AudioShield and built-in LED

[sschiesser]

Hi,

I was wondering if I can physically disconnect the built-in LED on Teensy 3.6. Since pin13 is used for the audio shield (I2S_DOUT), I cannot simply disable it in software, but would like to save some current.

Didn't find anything in the forum (strange actually)...

Thanks for any help,
Sebastien

You can still unsolder the LED itself or the 470R resistor. But is it really worth the effort for <= 4mA ?

Thanks for the tip! And yes it is worth with embedded systems, where every mA counts
