The nRF24E1 is a nRF2401 2.4GHz radio transceiver with an embedded 8051
compatible microcontroller and a 10-bit 9 input 100 kSPS AD converter. The circuit
is supplied by only one voltage in range 1.9V to 3.6V. The nRF24E1 supports the
proprietary and innovative modes of the nRF2401 such as ShockBurstTM and
DuoCeiverTM.
