nRF9160 DK

The nRF9160 DK is an affordable, pre-certifed single-board development kit for evaluation and development on the nRF9160 SiP for LTE-M, NB-IoT and GPS. It also includes an nRF52840 board controller that for example can be used to build a Bluetooth Low Energy gateway.

It has a dedicated LTE-M and NB-IoT antenna that supports a wide range of bands, to operate globally. LTE bands B1, B2, B3, B4, B5, B8, B12, B13, B14, B17, B18, B19, B20, B25, B26, B28 and B66 have been certified so far. See this for more details.
