Home > Product > Data Radio Modems > Medium Power Module
DRF1278DL1 is a type of long range RS232 interface data radio modem based on SX1278 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 DRF1278DL1 modules easy to realize the robust and reliable wireless link.

DRF1278DL1 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. DRF1278DL1 only has RS232 interface but DRF1278DL2 has RS485 interface . Comparing to DRF1278DM module, DRF1278DL1 doesn’t have star networking function. Users can set both DRF1278DM and DRF1278DL1 modules to standard mode to make them compatible.
