the Raspberry Pi Pico 2 W. It features a 2.8-inch landscape display, Bluetooth Low Energy connectivity via BTstack, and physical buttons for approving or denying AI tool calls. The project utilizes the Pimoroni Pico library for peripheral management and includes custom 3D-printable CAD files for the enclosure.
An expressive AI desk companion based on the Seeed Xiao ESP32-S3 that features a fully animated face system. It utilizes the ESP-IDF framework with FreeRTOS, LVGL for rendering display interfaces, and SPIFFS for asset storage. The project integrates I2S audio components for listening and speaking capabilities, creating a dynamic interactive experience.
A custom bootloader for the ESP32 that enables switching between multiple firmware versions using hardware switches. It integrates Over-The-Air (OTA) update capabilities and the ESP-Serial-Flasher library to facilitate remote firmware management and master-slave device flashing.
A real-time monitoring tool for Claude Code usage, designed for the ESP32-2432S028R (CYD) hardware. The project uses a Go-based daemon to track Anthropic API rate limits and displays animated pixel art sprites that react to the user's coding activity.
