Arduino CLI build PlatformIO build

Easily create home automation scenarios and sensor networks

Updated 2023:

RF24Ethernet requires the RF24, RF24Network and RF24Mesh libraries

Documentation & Setup Info: http://nRF24.github.io/RF24Ethernet

Downloads: http://tmrh20.github.io/

Note: Recent changes to support NRF5x boards prevent usage of RF24 devices with NRF5x boards. Users must use the internal radio with RF24Ethernet. See the nrf_to_nrf Arduino library.
