Run OpenClaw on a $5 chip. No OS, no Node.js, no Mac mini, no Raspberry Pi, no VPS. Written in C with ESP-IDF 5.5. Controls GPIO, sensors, and actuators. 0.5W power consumption. Privacy-first, local-first memory.
Install the Espressif IoT Development Framework. This is required for ESP32-S3 development.
mkdir -p ~/esp
cd ~/esp
git clone --recursive https://github.com/espressif/esp-idf.git -b v5.5
cd esp-idf
./install.sh esp32s3
source export.shDownload the MimiClaw firmware source code.

Native target for MimiClaw. GPIO and sensor control works. Limited by 8MB PSRAM.
Use a serial monitor to debug firmware issues during initial setup.
Flash firmware over USB first, then enable OTA updates for convenience.
Keep GPIO pin assignments documented for your specific wiring setup.
