## What it is
RadioLib is a universal C++ wireless communication library for embedded devices, providing a unified API to drive many radio modules (SX127x, SX126x, SX128x, RF69, CC1101, nRF24L01, LR11x0, etc.). It also implements digital modes and protocols such as LoRaWAN, AX.25, APRS, RTTY, SSTV, Morse, and Hellschreiber.

## Use cases
- send LoRa packets from an ESP32 with an SX1278 module
- build a LoRaWAN node on a microcontroller
- transmit RTTY or SSTV using a cheap radio module
- implement APRS or AX.25 packet radio on Arduino
- drive an nRF24L01 or CC1101 from embedded C++
- port radio drivers to a non-Arduino embedded platform

## When to choose
- you need one consistent API across many different radio transceiver chips
- you want LoRa/FSK plus legacy digital modes like RTTY, APRS, or Morse on a microcontroller
- you're building IoT or amateur radio projects on Arduino or bare-metal embedded targets

## When to avoid
- you need WiFi, cellular, or TCP/IP networking rather than sub-GHz/2.4 GHz radio modules
- you want a high-level LoRaWAN network server or cloud IoT platform rather than a device-side driver
- your project targets desktop or server platforms without microcontroller hardware

## Facets
