Overview This module uses the 2.4GHz transceiver from Nordic Semiconductor, the nRF24L01+. This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature - very nice! Note: We now populate these boards with the nRF24L01+. The '+' version of the IC has improved range, sensitivity, and data rates. The command set is backward compatible with the original nRF24L01. Features Voltage: 3-3.6V (recommended 3.3V) V Maximum output power: +20dBm Emission mode current(peak): 115mA Receive Mode Current(peak): 45mA Power-down mode current: 4.2uA Documents Please visit our wiki page for more info about this product.
