    TS100 is no longer recommended by Ralim, see Github Ralim's IronOS. see Readme here a lot of new TS100 and TS80 now have issues loading IronOS and people are stuck with miniware firmware. I would avoid.

    V2, must unplug if you want to swap short & long tips as IronOS auto-reads resistance on boot-up. If you try to hot swap, or you will have strange behavior. In the future, Ralim might come up with another method, but that is the current way V2 works.This is general information, if you need more details or how the menu/settings work, read Documentation folder in Github Ralim/IronOS. Some hardware details/schematics on Pine64 Pinecil Wiki.

    The Pinecil is Pine64’s most polished product, and I congratulate them for getting such a high-quality soldering iron down to such a low price point ($26).

    Even if the Pinecil weren't open hardware running on open firmware, it would still be an incredible value. But it is, and I can't find a single thing to criticize about it.

    Of course you don't need an OS, but an OS is nice.

    An OS is nice because you can have multiple real-time tasks with different priority levels, so that you can, for example, update the screen without worrying that it will screw up the PID control loop maintaining the iron's temperature.

    The screen is nice because you can see what temperature the iron is set to and what temperature it's measuring. This makes it easier to set the temperature. Also IronOS lets you set the cutoff voltage so you don't kill your batteries by draining them down to zero, and it has an option to correct inaccurate temperature readings from the tip by calibrating the tip.

    PID temperature control is nice, not only because the iron is ready for use much more quickly and weighs less, but also because it allows you to solder things to big copper pours without overheating your iron all the time, which means you burn components and lift traces a lot less often.

    A 32-bit processor is nice because it means you can address the entire 128 KiB of Flash without shitty memory segmentation headaches when you're writing the firmware. Also you can use 32-bit math for everything instead of constantly worrying about overflow.

    The GD32VF103 used in the Pinecil doesn't have memory protection, so IronOS might not be the kind of operating system you're thinking it is. It doesn't have, for example, a filesystem, a command prompt, a GUI, a task list UI, or a networking stack.

    But if you really need to, you can solder your circuits by heating up a chunk of brass in the flame of your gas stove, then pressing it to the circuit board before it cools off. I've done it. But I'd rather not.

    Lower the temperature or turn off when not moved for some time, better temperature control via PIDs, set a voltage cutoff when running off battery packs...
