So i soldered together the prototype and the ENIG revision, its time to test the light.

First the prototype.

The hoped "backlight effect" is there, but the way the LED´s shine through the PCB looks vey unsatisfying. Maybe if i would have blocked the light a bit more with a full groundplane.... 🤔

Anyways, another lesson learned. On to the star of this show.

And woah, the LED´s are much stronger than i anticipated. We can also already see another mistake i did: the copper of the coil is surrounded by an silkscreen-free area. Thus the light also shined through between the trace.

But on the bright side (*badum tss*) we also got a pretty cool backlight effect.

Putting the PWM input way down <10% seems optimal and i´m quite happy with the outcome. Also we only draw around ~10mA, thats a plus.
