Just finished building Slopes and Envelope. Gorgeous modules and they work great. I prefer blue LEDs on ST Modular modules, on these two there are LED driven by LM321MFs. Is there a way to reduce the brightness by adding or changing a resistor somehwere?
On Slopes the LED I want to change is LED_CLK. I've tried adding a resistor in parralell between IC_LED5 pin 4 and the LED anode, and between the cathode and R65. These had no apparent effect on the brightness.
