SparkFun Thing Plus – nRF9160

SparkFun has teamed up with CircuitDojo to bring you the SparkFun nRF9160 Thing Plus, featuring the powerful Nordic nRF9160 microcontroller in a Feather-compatible footprint. This little chip is capable of both CAT M1 LTE and NB-IoT cellular communication and is designed to work with Zephyr, the go-to RTOS for embedded development. To make the Thing Plus even easier to use, this board utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system!

Not only can you take advantage of Nordic’s advanced power states, but you can also put the device into a low power standby state. Laboratory measurements are putting that mode at about 2µA of current. 2µA! It also features a 3.3V Buck-Boost which helps get every mWh from your batteries as possible.

No batteries? No problem! Power your nRF9160 Thing Plus externally with a USB-C cable. Keep it on at all times for high availability scenarios.

Want to persist data? The nRF9160 Thing Plus has a 4MB external flash for storing data while offline. Using external flash with a filesystem like LitteFS and you’ll have a project to recon with!
