    Just a heads up, looks like the wiring diagram here is not entirely correct. Specifically the female TRRS wiring, I ended up needing to do the following (using pin numbers on diagram)

    1. Red Servo (5v, RJ45 pin 3, white-green)
    2. Red Fan (12v, RJ45 pin 5, white-blue
    3. Orange Servo (signal, RJ45 pin 6, green)
    4. Black Fan/Brown Server (Gnd, RJ45 pin 4, blue)

    I verified the male wiring connection and everything lined up so maybe a difference in the part supplier for the female?

    Did you verify which cable type you have? I have a massive migraine, so tracking down what's wrong is not going to happen tonight. I've wired many MicroDampers following those instructions without fail though.

    Yeah, Type B cable for sure. I wired the male end exactly as described in the doc so it really seems like the pinout on the female for my parts doesn't line up.

    Not a big deal for me, just thought I'd post in case somebody else runs into it. Really satisfied with my purchase

    It looks like you wired it exactly I how I explain (well I'm inferring because you mention pin 5 and 6 etc which don't exist). Don't know what your issue was...

    For those having problems soldering the male TRRS connector wiring you may want to look into this.

    There's a reason rj45 jacks are used for most data + power applications!

    Yeah it's too bad a female RJ45 jack takes up about a 1/4 of the volume of a MicroDamper. The TRRS jack is a good solution, nice and easy to use too. There's a reason temperature probes use a very similar jack

    This is a great idea. Personally, I didn't have any trouble with the wiring itself. Its the insulation that is near impossible and has caused headaches. Attempting to solder around the shrink wrap on the male TRRS is a fools errand, if your attempting to wrap each pole individually. I'd love to see it done. I ended up cutting small strips of electrical tape. and wrapping each pole under a magnifying glass. Not easy. I found that if not doing this, every time the cord was touched or bent, it through a short and rebooted my HeaterMeter.

    I haven't had any problems with this. Are you using an appropriately sized soldering tip? You should use the same one that should be used to solder the HeaterMeter; one that comes to a sharp tip.

    I'll have to find a tripod and everything, I'm not setup for taking youtube videos - never made one before. I will get a video done eventually though!
