NRF905 Wireless Transceiver Module Transmitter Receiver Board NF905SE With Antenna FSK GMSK Low Power 433 868 915 MHz | Электронные

Application areas:   Wireless monitoring, remote monitoring, telemetry, small wireless networks, wireless meter reading, access control systems, cell paging, industrial data acquisition systems, wireless tags, identification, contactless RF smart cards, small wireless data terminals, fire safety systems, wireless remote control systems, Biological signal acquisition, hydro-meteorological monitoring, robot control, wireless 232 data communications, wireless 485/422 data communications, digital audio, digital image transmission.   Features:   The triple-band transceiver sends and receives one at a time. The operating frequency is 433/868 / 915MHz GMSK modulation, which is widely used in the international ISM band. It has strong anti-interference ability and is especially suitable for industrial applications. It uses DSS + PLL frequency synthesizer technology with excellent frequency stability and high sensitivity. 100dBm low operating voltage (2.7V), low power consumption, standby only 1uA, to meet the requirements of low-power devices Maximum transmit power of +10 dBm With multiple channels (up to 170 or more), especially to meet the needs of multi-channel work Special occasions, working speed up to 76.8Kbps Peripheral components at least (only 10), the basic without debugging. Due to the low transmitting power and high receiving sensitivity, there is no need to apply for a license, and the open area can be used up to 1000 meters        Electrical Characteristics:   nRF905 working frequency band: 433/868 / 915MHz   Number of channels: 170   Function: Transmit / Receive   Frequency stabilization method: PLL   Modulation method: FSK / GMSK   Maximum output power: + 10dBm   Sensitivity: -100dBm   Maximum working rate: 76.8Kbit / s   Working voltage: 2.7--3.3V
