Hairline power traces - good concept, poorly made
Valarian, 18.06.2019
I like this board for its high amount of connectors in a compact space.
Visually appealing, clear arrangement of elements, good quality PCB.
This could be a quite nice busboard.
But here the pros end.

- It's a power distribution board. With superthin copper traces. Why? This means an unnecessary high impedance. There's plenty of unused space for appropriately fat conductors on the board. Racks with around 20 modules easily draw more than 1 amps, which can easily cause serious voltage drops across weak traces, especially at the outermost plugs. Modules with insufficient and/or asymmetrical pos / neg voltages will introduce distortion.

- Solder joints are quite often weak / 'cold' on my piece. This will cause single lines to fail sooner or later or at least have bad contact. Depending on the module construction, some might even take damage. For example, when there's each voltage connected, but GND open, the current will most probably take a path it shouldn't; module makers rely on a correct supply and omit protection circuitry most of the time.

- Description states "active removal of PSU ripple noise". In reality, it just features small 47µF capacitors, which just filter passively, at most. "Active" in this context usually refers to some more complex electronics, which is misleading in this case. You still _need_ a _clean_ supply.

- Description states "short circuit protection". In reality, it features three self-resetting fuses of 1.85A, so it is an over-current protection. Which is fine. However, I didn't test whether the weak traces even withstand 1.85 amps long enough for the fuses to trigger or just burn; I'd assume that the fuses will hardly trigger - or not at all. At 12 volts, the trace needs to withstand a surge of 22 watts.

I wouldn't recommend this board to modular folks who just want things to work well and reliably, since it has (in my opinion) notable electrical design flaws, for no real reason - not cost, not complexity. Nano just failed to give power lines reasonably fat traces.
Except the massive GND ground plane. lel.
