The Stratus series is our flagship IoT Development Board for cellular-connected products. It is a battery-operated platform making it ideal for prototyping cellular IoT systems, for instance, asset tracking applications, environmental monitoring, and smart meter monitoring to name a few.&#x20;

Equipped with the Nordic Semi's nRF9151 & nRF9161 (Gen 2 devices) and nRF9160 (Gen 1 device) System in Package (SiP), it supports LTE-M, NB-IoT, and Global Positioning System (GPS). Stratus has two onboard external U.FL antennas, one for the GPS and the other for LTE-M/NB-IoT enabling it to support a global range of LTE bands.

Stratus has built-in battery charging, monitoring, and energy-harvesting circuitry which makes it easier to connect and recharge a Li-Po battery without having to replace the battery, creating fully energy-autonomous applications. In addition, Stratus incorporates an accelerometer and a temperature and humidity sensor for detecting movements and sensing the surrounding environment, right out of the box. Finally, Stratus provides 26 mixed-signal GPIOs for interfacing with external sensors, actuators, and other electronics.

To connect to the IoT cellular networks, Stratus comes preloaded with 500 MB of data and a total of 250 SMS valid for 10 years with service in more than 100 countries worldwide without additional costs, making it the most versatile IoT development kit in the market.

Stratus is great for connecting existing projects to the Cloud or as a gateway to connect other local endpoints without having to worry about the infrastructure cost.
