Let an AI model use a real iPhone with a $7 ESP32: AirPlay eyes, USB HID hands, any OpenAI-compatible vision model. No Mac, no developer account, no jailbreak.

Turn ordinary WiFi into a spatial intelligence / sensing system. Detect people, measure breathing and heart rate, track movement, and monitor rooms — through walls, in the dark, with no cameras or wearables. Just physics.

OOMWOO is an open-source home robot vacuum you can build yourself, built using Raspberry Pi, 3D-printing, Home Assistant, Arduino and ROS2. It uses an affordable 2D LiDAR to map your home and navigate on its own.

For beginners, it is recommended to use the firmware that can be flashed without setting up a development environment.

The trick everyone misses: you don't need to keep the blocklist in RAM. Store the domains as sorted 40-bit hashes in flash and binary-search them. 7 MB of flash and are matched in 10 ms, using 50 KB of RAM.

A simple and easy-to-use library to enjoy videogames programming

Muse gadgets are open source devices you build yourself. Program an off-the-shelf ESP32 board or set up a Raspberry Pi with our device SDKs, then connect Muse to your displays, buttons, sensors, actuators, and whatever else you've got lying on your workbench.

4 GHz Wi-Fi radio into a software-defined radio (SDR). It lets you capture the radio signal itself and process it in software, so you can view the spectrum and study signals beyond ordinary Wi-Fi packets. No separate SDR hardware is needed.

The ultimate harness for coding agents and beyond. All your agents. All your machines.

Sesame is an accessible Open-Source robotics project based on the ESP32 microcontroller system, with an emphasis on expression and movement. This project is designed for makers and engineers of all skill levels!

A Hardware Hacking Tool with Web-Based CLI That Speaks Every Protocol

LVGL is a free, full-featured embedded UI library for devices from small MCUs to 3D-capable MPUs, enhanced by LVGL Pro, a professional editor and tooling.

本项目为xiaozhi-esp32提供后端服务，帮助您快速搭建ESP32设备控制服务器。Backend service for xiaozhi-esp32, helps you quickly build an ESP32 device control server.

CrossPoint is open-source e-reader firmware - community-built, fully hackable, free forever. It's maintained by a growing community of developers and readers who believe your device should do what you want - not what a manufacturer decided for you.

Omi captures your screen and conversations, transcribes in real-time, generates summaries and action items, and gives you an AI chat that remembers everything you've seen and heard. Works on desktop, phone and wearables. Fully open source.

A suite of WiFi/Bluetooth offensive and defensive tools for the ESP32

9 million parameter language model that generates text on an ESP32-S3 microcontroller. 88 tokens per second on a small screen wired to the chip. It fits because most of the model lives in flash instead of RAM, using Per-Layer Embeddings, an idea from Google's Gemma 3n.

Espressif IoT Development Framework. Official development framework for Espressif SoCs.

ArduPilot is the most advanced, full-featured, and reliable open source autopilot software available. It has been under development since 2010 by a diverse team of professional engineers, computer scientists, and community contributors.

A brushless gimbal motor is paired with a magnetic encoder to provide closed-loop torque feedback control, making it possible to dynamically create and adjust the feel of detents and endstops.

Tiny Engineer is an open-source, 3D-printable desktop robot that physically acts out what an AI coding agent is doing: reading, thinking, coding, finishing tasks. It runs on an ESP32 over Wi-Fi and exposes a simple REST API, so any tool that can make an HTTP request can drive it.

Marlin is a firmware for RepRap 3D printers optimized for both 8 and 32 bit microcontrollers. Marlin supports all common platforms. Many commercial 3D printers come with Marlin installed.

Hand-picked ESP32 projects worth building, copying, or watching run

TinyGo is a Go compiler intended for use in small places such as microcontrollers, WebAssembly (wasm/wasi), and command-line tools.

Our Development is fully tracked on this public Roadmap 🎉

Build voice and text devices for your Hermes Agent, with ESP32 firmware, a Linux client, and a desktop simulator.

PixelFont is a family of AdafruitGFX & u8g2 compatible fonts, hand crafted for tiny low-res displays. The fonts are designed to be slender and condensed to fit as much text on a line as possible. And to also look awesome.

Jet is a dependency-free, fixed-function 3D software rasteriser written in C++17. It targets embedded hardware with limited CPU and memory, including ESP32 and STM32, and also runs on desktop PCs and Raspberry Pi.

In light of current events we like to support the people behind PlatformIO Project, especially Ivan Kravets, and wish them the strength to help stop the war. See platformio-is-ukrainian-project-please-help-us-stop-the-war for what you can do.
