The author demonstrates how to run Espressif's ESP-Claw agent framework on an ESP32-P4 microcontroller using a self-hosted Qwen 3.6 LLM. Unlike standard TinyML implementations that only use microcontrollers for simple tasks, this setup allows the chip to manage sensing, decision-making, and tool execution through Lua scripts triggered via Telegram. The project shows how hardware behavior can be modified in real-time through chat without needing to recompile firmware.
Main topics:
* Implementation of an agent loop directly on a microcontroller
* Using Lua modules for dynamic runtime skill acquisition
* Interfacing with LLMs via OpenAI-compatible APIs
* Controlling peripherals like GPIO, I2C, and sensors through natural language
* Utilizing Telegram as the primary user interface

Anthropic has released an open-source project called Claude Desktop Buddy that allows ESP32-S3 hardware to act as a physical companion for the Claude desktop application. By utilizing a new Bluetooth Low Energy (BLE) API, these small devices can provide real-time updates on AI agent activity and allow users to approve or deny permission requests directly through physical buttons.
Key features and details:
- Connects via BLE to macOS and Windows desktop apps for fast, local interaction
- Features Tamagotchi-style animations that reflect the AI's status, such as sleep, busy, or attention modes
- Supports custom character skins using user-provided GIF packs
- Optimized for ESP32-S3 boards like the M5StickC Plus and M5Stack Cardputer
- Developed using the Arduino framework and PlatformIO

Clawdmeter is a custom-built desk dashboard powered by the ESP32-S3 that provides real-time monitoring of Claude Code token usage. Utilizing a 2.16-inch AMOLED screen and Bluetooth LE connectivity, the device displays animated pixel art that reacts to usage rates and acts as a HID keyboard for quick command shortcuts via BLE.
Victor Frost has created an ESP32-based community hub that functions as a localized message board with a solarpunk aesthetic. The device resembles a lantern and operates as a local webserver accessible through its own wireless captive portal. It is powered by solar energy using 18650 battery cells. To facilitate easy updates, the project utilizes LittleFS for flash partitioning and stores the entire user interface in PROGMEM rather than on a file system.
Espressif Systems has introduced the ESP-Claw framework, designed to enable ESP32 devices to function as local AI agents. The framework allows hardware to interact with Large Language Models (LLMs) to make decisions and execute actions locally without requiring constant cloud connectivity. It supports natural language conversation for defining device behavior through chat coding and utilizes Lua scripts for deterministic execution.
Key features include:
- Local event bus driving millisecond-latency responses via Lua rules.
- MCP Server and Client capabilities for hardware exposure and external service calling.
- On-chip private memory for long-term context retention without data leaving the device.
- Support for various messaging platforms including Telegram, WeChat, and Feishu.
- Compatibility with LLMs such as OpenAI, Qwen, and ChatGPT.
- Current support for ESP32-S3 with upcoming support for ESP32-P4.
