CC1101/433 / wireless transceiver modules / NRF24L01/905
Features:
( 1 ) Operating voltage : 1.8V ~ 3.6V, recommend close to 3.6V, but not more than 3.6V ( preferred 3.3V)
(2) 315,433,868,915 MHh the ISM and SRD band
( 3) The maximum rate of 500Kbps, supports 2-FSK, GFSK and MSK modulation
( 4 ) can change the baud rate parameter software to better meet customer requirements in different conditions
High baud rate : faster data transfer rates
Low Baud rate: transmission distance and stronger anti-interference ability to penetrate farther
( 5 ) high sensitivity (1.2kbps under -110dBm, 1% packet error rate )
( 6 ) built-in hardware CRC error detection and control multipoint communication address
( 7 ) a lower current consumption (RX in , 15.6mA, 2.4kbps, 433MHz)
( 8 ) programmable control of output power, support for all frequencies up to +10 dBm
( 9 ) wireless wake-up function , supports low-power electromagnetic activation , wireless wake- low-power sleep state devices
( 10 ) Support automatic cleanup before transmission channel access (CCA), namely Carrier Sense System
Appropriate frequency hopping systems ( 11 ) fast frequency synthesizers brings changes
( 12 ) modules can be software set address , software programming is very convenient
( 13 ) Standard DIP spacing interfaces for embedded applications
( 14 ) separate 64-byte RX and TX data FIFO
( 15 ) Transmission distance : open 300 to 500 meters transmission ( depending on the specific environment and communication baud rate setting may be the case , etc. )
