Teensy 4.1 // MCU Monday

The new Teensy packs all the I/O and memory that wouldn't fit into the 4.0 – with a 100 Mbit Ethernet PHY, USB host capability, and built-in SD card socket. Wow!

Thanks, Alex! I've been evangelizing for Teensy 4.0 since its release. Time for everyone to advance from basic Arduinos. For near the same cost (or less in some cases), maker projects should be sporting ESP32, RISC-V -based like Sipeed MAix BiT, or Teensy 4.x, all of which are Arduino IDE compatible. So much more performance and capability for the buck.

This vid convinced me to order one! Thanks for the info.

You have any issues with Teensy devices not working after a computer wakes from sleep? Struggling to figure out what it's getting hung up on. Had to install a powered USB Hub to so I could power cycle the board.

@2:32 "I think the sound nerds among us will be especially excited."

Yup...I just ordered 10 of these! :)

Can the teensy 4.1 control all of those 35 PWM pins at the same time? Would it be able to control 35 servos at once?

[mannytuzman]

I don't see pins on the 4.1 and you say its great on a bradboard.
I dont know if I will need a brad board with the 4.1.
Please show how to connect IF IT IS

Is it possible to use Teensy board as a passive USB device, which can be controlled by a Python program running on a UBUNTU machine talking to other boards?

[lescollier]

Hi have you found a nice rugged enclosure as yet ideally ip65 or ip67 ??

[peterlambert]

I am looking for a Teensy for my new Moonlander keyboard. Have you any suggestions?

[brenta]

Gorgeous! (I'm referring to the board, of course!😏)
Great development. Teensy is awesome.

[mannytuzman]

Can I do simple midi in AND midi out from the teensy 4.1 without any added components????

I am not an engineer.

[alexwright]

Has any one tried using the SPI for connecting a fast ADC say 16 bit 200Khz sank rate upwards?

[bennguyen]

So the Teensy 4.1’s external Ethernet board on oshpark has the Magjack for the transformer/magnetics.. but where is the DP83825 PHY chip?

[EvilDaveCanada]

Can you imagine the 'Super' keyboard you could build with this??

[keiphilinstrumental]

Is this can also work for building MIDI controller?

[priyanshujindal]

Can you tell me what is the boot time of teensy 4.1?

[Cyberplayer]

That is great it looks like the same footprint as the Teensy 3.6!

[kentharris]

Does the board have a built in Real Time Clock?

[pranavmokashe]

how to reset teensy board using external Reset button?

[tswdev]

Shouldnt the USB and micro sd be on the same side?
