2Mbit/s, 1Mbit/s, 250Kbit/s, three selectable transmission rate. MultiCeiver hardware and six receiver functions. 2 Mbit/s make high-quality VoIP is possible. +/- 60 ppm crystal. Only require an external inductor in the antenna matching There is no need multi-layer PCB. 5V tolerance level inputs. Improved ShockBurst and the serial interface can be easy to connect with a variety of low-cost MCU. There si no need SPI interface with the MCU. Received in the rate of 2Mbit/s, the peak current is 12.5mA. When the rate of 2Mbit/s @ 0dBm output,the peak current is 11mA. Power-down mode, power consumption is 400nA. Standby mode, power consumption is 32uA. 130us fast switching and wake time. With voltage regulator:Oltage regulators on board. Built-in 2.4GHz antenna,support up to six channels of data reception. Low operating voltage: 1.9-3.6V Small size:15*29mm
