    I would assume this is the Pinecil v2, as I don't think Sparkfun would be buying illegal clones to resell. If it is the v2 the fact that the boot logo can be customized and the community mods should be mentioned. Possible mods include a thumbscrew instead of the phillips screw for securing the tip, addition of a hall effect sensor to auto wake/sleep the unit when put in a stand/case, clear enclosure and internal RGB LED (seperate items), and an LED ring created by @RushanEE. Makes this much more than just another soldering iron (even if it is portable).

    But since I'm the first here I'll review the thing: it's freaking amazing. I've been hunting for a portable iron for years but couldn't find anything remotely usable let alone something to compete with the Hakko FX888D. I even tried Hakko's portable offering and was supremely disappointed. Granted the TS100 was a decent first step but the Pinecil v2 brings this wish fully to fruition. First of all, it's freaking less than $40. But it also heats up in 6 seconds flat, has hot-swappable tips, and can even run off a 4s quadcopter LiPo battery. I honestly haven't even used my Hakko since buying the Pinecil v2. The new MCU didn't support custom boot logos at first but does now, and the community has aggregated a decent selection of pre-made ones if you don't want to go about creating your own. I mean, what good is a programmable open-source thing with an LCD if it doesn't remind me to soil my pants when it's turned on?

    Goofy nonsense aside, This is an amazing soldering iron. It's that on its own but it's also portable, can be powered by DC 2.5mm jack or USB C (and all you need is an XT-60 to 2.5mm barrel pigtail to power it with a 4s LiPo), is open source, supports custom boot logos, and did I mention it can be controlled via Bluetooth? I don't know why I don't see that mentioned very often. The only negative I have about this product (and it's extremely minor by comparison) is that they never developed a JL-02 tip for the v2 (there are JL-02 TS100 tips that are compatible they're just longer than normal v2 tips) which is the only tip I use anymore. It's a fine conical tip that has a 30º bend near the end allowing one to hold the iron at a comfortable angle and still have the tip parallel with the board being worked on. This tip seems to be somewhat of a sleeper as not many people know about it; or at least I assume so because I can't imagine anyone trying it and not using it most of the time. The stock tip is very usable I'm just spoiled by my JL-02s. Also there are some amazing cases on the usual 3D printing CAD sites that snap closed into a tidy little package while still having room for the iron, an extra tip, a syringe of flux, a ball of brass sponge, a micro spool of solder, some wick, a USB C cable (specifically the red 1.5m one that Pine sells), and a stand utilizing a ball bearing to insulate from the heat. It's better than any manufactured case I've seen. Oh, and last but not least, Pine also makes a breakout board you can plug into the back of the iron inline with a power supply that breaks out the JTAG and other ports. Amazing.

    Honestly even if you're not in the market for a new iron I would pick this up. It's an insanely good deal with more mod support that you ever have seen. You won't be disappointed.
