M5Stack ATOMS3R Camera Kit (8MB PSRAM)OpenELAB

Description

AtomS3R Cam is a mini programmable controller integrated with a camera, featuring the ESP32-S3-PICO-1-N8R8 main controller with built-in WiFi, 8MB onboard FLASH, and 8MB PSRAM. It includes a power management circuit that converts 5V to 3.3V, along with a built-in three-axis BMM150 geomagnetic sensor and six-axis BMI270 attitude sensor. Additionally, the product is equipped with a 0.3MP GC0308 camera, supporting image capture and infrared transmission control. The camera is protected by a glass cover to prevent dust and improve image quality. Compared to previous products, the 3D antenna of the AtomS3R Cam has been enhanced, offering improved performance and greater stability. The product comes pre-installed with UVC (USB Video Class) firmware, allowing it to function as a driver-free USB camera. Users can use the camera directly via the USB interface without installing any drivers. The product also includes a Type-C interface for power supply and firmware downloads, and features a HY2.0-4P expansion port. Six GPIO and power pins are reserved at the bottom for easy expansion. With a compact size of 24x24x13.5mm, it is suitable for embedded scenarios such as IoT device monitoring and educational development tools.
