433Mhz RA02 LoRa Module 

433 Mhz Long Range Wireless LoRA Module 

LoRa Modules are long range low power RF Modules. Great for IoT applications to send sensor data to the cloud over long ranges. 

Developed by Ai-Thinker, the manufacturer of the ESP8266 and ESP32 wifi modules, this Ra-02 LoRa (Long-range Radio) module will take your IoT projects the distance with communication over a long-range spread spectrum. This form of wireless communication results in a larger bandwidth, increasing interference resistance, minimizing current consumption, and increasing security. 

This module uses SX1278 IC from SEMTECH and works on a 433MHz frequency. Frequency hopping—which gives you that sweet balance of quality signal transmission will cover a range of 420-450 MHz. This long range wireless capability is packed into a small (17 x 16mm) package and delivered without an antenna.

With the LoRa Ra-02, you don’t have to compromise in the balance of range, interference immunity, or energy consumption. The technology behind this IC means that it's perfect for those projects requiring range and strength.
