## What it is
IronOS is open-source replacement firmware for portable soldering irons such as the Miniware TS100/TS80/TS101, Pinecil, and Sequre models. It provides full smart-iron features including temperature control, PD/QC power negotiation, battery cutoff protection, and a multilingual on-device settings menu.

## Use cases
- replace stock firmware on a TS100 soldering iron
- flash custom firmware onto a Pinecil
- add USB PD and QC power negotiation to a portable soldering iron
- set battery cutoff voltage to protect lithium cells while soldering
- change soldering iron interface language
- customize boot logo on a mini soldering iron

## When to choose
- you own a supported Miniware, Pinecil, or Sequre soldering iron and want better temperature control and settings
- you need PD/QC/EPR power negotiation or battery protection on a portable iron
- you want a multilingual, actively maintained open-source firmware

## When to avoid
- your iron model is not on the supported hardware list
- you need to change settings over USB while the firmware is running
- you have a TS100 with a cloned STM32 chip that flashes unreliably
