The nRF24LU1+ combines Nordic’s nRF24L01+ 2.4GHz radio transceiver with the nRF24LU1 USB dongle single chip device.
This solution includes an integrated voltage regulator that allows the chip to be powered directly from a USB bus, removing the requirement for an external voltage regulator.
In addition, on-chip flash memory eliminates the need for an external E2PROM memory. The only external components the nRF24LU1+ chip requires are a low cost 16MHz crystal, decoupling, matching network and antenna.
