Product Overview
nRF905 Norway Nordic introduced a single-chip RF transmitter chip, 32-pin 5mm x 5mm QFN package, work in 433,868,915 MHz ISM (Industrial, Scientific and Medical) channels, including the 433 band free of charge. nRF905 by the frequency synthesizer, the receiver demodulator, a power amplifier, a crystal oscillator, modulator and other functions, the need for external SAW filter can also have a good communication effect. nRF905 SPI interface can communicate with any MCU, address output power, and communication channels through configures a program so it can be used for multi-machine communication. the The nRF905 integration TM technology of ShockBurst, can automatically process the packet prefix, and built-in CRC checksum function, to ensure reliable data transmission. nRF905 low power consumption, the launch of the power of-10dBm, operating current is only 11mA; while the corresponding receiver operating current of only 12.5 mA chip software can set the idle mode, shutdown mode, easy energy-saving design. Suitable for industrial data acquisition, wireless alarm and security systems and other areas.
Basic Features
(1) 433MHz license-free ISM bands use;
(2) Communication rate 50kbps operating frequency range 422.4-473.5MHZ
(3) efficient GFSK modulation, anti-interference ability, especially for industrial control applications;
(4) The operating frequency can be software set to meet the multi-point communication and frequency hopping communication needs;
(5) The built-in hardware 8, 16-bit CRC error detection and point-to-multipoint communication address control;
(6) op amp operating voltage 4.5-5V programming voltage 1.9 - 3.6V;
(7) transceiver mode switching time 1ms
(8) SPI programming interface, software set the address, address up to 2 ^ 32
(9) integrated address match, Carrier Sense, send and receive completion status indicator
(10) module peak current <30mA, communication distance of 100 meters or more;
(11) Standard 2.54mm DIP spacing interfaces for embedded applications
The same time, in order to facilitate the users to develop, we provide supporting evaluation kit escort for product development, wireless application development greatly accelerated, and avoid unnecessary misunderstanding.
