(1) working voltage: 1.8V~3.6V, recommend close to 3.3V, but not more than 3.6V
(2) 315, 433, 868, 915Mh ISM and SRD bands
(3) the highest rate of 500kbps, 2-FSK, GFSK and MSK modulation
(4) and high sensitivity (1.2kbps -110dDm, 1% data packet error rate)
(5) built-in hardware CRC error detection and point to multipoint communication address control
(6) lower current consumption (RX, 15.6mA, 2.4kbps, 433MHz)
(7) power output programming control, for all support the frequency can reach +20dBm
(8) wireless wake-up function, support for low power electromagnetic wave activation function, wireless wake-up device low-power sleep state
(9) to support the transmission of automatic cleaning channel access (CCA), carrier sense system
(10) the fast frequency changes the appropriate frequency synthesizer has jump system
(11) module software address, software programming is very convenient
(12) 64 bytes of RX and TX data FIFO alone
(13) the transmission distance: open transmission 2500 meters (depending on the specific environment and the communication baud rate setting situation may be)
