Conexio Stratus And Stratus Pro IoT Development Boards

Conexio’s Stratus and Stratus Pro boards are a plug-and-play, compact solution (50.8 mm x 22.86 mm) for quickly developing or adding to IoT products that require GNSS and cellular connectivity for a global marketplace. These featured-packed boards can be used to reduce costs and effort during the R&D process, or they can be directly embedded into end products for faster time to market in applications such as:

  • Asset tracking
  • Industrial
  • Smart metering
  • Energy infrastructure
  • Point-of-Sale
  • Supply-chain management
  • Healthcare
  • Wearables
  • Smart agriculture

The Stratus board is based on Nordic’s nRF9160 SiP, which offers an Arm Cortex-M33 application processor supported by 1 MB of flash and 256 kB RAM, as well as a multimode modem that supports GNSS, LTE-M, NB-IoT, and Cat-1 connectivity, offering connectivity to the cloud or acting as a gateway for other devices. The Stratus Pro will be released in Q1 2024 with Nordic’s new nRF9161 SiP that will provide access to private 5G mesh networking capabilities (DECT NR+ ready, full specifications pending). Two connectors for external u.fl antennas are provided to support the GNSS (active) and cellular connectivity.

As well as out-of-the-box cellular connectivity with 500 MB of data valid for 10 years with speed up to 1 Mbit/s (via a nano SIM, no lock-in or hidden fees), the Stratus board features sensors for temperature, humidity, and pressure, plus a 3-axis accelerometer, all very useful for asset monitoring while in transit. These can be added to via the 26 mixed-signal GPIOs (26 digital, 6 analogue) with SPI, I2C, and UART interfaces. A user-programmable LED and 2 buttons are included for initial testing, and the board can be programmed via USB type-C connector, with an onboard JTAG/SWD connector for debugging.

Stratus also features a connector for a LiPo battery, supported by the onboard battery charging-and-monitoring system, an e-peas AEM10941 energy harvester PMIC for running the board autonomously on solar energy, and – perhaps most disruptive of all the features – an ON/OFF power switch for fully powering the device off during product shipping or long-term storage, without having to remove the battery.

A carrier board is included with the development kit, which provides easy connectivity to popular third-party boards and solar energy harvesters.

To support the smooth running of your IoT application, Stratus runs Zephyr RTOS and supports additional services/functions/platforms such as OpenCPU, Over-The-Air updates, Edge Impulse, Memfault, and Golioth. Datacake can be used for easy data visualization and dashboard creation without the need for programming. While Stratus supports networks using 4G/LTE/Cat-M1/NB-IoT with 200+ carriers in over 180 countries – with automatic carrier switching for the best service possible – Stratus Pro aims at 95% Global coverage using 400+ networks.
