SAMD21 Pro RF - LoRa
The SparkFun Pro RF is a LoRa-enabled wireless board that marries a SAMD21 and a long-range RFM95W to make a compact and easy-to-use IoT Arduino board. With its fast MCU and excellent point to point data transmission in the 868/915MHz ISM band with LoRa capabilities, the Pro RF is a great choice for anyone interested or experienced in utilizing long range data communication.
The Pro RF also includes a power switch and 2-pin JST connector for powering from a battery. By closing a few jumpers on the underside of the SAMD21 Pro RF initiates LoRaWAN mode on the radio module making it a node in a distributed sensor network.
The RFM95 can be set to use 915 (US) or 868 (EU) in the Arduino code.
To use the 868 MHz radio on the gateway you will need an antenna - for which you have two choices. You may cut a length of solid-core wire to 86 mm for a through-hole antenna connection with strain relief or you can use a 868MHz antenna with a U.FL connector for higher performance.
