LoRa Radio Module - 433MHz

The LoRa MESH Radio Module is a powerful and energy-efficient micro-power RF module designed for long-range communication. It utilizes a distributed ad-hoc network communication mode and incorporates embedded wireless MESH MANET protocols. The module offers seamless integration with existing devices and protocols without requiring any modifications or secondary development. With this module, users can effortlessly establish wireless ad-hoc networks.

The module employs advanced RF chip technology based on spread spectrum frequency hopping, spread spectrum calculations, and integrated automatic CRC error correction processing. As a result, it outperforms other module types in terms of stability, anti-interference capability, and receive sensitivity.

Additionally, the module supports multiple modes including API mode, transparent mode, and AT command mode. Users can easily configure the module by utilizing our PC software or by sending AT commands through a microcontroller. This flexible configuration allows users to adapt the module based on their specific requirements, making it user-friendly and easily accessible.

For convenient parameter setting, we recommend using a USB to TTL Converter. This converter facilitates seamless communication with the module and simplifies the process of adjusting its settings. Furthermore, the Gravity IO Expansion Shield is directly compatible with Lora modules, enabling hassle-free integration and expansion of functionality.
