433MHz Lora RA-02 was developed by the company Ai-Thinker. Lora Ra-02 module is designed using SX1278 IC base and works on 433MHz frequency. Frequency hopping-which gives you a sweet balance of quality signal transmission – will cover the range 420-450MHz. With this remote wireless capability the module is packed into a small package (17 x 16mm).
This 433MHz RA-02 Lora (Long Term Radio) 433MHz module will take your IoT project distance from communications via the remote deployment spectrum. This form of wireless communication generates greater bandwidth, improves interference resistance, minimizes current consumption, and enhances security. By using Lora Ra-02 module, you do not need to compromise in balance range, immune disorder, or energy consumption. The technology behind this SX1278 IC means it is suitable for projects that require range and power.
Lora Ra-02 Features:
- LoRaTM spread spectrum communication.
- +20dBm – 10mW. Stable RF output power when input voltage changed.

433MHz Lora Ra-02 Eagle PCB Libary.
A few days ago I bought Lora Ra-02 module through Amazon, but after module Lora Ra-02 I received, there are constraints to design PCB board for Lora Ra-02 module by using Eagle PCB software. After searching the search engine and finding no results, I decided to create your own Egle PCB library module for Lora Ra-02 module with SMD model and the result as shown below.
