The SX1278-M1 is a 433Mhz wireless module using the Semtech SX1278 chip. The frequency is configured in software, and will typically be used for the 430 to 435MHz ISM band(contry dependant). The SX1278 is a revolutionary new chip enabling wireless communications at distances up to 15km, using Semtech's LoRa(Long Range) technology. This chip also supports high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g.
This module can be assembled with the SX1278 chip. The chip is identical when used for 433MHz operation. This module is based on the Semtech SX1276RF1JAS reference designs.
