Conexio Stratus: a tiny, powerful, versatile cellular IoT prototyping platform (schematics, firmware, manuals, etc.)

The Conexio Stratus is a small (50.8mm x 22.86mm) yet powerful development kit for creating cellular connected electronics projects. It runs the best-in-class Zephyr RTOS for connected devices and is a battery-powered platform ideal for prototyping cellular IoT systems such as asset tracking applications, environmental monitoring, smart meter monitoring, and more. Equipped with Nordic nRF9160 System-in-Package (SiP), it supports LTE-M, NB-IoT and Global Positioning System (GPS). Stratus has two external U.FL antennas onboard, one for GPS and one for LTE-M/NB-IoT, enabling it to support LTE bands worldwide.
