Title: MOD-RGB question
Post by: kristsp on November 26, 2015, 07:23:04 AM
Hi!

I looked at MOD-RGB module description in your web page. It says that it has short-circuit protection on LED channels. Looking at board schematic I am not quite sure how it is set up. Low side N-FETs that switches LEDs does not seem to have over current protection on their own. Although there are sense lines to micro controller (analog inputs I guess) through diodes. Are these used for short circuit detection and how that works?

Thanks for your advice, :)
