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 ShockBurst™. 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.
