Is there any specific tool that i could use to determine if packets are being sent? if i assemble a second board could i plug them into each other and read the received packets?

After getting help with Serial communication issues from this great forum I finally got my Custom Teensy 4.1 board working! I'm able to Program it finally and was eager to test my Ethernet connectivity with the DP83825L Ethernet PHY IC (U5 on my layout) and the J1B1211CCD RJ45 Connecter (P1 on...

after speaking to the guy who initially designed the custom layout, he also had difficulties with the SP0503's which is why he stopped using them! but unfortunately didnt update his design with the component changes, and now uses the SP3003-02JTG diodes which actually work.

The Data lines behaved how you said when i probed them but when i pulled off the ESD diodes it worked perfectly. thanks so much for all the help everyone, i have finally made my own custom teensy and can't wait to expand on this knowledge for bigger and better things!

Thanks for the reply, I misspoke when I said host, I’ve been using USB 1 the whole time. The diodes are for ESD protection on the data lines, I believe the teensy 4.1 schematic has them as the TPD35014. The custom teensy I based my board on also used them and they worked according to the...

What should i see when i probe my bootloader on my Custom teensy 4.1 Design? the blink sketch flashes but the USB descriptor fails so i cant program it at all. i have broken out the JTAG pins for the bootloader on my board and wanted to understand what i should be seeing to pinpoint my problem...

Ive designed and assembled my own teensy 4.1 with ethernet, and USB-C instead of micro. The Bootloader flashes the blink script to the memory and it executes properly which is the most success I've had in months, I'm ecstatic! However my windows PC wont recognize the teensy and gives the 'error...

I've designed ordered and assembled 2 teensy 4.0 custom PCBs in strict accordance to the 4.0 schematic with no real design changes as this was to test myself as I have never undertaken such a complex PCB. The GitHub link with the files are here. After assembling the 1st Teensy board the TLV7533...

Hi all, I created a custom PCB following the Teensy 4.0 schematic and have assembled it, however when testing the board it gets stuck in the power up sequence and no 3.3V is outputted from the regulator. i have tried replacing the chip and making sure there are no short circuits between the...

Thankyou so for the help! it was a bit counter intuitive at first removing vias while at the same time adding them and moving them for better plane connections, but once i actually did it i found it made a lot more sense. i moved the caps beneath the processor and found a few traces that didn't...

Hi All, I wanted to ask here if anyone could critic my PCB layout for a Custom Teensy 4.0? I have had some experience in PCB design but nothing this complex. I tried to route the traces by order of their sensitivity to outside sources and the PJRC guide for custom Teensy 4.x was extremely...
