Product ID


LoRa™ is one of the main technologies for building a low-power WAN (LPWAN). It has the advantage of low power consumption, long distance, and the use of unlicensed ISM bands (Industrial Scientific Medical). LoRa™ technology is developed and licensed by Semtech, USA. With the patented LoRa™ modulation technique the receiving can be up to -148dBm. Therefore, a far distance can be achieved even when using low power transmission.

The BCM-1278-C18 is a LoRa™ module based on the Semtech SX1278 chip. It supports the frequency range of 405MHz – 525MHz. It integrates SX1278 transceiver IC and high frequency matching circuit. To use this module, you only need to connect an antenna and use digital controlling method.

This module is 16-pin stamp hole package type (2 x 8-pin, 2mm pitch). If you don’t have a PCB to connect this module, we recommend that you use the breakout board BCT-1278-C18 which has pulled out the pins and added an antenna for ease of use. In addition, two LoRa™ modules are required to communicate with each other.
