CGS114 Serge DUSG LEDs and driver questions

2016-05-17 by guymccusker

I'm about to build my first CGS114 DUSG. I've seen a few people mention that the module runs better with low-current LEDs rather than standard ones.


First obvious question: is that true?


Second question: if it is a good idea to use low current LEDs, what changes are needed to the driver circuitry? Obviously a higher value current-limiting resistor would be in order, but what about the base drive resistor?


I am keen to get good values from the outset because I hate desoldering and I understand the boards can be delicate too. Any hints will be very much appreciated!
