This module uses the newest 2.4ghz transceiver from Nordic Semiconductor, the nrf24l01+. It integrates a complete 2.4ghz RF transceiver, RF synthesizer, and baseband logic including the Enhanced shockburst(tm) hardware protocol accelerator supporting a high-speed SPI interface for the application controller.
The ‘+’ version of the IC has improved range, sensitivity, and data rates. The command set is backward compatible with the original nrf24l01.
