Description:

500mW 433MHz Lora data radio modem with TTL/RS232/RS485 interface Module DRF1278DX is a type of 500mW long range low data rate 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 DRF1278DX modules easy to realize the robust and reliable wireless link.

The DRF1278DX module is similar to the DRF1278DL module in function and also have three working modes: Standard Mode, Low Power Mode and Sleep Mode. Comparing to DRF1278DM, it doesn't contain star networking mode and only acts as a transparent data radio modem. According to the interface, it can be divided into DRF1278DX1 (TTL interface), DRF1278DX2 (RS232 interface) and DRF1278DX3 (RS485 interface).
