Description
AtomS3R-M12 is an IoT programmable controller integrated with an M12 camera, equipped with a 3-megapixel OV3660 wide-angle camera, supporting high-resolution image capture. It uses the ESP32-S3-PICO-1-N8R8 as the main controller, integrating Wi-Fi functionality, 8MB on-chip Flash, and 8MB PSRAM. It features a 5V to 3.3V power management circuit and includes a three-axis BMM150 geomagnetic sensor and a six-axis BMI270 attitude sensor. The product comes with UVC (USB Video Class) firmware, allowing it to be used as a driver-free USB camera, enabling users to use the camera directly via USB without installing drivers, and it has infrared emission control functionality. Compared to previous ATOM series host products, the 3D antenna of AtomS3R-M12 is enhanced, providing better performance and higher stability. The product also includes a USB Type-C interface for power supply and firmware download, and features a HY2.0-4P expansion port. The bottom is designed with six GPIO and power pins for easy expansion. With dimensions of only 24.0 x 24.0 x 22.1mm, it is suitable for embedded scenarios such as IoT device monitoring and educational development tools.
