Description The AtomS3R-CAM camera controller is a compact programmable IoT controller with an integrated 0.3 MP GC0308 camera. It is built around the ESP32-S3-PICO-1-N8R8 SoC with 2.4 GHz Wi-Fi, 8MB Flash, and 8MB PSRAM for camera capture, local control, and connected embedded applications. In addition to image acquisition, the AtomS3R-CAM camera controller integrates a BMI270 6-axis IMU, BMM150 3-axis geomagnetic sensor, infrared transmission control, USB Type-C, HY2.0-4P expansion, and exposed bottom GPIO pins. Factory firmware supports UVC, so the device can work as a driver-free USB camera when connected by USB. Warning: Products containing magnets may interfere with the BMM150 magnetic sensor and cause abnormal readings. When used with controllers that include magnets, remove the magnets and keep the BMM150 away from strong magnetic fields. Features ESP32-S3-PICO-1-N8R8 SoC with Wi-Fi, 8MB Flash, and 8MB PSRAM. 0.3 MP GC0308 camera with glass front panel and 30 fps maximum frame rate. 9-axis sensing system with BMI270 6-axis IMU and BMM150 geomagnetic sensor. Supports infrared transmission control, UVC USB camera mode, and Wi-Fi video workflows. AtomS3R-CAM camera controller design with USB-C, HY2.0-4P expansion, and bottom GPIO access.
