The X-NUCLEO-SAFEA1 expansion board is based on the STSAFE-A110 secure element. It can be used with any STM32 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-SAFEA1 expansion board is used with free X-CUBE-SAFEA1 or X-CUBE-SBSFU software packages containing sample code to demonstrate how to implement security applications. https://elecena.pl/product/16970577/x-nucleo-safea1a-secure-element-expansion-board-based-on-stsafe-a110 2020-06-14 https://elecena.pl/product/16970577/x-nucleo-safea1a-secure-element-expansion-board-based-on-stsafe-a110 2021-04-02 https://elecena.pl/product/16970577/x-nucleo-safea1a-secure-element-expansion-board-based-on-stsafe-a110 2021-05-20 https://elecena.pl/product/16970577/x-nucleo-safea1a-secure-element-expansion-board-based-on-stsafe-a110 2021-07-24 https://elecena.pl/product/16970577/x-nucleo-safea1a-secure-element-expansion-board-based-on-stsafe-a110 2022-06-12 https://elecena.pl/product/16970577/x-nucleo-safea1a-secure-element-expansion-board-based-on-stsafe-a110 2022-06-24 https://elecena.pl/product/16970577/x-nucleo-safea1a-secure-element-expansion-board-based-on-stsafe-a110 2023-03-26 https://elecena.pl/product/16970577/x-nucleo-safea1a-secure-element-expansion-board-based-on-stsafe-a110 2023-07-18 https://elecena.pl/product/16970577/x-nucleo-safea1a-secure-element-expansion-board-based-on-stsafe-a110 2025-06-27 https://elecena.pl/product/16970577/x-nucleo-safea1a-secure-element-expansion-board-based-on-stsafe-a110 2026-03-11
