K8061 1 LED broken and "RUN"-LED blinking

Hi there,

thank you for the helpful contributions in this forum. I hope someone can help me, too.

I have 2 problems with the Interface I’ve just finished soldering:

  1. Unfortunately, one LED in my K8061 KIT is broken. What LED do I need to replace it (V and mA)?

  2. When I connect the card with power supply (in fact I had no 12V power supply so I used a 9V battery), LED 1-8 (LD 13-20) glow constantly but the “RUN”-LED (LD12) is blinking and not glowing constantly. Does that denote an error? What does this mean?

Unwary, I left out “Power ON”-LED (LD10). When connecting it to the PC Demo and Diagnosis say “USB connected” but “CPU FAIL”. I’ve uploaded a photo for it might help you helping me;-) fotos-hochladen.net/view/img … b6814k.jpg it is huge though.

Thank you for your support in advance.

Hi,

I don’t want to offend but your soldering needs some help.
You need to resolder all of the joints so the pad is covered and the solder flows.
A 9 volt battery will not work you should get a 12 volt power supply that can provide 300mA or above.

Here some similar cases and solutions:
