(1) Operating voltage: 1.8V~3.6V, 3.3V recommended(2) Work in 433MHz band license-free use(3) High operating rate 500kbps, support 2-FSK, GFSK and MSK modulation(4) Software modifiable baud rate parameters to better meet customer requirements under different conditions of useHigh baud rate: faster data transmission rate. Low baud rate: stronger anti-interference and penetration ability, longer transmission distanceHigh sensitivity (-110dBm at 1.2Kbps, 1% packet BER)Built-in hardware CRC error detection and point-to-multipoint communication address controlLow current consumption (15.6mA in RX, 2.4Kbps, 433MHz)Programmable control of output power up to +10dBm for all supported frequenciesWireless wake-up function, support low-power electromagnetic wave activation, wirelessly wake up the low-power sleep state of the devicesupport for automatic channel clearance access (CCA) before transmission, that is, the carrier listening systemfast frequency change synthesizer to bring the appropriate frequency hopping systemModule can be software set address, software programming is very convenientStandard DIP pitch interface for embedded applicationsSeparate 64-byte RX and TX data FIFOActual transmission distance of 200 meters or more in open area (depending on specific environment and communication baud rate, etc.)Material: PCBColor as shownPackage Contents:2 x moduleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
