What I found on the web is that the ILI9341 draws about 60mA .
That seems reasonable so I guess your multimeter is off.
Did you set the multimeter to DC current ?

Found a potential solution in this thread.
When I uploaded this code into a Teensy 3.2 and click "Restart Port" in USB Device Tree Viewer, I see the onboard LED go off and on.
Powering the Teensy by 5V externally ,...
Yes, I agree with Bricomp's suggestion.
Teensy boots very fast, so one needs to insert some waiting time for the nvidia jetson to finish it's boot procedure.

Perhaps you should comment out these 2 lines and try again:
Serial.println(F("Hello Teensy 3.6 dual CAN Test."));
Serial.print("CAN bus 0: "); hexDump(8, inMsg.buf);

Does this help?
I changed to :
void midisend(){
for(int y = 0; y <=2047; y++) {
if (abs(midivals) != abs(newpos / 4) % midiquant){
if (midiquant == 128){
midivals = abs(newpos / 4) %...
Hmm, I'm confused too (but more in the sense that I probably do not understand you fully).
My feeling is that some index is just off by 1.
Would you mind sending your full code? Or the most basic code that shows the...
I guess that a value of 0 is illegal, but don't know what issues this causes.
What I actually wanted to say is that you think you sent to channel 2 but actually you sent to channel 1.
By the way, I see that...
Checked the design once more, but still got those 6 wire stub warnings...
Not sure why I get these warnings and you don't... Anyway, go for it! (standard disclaimers apply though :) )
Success,

On the schematic: I see that you use only 1 signal to drive all 4 FET's. Is that indeed your intention? I'm asking because you have signals PY2, PY3 & PY4 on Teensy pins.
On the board layout, I see 5 wire stub...
Yes, those airwires are really showing an issue: Eagle tells you that those pins are not electrically connected.
But before reordering the PCB, I first would measure whether these pins are indeed not connected by...
Was able to open your project.
It complained about some missing libraries though.
Even with hitting the ratsnest button and filling in the copper planes, it still complains about airwires:
Also the schematic...
Could you also send the schematic ? Or preferably the whole Eagle project?
Findings issues from only the .brd is nearly impossible...
By the way: I see a whole bunch of not routed airwires...

Teensy 4.1 does not have a DAC pin so it can't output an analog signal to the PropShield for amplification.
The audio input pin on the PropShield:
Teensy 4.1: instead of a DAC output like on Teensy 3.2, the pin...
@SteveSFX: the OnSemi 74VHC595MX does not have TTL-compatible input levels.
So, if you want to use it as a levelshifter as well by powering the part from 5V, like wramsdell suggests, it is not guaranteed to work with...
It seems like resistor R8 is broken. From the bottom of this page:
Its value is 100kΩ and it pulls down the enable signal from the processor to the TPD3S014 current-limit switch for the USB host power. See the...
