Dorji DRF1278DM Data Radio Modem
DRF1278DM, one of the Dorji products, is a powerful transciever modem module operating in the ISM band 430MHz frequency. The module uses Semtech SX1278 integrated, with its meshed structure for 50 Ohm antenna and 10ppm crystal, it has the ability to work both as a transparent modem in standard mode and in Star network structure. Data exchange is ideal for RS232 or RS485 because it serves to transfer whatever comes from the serial port. In Star Mode, one module is set as the center and the others are set as the node. Those that are set as node can communicate with the center but cannot communicate with each other. Transmitter power provides bidirectional communication around 1km-1.5km in an open area of 20dbm - 100mW. Since the communication protocol is transparent, it is also suitable for Aruino platforms.
