## What it is
An Arduino library for sending and receiving data over LoRa radios using Semtech SX1276/77/78/79-based modules. It provides a simple API for configuring frequency, pins, and packet transmission/reception on compatible hardware.

## Use cases
- send sensor data over long range with LoRa radios
- build an Arduino LoRa transmitter or receiver
- communicate between Arduino boards using RFM95W modules
- use a Dragino LoRa shield with Arduino
- receive LoRa packets with interrupt callbacks
- prototype low-power long-range IoT communication

## When to choose
- you use Semtech SX127x-based modules like RFM95W or Dragino shields with Arduino
- you want a simple, well-documented API for raw LoRa packet communication
- you need a lightweight library installable via the Arduino IDE Library Manager

## When to avoid
- you need LoRaWAN protocol support with network join and OTAA/ABP
- you use an Arduino MKR WAN 1300 and rely on receive callbacks, which are unsupported
- your project targets non-Semtech LoRa chipsets

## Facets
- artifact type: library
- maturity: maintenance
- function: sdk, networking, embedded
- domain: iot, embedded-systems, hardware
- platform: embedded, iot, cpp
- tags: lora, arduino, radio, sx127x, wireless, long-range-communication
