RGB LED Shield diagrams for documentation purposes

17 Dec 2014

For those creating projects with the RGB LED ShieldRGB LED Shield, hopefully these images can come in handy.

They are attached to the bottom of this post in two versions - white background and transparent background.

I can't take credit for the Arduino Uno diagram, I found that on the Internet (not sure of the original source, it was in many places - and just edited it slightly).

Hi Parker, Can you try the program called RGBLED_2_SAFE.ino ? I tried that, with LEDs connected to the red channel only, and they worked, see the post here: RGB LED Shield from Infineon - Getting Started…

Yes that file did not seem to have anything to hookup to. But shabaz 's Inkscape file worked once I deleted the big white rectangle from it.

I do not beleive there is a minimum current limit for the Infineon board, it is simply the set constant current in the demo sketch, the board is actually programable for almost any current up to the MAX…

I'm back! I am still having trouble, I am waiting on a 300mA rated bulb to come, but I am using resistors in order to get the current down to 20mA in order to allow me to use a regular 5mm Red LED. I am using a 9V battery to power my board. I know it is rated for 12V-48V so I do not know if the 9V is just not enough to power the driver, or what? I have voltage across the light, and it will light up, only when i am trying to measure the resistance and the multimeter's leads touch it, but the light never turns off, or dims.

I do not beleive there is a minimum current limit for the Infineon board, it is simply the set constant current in the demo sketch, the board is actually programable for almost any current up to the MAX of about 700mA per channel I beleive and up to 40V ish supply, th eboard is degined to drive the LEDs directly with NO seriese resistors, you can get it to work with LED strips or other LEDs with series resistors but the results are not ideal, just functional

so using the default sketch and a little iddy biddy LED, you will have a high probability of frying it instantly (20mA vs 300mA), you will need to adjust the configured settings at the beginning of the sketch

I believe I covered this topic off when doing the IOT of holiday lights challange, see here http://www.element14.com/community/groups/arduino/blog/2014/12/15/byob-party-re-configuring-the-infineon-for-regular-12v-led-strips

Hope this helps

Peter

It's handy to know that there is a 300mA minimum current limit. Connecting an LED for testing sounds otherwise feasible.

My problem is that my LED is not rated for 300mA or higher, silly me! I completely overlooked this requirement. As expected it was user error. Thank you for your help.

Hi Parker,

Can you try the program called RGBLED_2_SAFE.ino? I tried that, with LEDs connected to the red channel only, and they worked, see the post here: RGB LED Shield from Infineon - Getting Started Guide

There is a video at that URL that shows how the wiring looks like (two wires going to the LED, and two going to a 9V supply, so basically exactly what you're trying to do I think.
Perhaps your LED is connected in the reversed direction? Anyway, good to use the unmodified RGBLED_2_SAFE.ino code as mentioned at that link, to confirm everything is working well.
Also, can you confirm your red LED rated for 300mA or higher? (A small typical red LED is not).

Hopefully these suggestions can help.
