KC868-A16 LED Output - cyberrailpete - 05-22-2025
Hello.
Working on a project with LED output necessary. Have loaded your firmware if I turn on any put on 9-16 LED light up...Connected to output 9
Ground of LED on 9 common on 3v.

i don't understand.

I have an LED wired into output 9...the LED common + is wired into 3V the -/ground is working into output. If I toggle output 10 the LED lights up same for 11,12 etc etc when I only want it to work on output 9

A16 output 12-24V DC, not output 3V DC. i suggest you draw a diagram on paper how you wire, so that we can understand you.

The board has a 3v3 pin no?! The output pin is it outputting 12v positive?
This works perfectly well on an Aurdino surely same can be done with your board?

Interesting issue! I'm also working on a similar LED project. Have you tried checking if there might be a shared ground problem between outputs 9-16? Could help narrow down the firmware vs wiring issue.
