Question: nRFMicro 1.1 LEDs D2/D3 orientation

[Raskilas]

Hi, my question might be silly and outdated, but which orientation should I use for LEDs D2 and D3 on nRFMicro 1.1 board?

Are you kidding me. It's all there in the picture. Front has matching green on my picture and on yours. I only look at the front. Don't look at the back, back is different. Also see https://lighthouseleds.com/blog/polarity-guide-of-0402-0603-0805-1206-and-most-all-smd-leds.html Mind that LEDs don't have to blink by default, adafruit bootloader knows nothing about pin 1.10. The easiest way to check leds is probably Circuitpython, https://github.com/joric/nrfmicro/wiki/Circuitpython

Sorry for confusion, I meant where there is Cathode and Anode on board. It's NOT question about FRONT/BACK orientation, it is about "Cathod on TOP of D2 or on BOTTOM and cathod on TOP of D3 or on BOTTOM". I just attached front/back pictures in case if someone in future won't be able to check back side of his/her LED.

There are standard footpints. Key (bracket) on the silk is Cathode (minus). It usually goes to ground via load resistor.

Thanks! I've checked your first answer edition history and saw point to serigraphy bracket, but this comment is much more clear.
