Teensy 4.1 from Digikey. With or Without Ethernet ?

[skpang]

Digikey has Teensy 4.1 in stock now but it doesn't say whether it is with or without ethernet.

I assume it is with ethernet ?

Paul, please confirm.

If you read the item description, it's the same as the SparkFun Mfg # 16771, which is here:

Having recently bought a ton of these from SparkFun, it is a Teensy 4.1 without headers and without the ethernet jack.

I wasn't referring to the ethernet jack. More referring to the ethernet PHY.

On PJRC.com there are versions with and without ethernet.

Interesting, that's news to me that PJRC has started manufacturing both versions. I just checked the SparkFun 16771 stock that I have and it has the ethernet.

Sparkfun should soon have the version without ethernet.

I hadn't noticed that, but given the parts shortage, I can imagine offering a version without the ethernet phy.

And if your SMT soldering skills are rusty or non-existant, you can get pre-soldered versions of the Teensy that includes soldering in the psram, flash memories, and ethernet pins:

In looking at the above, I didn't realize larger flash memories (128MB/1 gigabit and 256MB/2 gigabit) flash chips are now supported, compared to the older 16MB/128 megabit flash memory.

Is there an image that shows the physical location of the Ethernet PHY chip on the board? Looking to be able to confirm whether it is present with a simple visual inspection. Thanks.

The Ethernet PHY chip is designated by U6:
