The RA-01 is a 433Mhz wireless module using the Semtech SX1278 chip, with a pad for soldering an antenna. The frequency is configured in software, and can be configured for 410 to 525MHz. The SX1278 is a revolutionary 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 long range wireless capability is packed into a small (17 x 16mm) package and delivered without an antenna. This module enables 3.3V devices (like a Microcontroller for example) to communicate with remote nodes via a wireless protocol.
