LORA MODULE 433MHZ 10KM RA-02 AI-THINKER WIRELESS TRANSMISSION

Description :

The LoRa Module 433MHz 10km RA-02 from AI-Thinker is a wireless transceiver module designed for long-range data transmission over a low power network. The module operates on the unlicensed 433 MHz frequency band and uses the LoRa spread-spectrum modulation technology to achieve long-range wireless communication. Here's a brief description of the module:

The RA-02 LoRa Module features a compact size and low power consumption, making it ideal for IoT applications, remote monitoring, and other wireless communication projects. It has a maximum transmission range of up to 10km in open space and can communicate with other LoRa devices, gateways, or networks.

The module has a built-in SX1278 LoRa chip and an SPI interface for communication with a microcontroller or other devices. It supports a wide range of data rates, from 300 bps to 37.5 kbps, and provides a high receiver sensitivity of -138 dBm. The module has a voltage range of 1.8V to 3.7V and consumes only a few microamps in sleep mode, making it suitable for battery-powered applications.

The RA-02 LoRa Module is easy to use and comes with a pre-programmed firmware that supports a simple AT command interface for configuration and control. It also includes an onboard spring antenna, but it can be replaced with an external antenna for better range and performance.

Overall, the RA-02 LoRa Module is a reliable and affordable solution for long-range wireless communication, which can be used in a variety of applications such as remote monitoring, telemetry, asset tracking, and smart city infrastructure.
