Conexio Stratus Pro is a tiny-yet-powerful development kit for creating cellular-connected electronic projects and products. Powered by the cutting-edge nRF9161 cellular modem from Nordic Semiconductor, Stratus Pro offers unparalleled versatility, reliability, and ease of use, making it the go-to solution for IoT developers worldwide. It is a battery-operated platform, making it ideal for prototyping cellular IoT systems, such as asset tracking, environmental monitoring, smart metering, and even industrial automation.
With LTE-M, NB-IoT, and GPS connectivity packed into a compact form factor, Stratus Pro ensures your devices stay connected in any environment. It enables real-time data transmission and location tracking with minimal power consumption. Future-proof your IoT projects with DECT NR+ readiness, ensuring compatibility with emerging cellular standards for enhanced performance and longevity.
Stratus Pro also supports platforms like Edge Impulse, Memfault, and Golioth, leveraging machine learning (ML) to provide seamless Over-the-Air (OTA) updates to your devices. ML capabilities are extremely helpful in implementing predictive maintenance in scenarios where uninterrupted operation is particularly important, such as in smart factories. For easy data visualization and dashboard creation, Stratus Pro also connects to Datacake, a low-code IoT platform that requires no programming.
Thanks to the nPM1300 PMIC and fuel gauge, you can remotely monitor your Stratus Pro’s battery vitals and charging status. Stratus Pro also has built-in charging circuitry that makes it easier to connect to and recharge the Li-Po battery, creating fully energy-autonomous applications.
In numerous battery-operated IoT applications, devices primarily spend most of its time in low-power mode. Hence, minimizing overall power consumption of Stratus Pro during this mode was a paramount design objective. We are thrilled with the outcome and have confirmed that Stratus Pro consumes less than 9 µA in its ultra-low power state.
Designed to be adaptable, Status Pro also embraces modularity. Its QWIIC connector and feather-compatible 28 header pins are ready to integrate with compatible modules, allowing you to extend its functionality with additional hardware like cameras, thermometers, or ultrasonic distance sensors.
In addition, the Conexio Stratus Pro is equipped with a USB Type-C port, enhancing its connectivity options. This port allows for easy connection with a wide range of devices and accessories, making charging, debugging, and programming a breeze.
Each Stratus Pro debvice comes pre-loaded with 500 MB of IoT data and 250 SMS messages, valid for 10 years, no strings attached.
Whether you’re deploying IoT solutions locally or internationally, Stratus Pro has you covered. With service availability in over 100 countries, you can confidently connect your devices anywhere, anytime. And if you want to migrate Stratus Pro to your local network of choice or provider, the switch is easy with eSIM and software SIM support.
To make the application and project development with Conexio Stratus Pro fun and fast for low-level application designers and novices alike, we made Stratus compatible with nRF Connect for Visual Studio Code. Using the nRF Connect plugin, you can build, compile, and deploy code to the Stratus Pro with minimal effort. Create projects with nRF Connect SDK and Zephyr RTOS with built-in templates created by the Conexio team.

Stratus Pro hardware was refined gradually over multiple pre-production revisions. These revisions were thoroughly validated and used by a number of pre-production testers and open-source contributors before becoming available to consumers. We have developed working relationships with several contract manufacturers in China, and we trust them to manufacture and assemble Stratus Pro electronics. We work closely with a number of distributors and vendors—including Nordic Semiconductor, who designed the main nRF9161 SiP module and nPM1300 PMIC, and Symmetry Electronics, to accelerate component acquisition to manufacture Conexio Stratus Pro consistently and with the highest level of quality.
