The nRF24E2 is the transmitter part of the nRF2401 2.4GHz radio transceiver plus an
embedded 8051 compatible microcontroller plus 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
nRF24E2 supports the proprietary and innovative modes of the nRF2401 such as
ShockBurstTM.
nRF24E2 is also a subset of the nRF24E1 chip, which means that it contains all
functions of nRF24E1 except the radio receive functions, and it also means that it is
fully program compatible with nRF24E1.
