Seamless Worldwide IoT: Conexio Debuts Stratus Pro with Global Cellular Compatibility

Conexio Technologies has unveiled the Conexio Stratus Pro, an advanced cellular-based microcontroller board designed for IoT applications. This new product, available soon on Crowd Supply, features the Nordic Semiconductor nRF9161 SiP and nPM1300 PMIC in a Feather form factor, enhancing its versatility and performance for diverse projects.

The Stratus Pro integrates a Nordic Semiconductor nRF9161 system-in-package (SiP) that includes a microcontroller, LTE cellular radio, and GPS receiver. Additionally, the board houses a Nordic nPM1300 power management IC (PMIC) and a TI BQ25185 IC for charging various battery chemistries such as Li-ion, Li-Poly, and LiFePO4. An STMicroelectronics three-axis accelerometer further extends its functionality. The nRF9161 features an Arm Cortex-M33 with 1MB of flash memory and 256KB of RAM, supported by an external 16-kilobit EEPROM. The cellular modem is compatible with LTE-M and NB-IoT and is DECT NR+ ready, ensuring robust global connectivity.

Adopting the Adafruit Feather form factor, the Stratus Pro’s PCB measures 66.04 x 25.40 millimeters, offering 28 GPIO pins, a programmable push button, and an LED. It includes a SparkFun Qwiic-compatible connector for easy peripheral connections without soldering and can be programmed via USB-C or the onboard SWD/JTAG connector. Designed for seamless global use, the device supports eSIM and software SIM, providing reliable connectivity in over 100 countries. It comes with a data plan offering 500MB of cellular data and 250 SMS messages, valid for 10 years.

Conexio plans to open-source the Stratus Pro hardware design post-Crowd Supply campaign. Software examples and board design files will be available on Conexio’s GitHub, with projects built using the Nordic nRF Connect SDK on the Zephyr RTOS. Comprehensive documentation is available now, inviting users to explore the full potential of the Stratus Pro.
