Reserved frequency bands are different from region to region. For example, the first LoRa click board
This LoRa module has the same firmware
LoRa 2 Click
LoRa 2 click board carries Microchip's RN2903 - long range LoRa technology transceiver. Like the first LoRa click board, this one also complies with the LoRaWAN Class A protocol specifications. More about Class A devices can be found on Lora Alliance web pages.
RN2903 operates in the 915 MHz frequency band which means it ranges from 902.0 MHz to 928.0 MHz. This module can achieve high receiver sensitivity of -146 dBm. This higher sensitivity in combination with adjustable output power,( up to +18.5 dBm ) results in a range of more than 15 km in suburban areas.
There is a choice of three different modulation
LoRa 2 can work on 3.3 or 5 Volts power supply. Typical current consumption strongly depends on the current operation mode. In
LoRa 2 Library
Therefore the only difference between LoRa click and LoRa 2 click is the frequency, and the same library can be used for both of them.
LoRa 2 board expects the same settings for the UART
- Baud Rate - 57600 bps
- Packet Length - 8 bit
- Parity Bits - No
- Stop Bits - 1 bit
- Hardware Flow Control - No
This example might give you an idea on how to implement our library inside your own application.
The whole world is covered now. LoRa click covers EU with 868 MHz and Asia region with 433 MHz
