Arduino Portenta CAT.M1/NB IoT GNSS Shield - ASX00027
📌 What It Is
The Portenta CAT.M1/NB IoT GNSS Shield (ASX00027) is an Arduino expansion board (shield) that adds cellular IoT connectivity (Cat.M1/NB-IoT) and global positioning (GNSS) to compatible Arduino boards, especially the Portenta lineup.
Built around the Thales Cinterion TX62 wireless module – low-power, highly efficient IoT connectivity.
Works with Arduino Portenta boards and also MKR form-factor boards.
Ideal for remote & wide-area tracking, monitoring systems, smart city endpoints, agriculture IoT, and industrial applications.

🧭 This shield turns an Arduino into a connected global tracker that can:
✔ Measure location (GNSS) worldwide;
✔ Connect sensors/data to the cloud via cellular IoT networks;
✔ Run secure internet services using embedded IP stack;
✔ Fit in low-power remote deployments.
📌 How It Works
🚀 Cellular IoT Connectivity
Supports both LTE Cat.M1 and NB-IoT — ideal for low-bandwidth, long-range IoT applications like sensor telemetry.
Can send data securely using MQTT, HTTP, FTP, etc.
Option to use eSIM for flexible carrier provisioning.
Use Cases:
✔ Fleet & asset tracking
✔ Environmental & agricultural sensors
✔ Utilities monitoring (water/gas meters)
✔ Smart city applications (parking, lighting, signage)
🛰️ GNSS Positioning
Integrated support for multiple GNSS constellations:
GPS, GLONASS, Galileo, BeiDou — gives better accuracy & reliability worldwide.
Use GNSS data (lat/lon/time/satellites) in your Arduino sketches for real-time location or geofencing.
⚙️ Software & Programming
Compatible with the Arduino IDE or Arduino Pro tools.
Libraries for handling cellular connectivity and GNSS parsing (e.g., NMEA sentences) are available.
Plug-in, power up, and begin coding — no separate power supply needed (powered from the Portenta host).
📦 Typical Projects
✅ Remote sensor node reporting data to cloud
✅ GPS tracker sending periodic location updates
✅ MQTT sensor network over NB-IoT
✅ Smart agriculture telemetry
✅ Industrial equipment monitoring
📌 Notes & Tips
📍 Some users report that under certain carrier restrictions LTE Cat.M1 connections may fallback to NB-IoT — ensure your network supports Cat.M1 if needed.
📍 Always check compatibility with your local cellular carriers and supported bands.
