Description

AtomS3R-CAM is a mini IoT programmable controller with an integrated camera. It is powered by the ESP32-S3-PICO-1-N8R8 SoC featuring Wi-Fi connectivity, 8MB on-chip Flash, and 8MB PSRAM. The unit carries a 5 V-to-3.3 V power-management circuit, a three-axis BMM150 geomagnetic sensor, and a six-axis BMI270 IMU. In addition, it is equipped with a 0.3 MP GC0308 camera that supports image acquisition and infrared transmission control. Protective glass is fitted in front of the camera to keep dust out and enhance image quality. Compared with previous products, the 3D antenna of AtomS3R-CAM has been enhanced to deliver higher performance and stability.

The factory firmware supports UVC (USB Video Class), allowing the device to work as a driver-free USB camera—simply connect via USB and use it directly. The product also features a USB Type-C port for power supply and firmware download, plus a HY2.0-4P expansion port. Six GPIOs and power pins are exposed on the bottom for further expansion. With compact dimensions of 24.0 x 24.0 x 13.5 mm, it is well suited for IoT monitoring, educational development tools, and other embedded scenarios.
