GLCD Backlight - not as bright as expected

Submitted by michael@de on Sun, 04/05/2014 - 08:50

Hi Guys,

just assembled my GLCD-Kit (V1.5) but the glow of the backlight was not as bright as expected.

To assemble the GLCD I used the emonGLCD Build Guide

http://openenergymonitor.org/emon/modules/emonglcd/buildguide13

Checking the schematic and boardlayout I found out the following error in the Build Guide:

The picture in step 7 shows R3 (100) and R9 (4k7) are interchanged.

A simple placement error :-)

Michael

Hmm. You didn't follow the build guide, did you ;-)  The pictures at Step 3 and Step 4 are correct!  However, thanks for pointing it out. I've added a note below the picture.

I've worked Gimp's magic on the picture, and there's no need for the note any more.
