ST87MXX shield

Overview

The EVKITST87M01 is an evaluation board for the ST87M01 NB-IoT module. It is designed as an X-NUCLEO Shield form factor with an Arduino compatible connector. Besides, two HOST connections to ST87M01 are possible: a PC or associate board.

The ST87M01 is a high-performance, fully programmable, ultra-compact, and low-power LTE Cat NB2 NB-IoT industrial module series, offering comprehensive worldwide band coverage and advanced security features.

Requirements

This shield can only be used with a board that provides a configuration for Arduino connectors and defines node aliases for UART and GPIO interfaces.

An NBIOT SIM, NanoSIM format, should be plugged in the SIM card holder to enable modem network connection.

Build and Programming

To compile, set --shield st87mxx when you invoke west build.

Then compile a sample, e.g.,

west build -b your_board --shield st87mxx samples/net/sockets/http_client
west flash
