Elecrow ESP32 Wi-Fi HaLow Module with 2MP Camera | 32Mbps High Speed | Long-distance transmission-915MHz

Wi-Fi HaLow (based on the IEEE 802.11ah) is a low-power, long-range wireless communication technology designed by the Wi-Fi Alliance specifically for IoT scenarios. Compared to traditional Wi-Fi technology, it operates in the Sub-1 GHz unlicensed frequency band (mainly the 900MHz band). This frequency offers stronger diffraction and penetration, enabling it to effectively pass through buildings, vegetation, and other obstacles, thereby overcoming the inherent limitations of traditional Wi-Fi in coverage and environmental penetration.

The ESP32 Wi-Fi HaLow camera module is a product that breaks through the limitations of traditional wireless communication distance. Based on the ESP32-S3 and IEEE 802.11ah (Wi-Fi HaLow) technology, it is designed specifically for long-range, high-speed IoT applications. It solves the pain points of traditional Wi-Fi, such as poor wall penetration and short coverage, while also overcoming the shortcomings of LoRa, such as low speed and inability to transmit video. Theoretically, it supports a transmission distance of over 1 kilometer and speeds up to 32 Mbps, making it ideal for IoT applications requiring reliable, high-performance connectivity.

The module integrates a 2-megapixel camera (supporting automatic exposure/gain, image scaling and compression, etc.), an SD card slot, a Type-C interface, and triple wireless connectivity (Wi-Fi + Bluetooth + Wi-Fi HaLow). It features a low-power design and strong signal penetration. Supporting the Arduino development environment, it is an ideal platform for makers and IoT engineers to explore long-range wireless communication.

Datasheet

Features

• Long-distance, high-speed transmission: Based on Wi-Fi HaLow (IEEE 802.11ah) technology, operating in the Sub-1GHz band, it theoretically achieves a transmission distance of 1-2 km, while supporting a maximum data transmission rate of 32 Mbps, balancing long-distance transmission with video-level data throughput.
• Strong penetration and low power consumption: Low-frequency radio waves have excellent penetration capabilities, effectively passing through obstacles such as walls and trees; its low-power design makes it suitable for outdoor deployment.
• Integrated HD Camera: Features an onboard 2MP camera with automatic exposure control, automatic gain control, image scaling, and compression. It can capture and transmit video images in real-time over long distances, suitable for security monitoring, remote inspection, and other scenarios.
• Triple Wireless Connectivity: Simultaneously integrates 2.4GHz Wi-Fi, Bluetooth Low Energy, and Wi-Fi HaLow, meeting diverse needs for local debugging, short-range interaction, and long-range networking; a reserved IPEX (U.FL) interface facilitates the connection of external high-gain antennas to further enhance signal coverage.
• Abundant Storage and Interfaces: Onboard SD card slot supports local data storage and offline deployment; utilizes a Type-C USB interface, integrating a voltage regulator, ESD protection, short-circuit protection, and RF shielding to ensure stable operation in complex environments.
