NRF905

Product Description:
NRF905 wireless transceiver module (on-board antenna) / PTR8000, optimal design in Nordic VLSI nRF905 latest revision package, based on smaller, more distant, while interference is strong, stable communication, particularly suitable for industrial control field, is One of the most mainstream wireless RF transceiver solutions
 
Basic characteristics:
(1) 433MHz license-free ISM band using open
(2) transmission and reception functions in one, send and receive complete interrupt flag
(3) 170 channels, can meet the multi-point communications and frequency hopping communications needs, achieve network communication, TDMA-CDMA-FDMA
(4) Built-in hardware 8/16 bit CRC, the development of more simple, reliable and stable data transmission
(5) working voltage 1.9-3.6V, low power consumption, standby mode only 2.5uA
(6) receiver sensitivity up to -100dBm
(7 ) transceiver mode switching time <650us
(8) for each transmit and receive up to 32 bytes, and the software is set to send / receive buffer size 2/4/8/16/32 bytes
(9) The module can be software set address, only when it receives the machine address will output data (provide interrupt instructions), can be directly connected to a variety of MCU, software programming is very convenient
(10) 10 mW maximum transmit power, transmit mode : maximum current <30mA; receive mode: Current 12.2mA
(11) Built-in SPI interface, can also be achieved through I / O port simulation SPI. SPI clock up to a maximum 10M
(12) standard DIP spacing interfaces for embedded applications
(13) emission rate of 5 0 Kbps, built-in PCB antenna onboard, open to communication distance up to 100 meters
(14) Module size: length 43 mm, width of 38mm (widest point), 21mm (narrowest point)
