Summary
Creator Magic’s Mike tests whether Google’s newest model, Gemini 4 Argon, can write firmware for hardware that has not yet been released. The board is the ESP Mosao, a pre-release device from Espressif built around the new ESP32-S31 chip and designed for AI coding agents from day one.
The hardware includes Wi-Fi 6, Bluetooth, 16 MB of memory, a 480×480 touchscreen, speaker, microphone, vibration motor, gyroscope, camera and a built-in battery. Magnetic edges let modules snap on, such as RGB LEDs, motion and light sensors, and an infrared blaster. The board ships with a chat-coding mode, and Espressif’s GitHub repository includes agent-oriented documentation and a simulator that lets an agent screenshot the device to check its own work.
Mike gives Gemini the board’s API reference, a working network module and a starter project, with a strict instruction to use only what is documented. The task is a live dashboard showing his three AI trading bees, with colored cards, LEDs that turn green or red, and a screen that wakes when motion is detected. Gemini produced a roughly 2 MB firmware build that compiled cleanly. The video then follows the difficult part: getting the board into recovery mode to flash it, which the AI helped solve by reading the documentation.
