[Help]Adding leds to Poker3{Solved}
« on: Thu, 27 July 2017, 19:27:48 »
Hi all,
I really need your help.
I have a poker3. I hope to add backlight to my keyboard. And I bought 100pcs 2x3x4 white led (20mA).
Now I solder some of them to PCB and test it. I found I can not light up those LEDs.
Is there anyone can help me? I really appreciate.

This is a tragedy. This is a disaster. When I soldered all, I realized that I made a mistake. Anode and Cathode are exchanged. I think Poker3 PCB PCB mark is misleading. I should solder the cathode of led to the positive mark "+" on PCB.
Sad  :'( :'( :'( :'( :'( :'( :'( :'( :'(

well u can cut the traces where they begin,  and flip it with copper wires,

this might be less work than desoldering all of them and resoldering.
