IronOS is open source firmware for soldering irons and heating plates that replaces the default firmware on supported devices.
The firmware provides comprehensive control over soldering hardware by implementing standard smart soldering features with additional tweaks and settings. For devices powered by smart power sources like USB Power Delivery or Quick Charge, it offers negotiated power and voltage settings. For battery-powered devices, it includes battery cutoff voltage protection. All configuration happens through an onscreen menu rather than USB connectivity. The firmware supports custom logos that can be edited on a computer and flashed alongside the firmware binary. Multilingual support spans across numerous language options.
Developers and hobbyists maintaining or modifying soldering irons should consider this firmware if their device appears in the supported hardware list, which includes Miniware models, Pine64 Pinecil variants, and Sequre devices. The project suits anyone wanting enhanced control over their soldering equipment beyond manufacturer defaults. The firmware is considered feature complete for daily use, making it stable for production soldering work. Some newer high-resolution OLED displays on certain models have partial support with cropped views currently usable while full resolution support remains in progress.
The project maintains active engagement with feature requests and suggestions from users. Development shows consistent attention to hardware support expansion, with the codebase regularly updated to accommodate new soldering iron models and variants. The maintainer actively documents installation procedures and provides comprehensive guidance for users flashing the firmware to their devices.
