Product overview


The X-CUBE-IOTA1 expansion software package for STM32Cube runs on the STM32 and includes middleware to enable the IOTA Distributed Ledger Technology (DLT) functions.

The IOTA DLT is a transaction settlement and data transfer layer for the Internet of Things (IoT). IOTA allows people and machines to transfer money and/or data without any transaction fees in a trustless, permissionless and decentralized environment. This technology even makes micro-payments possible without the need of a trusted intermediary of any kind.

The expansion is built on STM32Cube software technology to ease portability across different STM32microcontrollers.

The current version of the software runs on the B-U585I-IOT02A discovery kit for IoT node and connects to the Internet through the attached WiFi® interface.

The software is also available on GitHub, where the users can signal bugs and propose new ideas through Issues and Pull requests tabs.
