The AtomS3R M12 is an IoT programmable controller integrated with a 3-megapixel OV3660 camera, supporting high-resolution image capture. The AtomS3R M12 employs the ESP32-S3-PICO-1-N8R8 as its principal controller, offering integrated WiFi, 8MB of onboard flash memory, and 8MB of PSRAM. The device includes a power management circuit that converts 5V to 3.3V and is equipped with a three-axis BMM150 geomagnetic sensor and a six-axis BMI270 motion sensor, both of which are integrated into the main circuitry. With UVC (USB Video Class) firmware, the device functions as a plug-and-play USB camera, eliminating the need for driver installation. Additionally, it supports infrared emission control.
In comparison to previous ATOM series products, the AtomS3R M12 features an enhanced 3D antenna, which offers improved performance and stability. The device features a Type-C interface for power supply and firmware downloads, along with an HY2.0-4P expansion port. The bottom design includes six GPIO and power pins for easy expansion. Its compact dimensions (24x24x22.1mm) make it ideal for IoT device monitoring, educational development tools, and various embedded applications.
