Hello Teensy folks!
I have a teensy 4.0 with an audio-shield (rev D) and I would like to build a reverb euro-rack module with them. So far, I'm testing with the example code that uses a freeverb node.
I'm powering it at 5V. I noticed that at 600Mhz it would draw over 180mA and when clocking it at 24Mhz, it would still draw around 100mA. I'm very confused why this happens as it is suggested that power-consumption should be less than 10% of that.
I measured it by putting my multimeter in series with the 5V line. I tried both the 5V line from my eurorack synthesizer, which can only supply 100mA. So initially when running the teensy at 600Mhz, it would fail after 20 sec because the voltage regulator couldn't take it anymore. Now I'm testing with USB and I also tested it with a L7805 connected to the 12V line to give me 5V.
I verified that the teensy is working. I've been experimenting with it and I would not be super surprised if I damaged it in some way, but that doesn't seem to be the case. I was hoping that at 24Mhz, power consumption would be much lower (say around 30mA).
Can it be that the audio shield is drawing a lot of current? Not sure if I can test it without, because the code does depend on it.
Some help would be highly appreciated!
