The AtomS3R-M12 camera controller is a compact IoT programmable controller with an integrated M12 camera. It uses the ESP32-S3-PICO-1-N8R8 SoC with 2.4 GHz Wi-Fi, 8MB Flash, and 8MB PSRAM, providing a small platform for high-resolution image capture and connected embedded applications.

The AtomS3R-M12 camera controller includes a 3 MP OV3660 wide-angle camera, BMI270 6-axis IMU, BMM150 3-axis geomagnetic sensor, infrared transmission control, USB Type-C, HY2.0-4P expansion, and bottom GPIO access. Factory firmware supports UVC and Wi-Fi image transmission, allowing direct USB camera use or browser-based preview through the device access point.

Warning: Products containing magnets may interfere with the BMM150 magnetic field sensor and cause abnormal readings. When used with a controller that contains a magnet, remove the magnet and keep the BMM150 sensor away from strong magnetic fields.
