DRF1276DM is a type of long range low data rate data radio modem based on SX1276 from Semtech. DRF1276DM is a low-cost sub-1 GHz transceiver module designed for operations in the unlicensed ISM (Industrial Scientific Medical) and LPRD bands. Frequency spectrum modulation/demodulation, multi-channel operation, high bandwidth efficiency and anti-blocking performance make DRF1276DM modules easy to realize the robust and reliable wireless link.
The module can work in two different modes: Standard mode and Star network mode. In the standard mode DRF1276DM acts as transparent data radio modem which it communicates with the host at the preset data format without encoding / decoding needed. In start network mode, one module will be the configured to the central node and other modules are set to node modules. The communication between the central module and node module are bidirectional but the node modules can not talk with each other. Please note that the module doesn't contain lorawan protocol. Therefore the star network feature of this module is used with itself protocol so it is not compatible with lorawan.
Applications:
Wireless Gas/electric meter, wireless sensor network, Automatic data logger, Industrial telemetry, Home automation, Remote keyless entry, Robotics control.
Please note:
This package includes 2pcs DRF1276DM and 2pcs antenna. The DRF1276DM has wide working frequency range so it can be used in 868Mhz or 915MHz. However the bandwidth of antenna is limited. Therefore we offer 915Mhz antenna for customers from south America,north America, Australia and New Zealand by default. For other territories including Africa, Asia, Europe, etc, we will offer 868Mhz antenna by default. If customers need different antenna frequency, please leave this message in order page in case we ship the wrong antenna.
