Hey, sadly i did not figure out where the problem was, iirc i unsoldered almost every part directly connected to ground and the short was still there. No progress since then sadly

Haha Yeah, nice word joke. I unsoldeted u4 and Also q1, still shorted. But now 10Ohm resistance from ground to 3.3v

Wouldnt it make sense that it's the bootloader Chip itself? Since it's not booting at All even when the 3.3v still exist

Hello wondering which board would be best to use together with teensy 4.0 and/or 4.1. I would need to play some songs at the "same" time, like they overlap and dont stop the song already playing. The board should include the amplifier on it, like the DFPlayer. Sadly experiencing heavily...

Okay, soooo you would guess its some of the ICs?

Uh im really unsure why I wrote that. Im Sorry. Here again bulleted to make it clear: 3.3V is shorted to GND (diode tester beeps) 3.3V to GND is at 16-19.5Ω when turned OFF (varying because of heat after it was on) 3.3V to GND is at 0Ω when turned ON (always) I tried many combinations for the...

I attached some images of my teensy 4.1 I also cleaned the board with some chemical pcb cleaner to make sure no dirt shorts somewhere. I measured again and still have a voltage drop of 0.0mV over all GND pins together and/or the 3.3v pins together. Measuring from 3.3v to GND results in 0.0mV...

Yeah, thats the problem im at right now. I have used this board as a Joystick(keyboard) at some time and it worked all time long fine. Just grabbed it again and wanted to use it. No reaction. I a bit experienced in this electronic stuff and understand what you mean. It atleast should...

Does someone have another idea how to save it? Would like to recover my 40€ microcontroller haha

Its me again. I tried measuring what you said but always get 0.0mV. Only 0.1mV between both 3.3v pins.

No, the pc doesnt even detect the board, also I have a fairly fresh windows install, my laptop also doesnt recognize it. Other teensy 4.1 or 4.0 do work. Also no LED lids up when trying to press the boot button

It seems like the full 3.3volts are there. Input voltage is 4.7volts. I guess because of the hot parts which draw a big amount of current due to the 15 ohms between 3.3 and 0v. Thats weird Any other idea?

So there's 15 ohms from GND to 3V3. Regarding to the schematics there are 13 smd capacitors and 1 resistor in between those two pins, also U2, U3, U4 and U6. How would I start finding the broken one? De/resoldering each after another? Edit: seems like R7 is not connected between 3v3 and GND, my...

Nah I dont have a infrared camera. Also im not very sure how to find where the short comes from. Unsoldering parts and checking if they are in good condition?

Hey everyone! Just chosed a random of my many teensy board, but It didnt turned on at all. Then I realized that U2 is getting very(!) hot. Also Q1 is extremely hot. After that I hooked up my multimeter to check if any pins are shorted, sadly I realized yes. 3.3V is shorted to Ground. Does...

Okay, thank you! Have a nice day :D

Hello Guys and Girls, I accidentally rid off the ferrit bead from my Teensy 4.1 at the back with the Position "L2" and the name "Ferrite l20" What exact ferrite bead is this so I could replace it and reuse my teensy? Thanks! Unhappy

What exactly is low? And Do you have a tutorial or explanation how to do it

However, there are words that are longer. haha

I heard that the resistors are getting really fast really warm. Any way to avoid grilling them in time?

But is there a way to measure resistance without any voltage? Like a Multimeter does

Version 4.1 in my case

Okay, so a teensy would be able to do that? By measuring voltage to calculate the resistance? Like the Arduino can.

Hey, my current project is to add a indicator stalk for simulators like Truck Simulator 2. The stalk however works with resistance, which increases or sink when I press or move buttons. Thats the only way I know for now

Is it possible to measure the resistance like given in this Tutorial? https://create.arduino.cc/projecthub/iasonas-christoulakis/how-to-make-an-arduino-ohm-meter-90fda8 Thanks!
