# Module LoRa (433MHz)
SKU:M005
## Description
**LoRa (433MHz)** is a LoRa communication module in the M5Stack stack module series (working frequency is 433MHz). A certain expansion space is reserved on the module, which defeats you for more functional design. For wireless communication or projects with more customized elements, the LoRa (433MHz) module will be a suitable choice.

>1.EasyLoader is a simple and fast program burner. Every product page in EasyLoader provides a product-related case program. It can be burned to the master through simple steps, and a series of function verification can be performed.
>2.After downloading the software, double-click to run the application, connect the M5 device to the computer via the data cable, select the port parameters, and click **"Burn"** to start burning.
>3.The CP210X (USB driver) needs to be installed before the EasyLoader is burned. [Click here to view the driver installation tutorial](en/related_documents/M5Burner#install-usb-driver)
## Example
### 1. Arduino IDE
These are the point-to-point communication [examples](https://github.com/m5stack/M5Stack/tree/master/examples/Modules/LoRa433_SX1278) between two LORA modules. The LoRa nodes send and receive messages.
* Blue string indicates sending succeed.
* Yellow string display the received messages.
* Red string indicates initialization failed.
