Description:

LoRa integrated LoRa Module Ra-02, designed and produced by Ai-Thinker. On the board has some extra space left over, so we give you a prototyping area, it's great for adding on your customized circuit working with the LoRa Module.

LoRa enables long-range transmissions (more than 10 km in rural areas) with low power consumption,The technology is presented in two parts: LoRa, the physical layer and LoRaWAN (Long Range Wide Area Network), the upper layers.

LoRa and LoRaWAN permit long-range connectivity for Internet of Things (IoT) devices in different types of industries.

  • Lora Module: Ra-02 (by Ai-Thinker)
  • Series Communication Protocol: SPI
  • Universal Perboard
  • Working Frequency: 433 MHz
  • Supports FSK, GFSK, MSK, GMSK, LoRa ™ and OOK modulation modes
  • Receive sensitivity: lowest to -141 dBm
  • Programmable bit rate up to 300Kbps
  • Build-in PCB Antenna
  • External Antenna port
  • Program platform: Arduino, Mrcropython, UIFlow(Blockly)
  • Product Size: 54.2mm x 54.2mm x 12.8mm
  • Product weight: 14.5g

Package Include:

  • 1x M5Stack LoRa Module

Applications:

  • Automatic meter reading
  • Home building automation
  • Remote irrigation system

EasyLoader

1.EasyLoader is a simple and fast program burner, and each product page has a product-related case program for EasyLoader.

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

Example:

for Arduino IDE

These are the point-to-point communication examples 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.
