Product Showcase: Teensy 4.1

[@Spacedog49]

I've already ordered mine for a high speed rocket flight control/IMU/datalogging project.

[@Jxmiecole]

Me too, how did your flight controller go?

[@Spacedog49]

@@Jxmiecole 90% of my previous flight controller software transported directly over to the Teensy 4.1. I am having some issues reading the stored data in the 4-bit mode. I believe I need to update my SDIO libraries. I had to stop work on the project to prepare for three launches conducted last week. The data analysis from those launches will keep me busy for a couple of months. I'm already receiving inquires on when I'll publish my findings.The data dart flights with the Teensy 4.1 won't launch until early 2021.

What a beast, awesome work Paul, now if he would just get on youtube and do some videos on it.

[@pauloterenzi]

Hi, Paul, thank you for all the information you gave to us. I'd like to know if I can use Teensy 4.1 to turn my guitar's pickup Arduino project into a USB audio interface to record directly on the computer. I don't know anything about electronics: I'm just trying to figure out a starting point. Any suggestion from you would be super helpful. TIA.

[@mmdnaderi7183]

my arduino is embarrassed watching this

[@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?

[@JackOHaraEngineering]

11 months ago, but you’re definitely gonna want a servo driver board.

[@Build_the_Future]

What about interrupts?

[@rednassie1101]

This Teensy is almost more powerful than a Raspberry Pi zero haha

[@TheDroneOperator.]

can this handle two arducam 5mp cameras recording video at 1080p 30fps?

[@UKsystems]

This is dependent on the actual amount of processing and specifications needed for your coder run during this so you have to work that out

[@DoctorX17]

I feel like the only things this guy is missing is GPS and cellular

[@priyanshujindal4397]

What is the boot time of teensy 4.1?

[@ColonelXZ]

How many cores does the processor have?

[@hzrnbugsie]

Unless you're doing some audio or graphics processing on this, it's almost an overkill for just about any MCU application.

[@ivanravenski]

Yes.

[@rajatmond]

You could run an indefinite RNN on MCUs. With more power, you can make your model complicated. Actually that's why I'm considering this.

[@CW_CW_CW_]

Actually it is good to run any kind of complex real-time algorithms (like PSO, genetic, artificial neural networks) in any MCU application. For example for optimizations regarding power electronics or communications (or both like power line communications where I am mostly intererted in).

[@robn2497]

Inverse kinematics is what im going to do on it. I guess you could call that gfx.

[@gordonpayne8601]

I had an unexpected DRIVE IN MOVIE FLASHBACK! When you paused the video for the "Let's all go to the Lawwwby" song, I remember being 4 years old, sitting in my Dad's grey Plymouth Valiant, with the clunky drive-in speaker hanging on the window glass on a warm summer night! Ahhhh..thanks! Amazing looking board!

[@cw4608]

Gordon Payne The dancing soft drink, popcorn, and candy bar. Wow what a flashback! :). Happy times

[@AlexusDelphi]

Can this be used to make a larger than normal PC keyboard?

[@halasimov1362]

Buttons.. Yeah it can do buttons.

[@Brad_Jacob]

Would this be good for a DIY midi controller?

[@element4element4]

Yes, although this is too over powered for a midi controller. Might even be too fast for most conventional multiplexers that are often used for midi controllers (you can use more expensive faster multiplexers instead). For a midi controller in would use teensy 3.6 or even less. The teensy 4.1 would however be very good if you want to build some digital audio system that requires a lot of heavy calculations.

[@redtag7648]

Hello sir , im a student from pakistan working on a project which i need Teensy 3.6 or 4.1 . I search for this in pakistan but hardly i find one site where it;s too expensive i need your help can u send me this teensy i shall be very thankfull to you

[@sblantipodi]

But why all those features without WiFi? What should I do with this thing without WiFi?

[@danjones7783]

Internet comment sections - is it satire/sarcasm or is it serious? Mysteries...

[@sblantipodi]

@@danjones7783 don't get it, is teensy 4.1 WiFi enabled?

[@danjones7783]

@@sblantipodi No. It's got a 10/100 ethernet PHY for cabled connections. Not every application needs embedded WiFi, and from a certification aspect, I can understand why not including a WiFi PHY.

[@ytfp]

There is plenty of room for wifi (multiple if need be)if you need it. This has enough io for pretty much all wireless standards that exist for a microcontroller really. Not everyone needs wifi and to keep cost (and power) low there is none, but there is no reason why you can not add your own.

[@sblantipodi]

@@ytfp it would be great to know how many people will use this module without WiFi. I personally prefer modules with built in WiFi.

[@psubond]

Ok, got my beer, take your time.

[@p10rambo]

can you actually get 100mbps? say i want to serve files from a usb drive through ethernet with this

[@SembeiNorimaki]

Yes, 100 milli-bits-per-second is a very slow speed (takes 10 seconds to transmit 1 bit). You can get faster speeds making a fire and sending smoke signals.

[@p10rambo]

@@SembeiNorimaki what about pigeons?

[@vfxstudio2265]

operation voltage??

[@sagar73594]

3.3 v

[@SoCalFreelance]

A teensy amount of RAM, but yes, it's only $27 so I understand. However, if you look at a modern smart phone teardown you see their motherboards aren't much bigger than the Teensy, yet they have a fast snapdragon processor, GB's of SDRAM AND GB's of eUFS storage (watch 'The Samsung Galaxy Note9 Teardown'). Perhaps create a super-Teensy with those specifications for AI vision or speech recognition applications.

[@lolllolol5416]

Teensy is a microcontroller, not a sbc.

[@hzrnbugsie]

There's already the Raspberry Pi for that kind of spec. The question is, are you courageous enough to code baremetal (no Linux OS) on it?

[@SembeiNorimaki]

You are comparing a microprocessor with a microcontroller. It's like comparing apples and oranges

[@mohandmohand2047]

Is it work for wii u????

[@EFIELDIQ]

Great engineer

[@EFIELDIQ]

Field IQ 🔎

[@squirlmy]

OMG, did you let KZbinrs talk you into wearing plain old boring engineer's work clothes! Those bastards! I say let your freak flag fly!

[@AndreasDelleske]

Sadly, no power over Ethernet so it needs two cables and a wallwart. Apart from that, awesome. Doom is going to be ported to it in 3.... 2...-

Demn Good!
