AtomS3R M12

SKU:C126-M12

Description

AtomS3R M12 is an IoT programmable controller integrated with an M12 camera, featuring a 3-megapixel OV3660 Wide Angle camera that supports high-resolution image capture. It uses the ESP32-S3-PICO-1-N8R8 as the main controller, with built-in WiFi functionality, 8MB onboard FLASH, and 8MB PSRAM. It includes a power management circuit that converts 5V to 3.3V and has an embedded three-axis BMM150 geomagnetic sensor and a six-axis BMI270 motion sensor. The product comes with UVC (USB Video Class) firmware, allowing it to be used as a plug-and-play USB camera without the need for driver installation, and it also has infrared emission control.

Compared to previous ATOM series host products, the AtomS3R M12 features an enhanced 3D antenna, providing better performance and stability. The product includes a Type-C interface for power supply and firmware downloads, along with an HY2.0-4P expansion port. The bottom design features six GPIO and power pins for easy expansion. Measuring only 24x24x22.1mm, it is suitable for applications such as IoT device monitoring, educational development tools, and various embedded scenarios.

Download Mode
To flash the firmware, press and hold the reset button (for about 2 seconds) until the internal green LED lights up, then release the button. The device will enter download mode and is ready for flashing.
