Teensy 4.1 // MCU Monday

[@BigMTBrain]

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.

[@e-pi5189]

The teensy 4.0 looks so beautiful. I bought additional ones just so I don't ruin the gold solder pads.

[@jakemandoshkin7065]

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

[@EricFontaineJazz]

@2:32 "I think the sound nerds among us will be especially excited." Yup...I just ordered 10 of these! :)

[@MsCuriousturtle]

Thank you for the intro!

[@mannytuzman3461]

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 NECESSARY......Thanks

[@Nazarus007]

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.

[@TheClickMonger]

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?

[@BenBilesBB-box]

but why no SWD or JTAG debug pins :(

[@alexwright6038]

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

[@mannytuzman3461]

Can I do simple midi in AND midi out from the teensy 4.1 without any added components???? I am not an engineer.

[@2kBofFun]

A Teensy 2 will do that (or a Leonardo)

[@EvilDaveCanada]

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

[@pranavmokashe1637]

how to reset teensy board using external Reset button?

[@gurbanliye]

Connect to usb (power), push the reset button.

[@gurbanliye]

Read the section : On / Off Pin and Power Control

[@brenta1905]

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

[@VoiceOfAsh]

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?

[@lenhumbird]

Nice intro. Thanks!

[@itaisavin1596]

How many i2c channels does it have?

[@Cyberplayer5]

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

[@robertcameronjones]

Different pinout tho.

[@peterlambert5130]

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

[@lescollier2467]

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

[@bennguyen1313]

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?

[@CrazyLogic]

it's on the 4.1 board.

[@keiphilinstrumental2017]

Is this can also work for building MIDI controller?

[@HacksterIo]

Yes! Teensy is a popular choice for MIDI controllers, as well as HIDs such as a mouse, keyboard, or joystick.

[@AlexusDelphi]

Would this be good for making a double sized PC keyboard? Like 210 buttons

[@HacksterIo]

I don't see why not! The Teensy series is very popular for custom keyboards. :)

[@AlexusDelphi]

@@HacksterIo Alright, cool. Everyone's been focusing on other features, but not so much how crazy you can make the keyboards :P

[@priyanshujindal4397]

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

[@robertsutton3666]

1 blink :)

[@kentharris7427]

Does the board have a built in Real Time Clock?

[@gurbanliye]

www.pjrc.com/store/teensy41.html -- Section Timing (it says ) : Two crystals prodvide accurate timing. A 24 MHz crystal is the basis for the system clock and most peripherals. A phase locked loop (PLL) increases the 24 MHz up to the system clock speed. A separate 32.768 kHz crystal is used for the Real Time Clock (RTC). If a coin cell is added to VBAT, the 32.768 kHz oscillator continues keeping date/time while main power is off.

[@tswdev]

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

[@gurbanliye]

Yes they are on the same side, but what is the point here ?

[@pranavmokashe1637]

how to reset teensy ? like a reset button

[@JaapioNL]

Teensy doom?

[@ashk3343]

wow

[@AndreasDelleske]

Awesome but no Power over Ethernet. Sigh. So we need 2 cables...

[@tde04014]

Teensy is not for Poe things, the poe functionality is anyway on the ethernet-cable board, only a small special PCB with a voltage regulator.

[@mcchickenandham]

GPIO’s up the Ying yang gang !

[@charlesmagill4932]

No offense, but you look like the villain from a 90's JRPG.

[@splashinglures]

but its got no wifi

[@shadow7037932]

Not everyone needs WiFi. 80% of my projects don't need Wi-Fi. Besides you can easily add WiFi by using a ESP32 or similar.

[@CrazyLogic]

I don't need WiFi, but could add this easily if i did - have a look at ESP8266 - it wont be long before someone will post about how they added wifi for a project.

[@e-pi5189]

It's more for crunching numbers and controlling a lot of I/o

[@quadbyte]

main problems with teensy 4.1 are: no wifi, and only supported Arduino, no Linux support. Does not make sense in 2020

[@CrazyLogic]

hummmm - kinda a different product market really. I have projects that need realtime control, not linux.... the 4.1 looks like the answer to a product for my needs. if you need wifi and linux - look at a Raspberry PI....

[@AndreasDelleske]

ESP32 / 8266 covers this well..

[@quadbyte]

@@AndreasDelleske agree, teensy is old fashioned now

[@quadbyte]

​@Subhojit Bose thanks, I have chosen ESP32, even if I thought teensy had a better hardware. Teensy Problem was his designer was only focus on Arduino, which is the worse framework ever if you want something a bit industrial

[@tde04014]

Again teensy and arduino is not indended for industrial use, but if your want more professional ui your can use platform io.

[@salamdrik]

Is there a way to record usb signals that go into it, and Replay like a macro. Like to connect mouse or Steering wheel and after can replay it
