SparkFun LoRa Thing Plus – expLoRaBLE

The SparkFun expLoRaBLE Thing Plus is a Feather-footprint development board with the NM180100 system in package (SiP), from Northern Mechatronics. Thanks to the NM180100, as well as the Ambiq Apollo3 microcontroller and the Semtech SX1262 LoRa transceiver, this Thing Plus is a highly integrated LoRa® module supporting both 868MHz and 915MHz bands and Bluetooth® Low Energy. On top of all else, the expLoRaBLE Thing Plus utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system!

The NM180100 SiP includes a Semtech SX1262 LoRa module paired with the Apollo3 MCU, which is used in the SparkFun Artemis Module. This provides the board with compatibility in the Arduino IDE, through our Apollo3 Arduino core. With both the BLE and LoRa capabilities of the expLoRaBLE you will be able to operate as a Bluetooth enabled LoRa node.

You won’t have to worry about how to hook up an appropriate antenna, either. The SparkFun expLoRaBLE Thing Plus has been equipped with a simple U.FL connector. With the U.FL you will have your choice of BLE and RF antennas to choose from.
