Check the listing for details. 868 915MHz Lora sx1276 RS485 wireless module DRF1276DL2--2pcs. Condition: New. Listed at 29.98 USD. DRF1276DL2 is a type of long range RS485 interface data radio modem based on SX1276 from Semtech. It 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 DRF1276DL2 modules easy to realize the robust and reliable wireless link. Features: * LoRaTM Frequency Spectrum * 868/915Mhz ISM frequency band * -138dBm receive sensitivity * 20dBm Max. output power * RS485 interface * Serial port wake-up * Wireless wake-up * Supply voltage 3.4~5.5V DRF1276DL2 is a transparent data radio modem which means the module transfers or receives data from the host with preset data format without encoding/decoding needed so the communication between them is transparent. Comparing to DRF1276DM module, DRF1276DL2 doesn’t have star networking function but it has power-saving ability. Notes: The package includes 2 pcs modules of DRF1276DL2 and 2pcs antenna. The DRF1276DL2 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.
