This is excellent advice! Thank you! Whether ultra low noise or not, at least your recommendations are way to add multiple external devices safely, without hitting the 250 mA limit on the 3.3 V power rail of the Teensy. I’ll keep all this in...

Thank you for all the excellent information! I am wishing to use a high quality 3 pin linear regulator (made specially for audio use) to power the Teensy audio shield. Would a MOSFET connected to the 3.3v power output to the of the Teensy...
