IronOS is a powerful soldering iron control firmware that was originally developed for the TS100 but now supports various other devices. The firmware includes standard features of a ‘smart’ soldering iron along with additional tweaks and extras. It is available in 31 different languages and supports both power options for soldering irons, whether they are powered by a ‘smart’ source or batteries. The firmware does not support changing settings through the USB port, and logos are edited and flashed like firmware. The content also provides information about recommended purchases and features unique to certain devices. The firmware is feature complete for use as a soldering iron and welcomes suggestions for improvement. IronOS supports a menu system for easy access to settings and various operations. Translations for missing languages can be contributed, and the code is licensed under GNU GPLv3. The firmware does not provide commercial support but can be distributed with links to the original page.+
