    Looks good to me, TwinDad.

    I did check the datasheet and apparently there are no issues however you set the inputs. They even need to be the same for turning off the outputs. I don't like the...

    Well, the first thing to notice with modern ESU decoders: Get the latest JMRI (production) version. A lot has been done on ESU decoder support between 4.18 and 4.20 and quite another bit between...

    I don't know that chip, but I'd assume that too :) as well as some reasonable behaviour if both inputs are active for some reason (floating FET gate).

    I understand you are OK with always having...

    Yeah well, you got past the frog, so it doesn't really matter where exactly the rails join :)

    Well, not directly. It's a full-blown DCC command station for ops with Loconet support, 120 locos and an integrated LocoBuffer-clone for connecting a PC. Although the output power is heavily limited...

    Those two get my vote. Not sure whether I prefer the round or the parallelogram, definitely voting for the wider (higher) green background stripe to the lettering. Though maybe somewhere in between...

    Just a quick warning: UK customs are crazily busy with Brexit right now. Sounds crazy, since the rules for shipping to the EU are basically the same as for shipping to (for example) Canada, but all...

    That was going to be my first sentence on this :)

    There's one big problem in any H-Bridge: If you take a half-bridge (N-FET+P-FET with connected gates and drains, like your Q2/Q4) connected to...

    I can't really make it out from the picture: Did it lift because it got longer (or the wood shrunk)? Your note on having to unsolder it sound like that to me.

    In that case, you can "just" make a...

    Depends on what the stuff connects to. As a rule of thumb:

    Stuff that only connects to the track signal (like autoreversers) are compatible with each other (within the scope NDave and TwinDad...

    If you can, get it out. Try pushing with a toothpick from the outside, it may be press fit and not glued.

    If not, use liquid masking material. I've had good results with Micro Mask Liquid Masking...

    Depends on how large your layout is... The closer you get your boosters and "power managers" to your power districts the better.

    On an HCD or 8 x 4 that doesn't matter. But on an around-the-room,...

    Keep in mind the issue is not really how much current your locos draw but how much current your command station/booster(s)/circuit breaker(s) need to detect a short.

    So even if you only draw 200mA...

    I beg to differ: I'd keep R2. It makes sure the FET stays "entirely off" while the Arduino reboots or is flashed or if you accidently turn the pin to an input. If you leave it floating, it may load...
