The ST87M01 cellular data-communications module integrates NB-IoT certification and an optional ST4SIM embedded SIM. The module features dual communication capabilities through NB-IoT cellular connectivity and wireless Meter-Bus (wM-Bus), providing redundant data transmission channels for applications like utility consumption monitoring.
A software-defined radio enables dynamic switching between NB-IoT and sub-GHz wM-Bus modes. The module supports direct code embedding for basic applications and connects to host microcontrollers for more complex implementations. The variant with an integrated multi-constellation GNSS receiver operates during NB-IoT sleep cycles for power efficiency.
Measuring 10.6mm x 12.8mm, the industrial-grade qualified module serves multiple applications including industrial monitoring, factory automation, smart agriculture, environmental sensing, and infrastructure management. The module comes pre-loaded with a Vodafone profile for cellular connectivity.
The ST87M01 platform handles utility metering, asset tracking, and remote worker monitoring. All components are designed and manufactured by ST, supporting supply chain management and product longevity.
