MimiClaw
An OpenClaw-style personal agent on a $5 ESP32-S3 chip.
MimiClaw runs a personal AI assistant directly on an ESP32-S3 microcontroller in pure C, with no Linux or Node.js. Users message it over Telegram; the board receives the message via WiFi, runs an agent loop in which the LLM calls tools and reads local memory, and replies. It supports Anthropic and OpenAI as runtime-switchable providers, keeps memory across reboots and draws about 0.5 W from USB power. It is an example of a minimal embedded agent harness.
