🧩 AtomS3R M12 is a compact and powerful ESP32-S3-based IoT controller featuring a high-resolution 3MP OV3660 camera for smart vision applications. It integrates the ESP32-S3-PICO-1-N8R8 chip with built-in Wi-Fi, 8MB Flash, and 8MB PSRAM.
📷 With UVC (USB Video Class) firmware, AtomS3R M12 functions as a plug-and-play USB camera — no drivers required. It also supports infrared emission control and includes a 9-axis sensor system (six-axis BMI270 + three-axis BMM150 geomagnetic sensor).
⚙️ Compared to previous ATOM series, AtomS3R M12 features an upgraded 3D antenna for improved wireless performance. It offers a Type-C interface for power and firmware updates, an HY2.0-4P expansion port, and six GPIO + power pins for easy integration. Its ultra-compact size (24×24×22.1mm) makes it ideal for IoT monitoring, wearables, and embedded development.
