## What it is
An optimized C++ driver library for the nRF24L01(+) 2.4GHz wireless transceiver, acting as an OSI Layer 2 radio driver. It supports Arduino, Raspberry Pi/Linux, and RP2xxx platforms with a beginner-friendly API and extensive examples.

## Use cases
- wirelessly connect Arduino sensors to a Raspberry Pi
- build a home sensor network with nRF24L01 modules
- stream data between microcontrollers over 2.4GHz radio
- drive nRF24L01+ transceivers from Linux SBCs
- create low-power wireless communication between embedded devices

## When to choose
- you use nRF24L01(+) radio modules with Arduino, Raspberry Pi, or RP2xxx hardware
- you want a well-documented, actively maintained driver with rich examples
- you need reliable, high-speed layer 2 radio communication

## When to avoid
- you need TCP/IP or mesh networking out of the box (see RF24Network/RF24Mesh/RF24Ethernet)
- your radio hardware is NRF52x rather than nRF24L01 (consider nrf_to_nrf)
- you need a higher-level networking stack rather than a raw radio driver

## Facets
