How to use STM32 Nucleo expansion board based on the STSAFE-A110 secure
Introduction
The
X-NUCLEO-SAFEA1B
expansion board is based on the
Nucleo
development board.
The on-board STSAFE-A110 is customized with a standard profile for evaluation and is compatible with the Arduino UNO R3
connector.
The
X-NUCLEO-SAFEA1B
expansion board is used with free
containing sample code to demonstrate how to implement security applications.
