Teensy 4.1 // MCU Monday

what's up Baxter's welcome to MCU Monday we have an exciting new board for you this is the teensy 4.1 it's just come out from Paul Stauffer gin & Co so this board compared to the teensy 4.0 it's basically the same board but upgraded with all the i/o and memory that you wouldn't be able to fit on this little guy there's a couple of little ports soldering spots rather for memory chips and there's more about that on the tnz 4.1 page that we'll look at in a second one of the most obvious new features is this SD card slot for micro SD cards it's gorgeous I'm really excited about this one it's gonna be really low latency for use and you have your usual reset button the chip on here is the same it's an NX p ida MX 1060 or RT 1062 and it is an ARM Cortex m7 600 megahertz I think so it's really low latency for lots of audio applications plus it's got a ton more GPIO pins and it's very breadboard friendly so where you can just look at the number of breadboard friendly pins on this one versus this one and you can see that it has a lot more to offer so let's take a look at the website so here we have the Parc Store pj RC comm slash store slash teensy 4-1 HTML you get a close up of the board you get the whole pin out here and it's pretty incredible so we have pictures showing how to connect the ethernet up as I mentioned it has this Ethernet physical layer that is a first for the teensy boards and there is an ash Park project where you can download this adapter but they're also planning to release it as a kit and one of the other cool new things about this board is that it has a USB host capability so whereas the teams before when Oh already you were able to connect devices to it as a use USB host now it has the power management available so that you can just do that on the fly so they have a picture here showing how you can connect up a keyboard to it you can connect many musical instruments to it and Mouse other stuff um I think joysticks and things anything that you have over USB you'll now be able to plug it directly into your teensie I think the the sound nerds among us will be especially excited about this besides the fact that the low latency enables lots of other things so for example one suggested use for this is artnet based LED projects so this will be able to run really large-scale LED projects in fact they've already run some benchmarks showing just testing the speed over ethernet and the speed of the chip so these are not necessarily tests that include actually running an real life project so you know your mileage may vary as always but they're pretty confident about the speed of this new board it's very cool and it has low latency compared to some dedicated mini PCs and things like that you can check out the pin Orla the chip specs here you've got five pins with power management for USB as we mentioned that 100 megabit physical layer the microSD socket you've got 35 PWM pins which is outrageous you've got 18 analog inputs 8 serial ports that's one up from the teensy 4 8 megabytes of flash memory you've got two chips for a Q spy memory that's if you choose to add those own you already have a bunch of memory I think it's one megabit o one megabyte of RAM already built into the chip and then if you need extra you can add those two extra chips for I think PS Ram you suggested and flash memory whatever you need you can add it let's make sure that my screen share is working because I get paranoid yes great well so we got checks notes SD card socket USB host port oh yeah other suggestions for using that Ethernet physically which has I Tripoli 1588 precision packet time stamping so your application should be very robust and able to deal with you know timing artnet LED projects streaming audio open sound control so open sound controller OSC is something that various devices may use I've used it with the muse brainwave detecting headset to control things with my friend muhib there's more information here that I've linked below about the built in MX RT 1062 chip you can check out all the specs on that and then there were a couple more things that he mentioned an email that aren't quite on this page but just more info about what kinds of applications this is good for I'll let you stare at the pin out while I look at that Paul says the microcontroller on teensy 4.1.1 has one mag of RAM built-in for many real-time control projects the internal Ram is plenty but some projects can greatly benefit from the added memory frame buffers for high resolution TFT displays are the most common years so little screens thin film transistor LCD screens I think allowing advanced graphics rendering large memory is also very useful for special effects like advanced reverb buffering fast incoming data before logging to an SD card and for emulation of retro computer systems like classic arcade games who doesn't love those and there was one more thing I guess Paul's own summary of this board is that not every project requires so much i/o or extra memory teensy 4.0 fills those needs but when you do need more i/o more memory and fast ethernet or connecting USB devices or fast SD card access the larger 14 Z 4.1 brings this extra IO capability to a platform designed for real-time use with fast 600 megahertz m7 performance so yeah as you can see it is a little bit larger then the previous teensie 4.0 we've got this little guy this is the 4.0 this is the 4.1 you know this one's a little bit bigger but it's still teensy like look at this compared to an Arduino Uno or whatever but who know would be like yay big say it's still teensy this one is flat on no it's not flat on the bottom it's got some surface mount components down here actually you can see all the details of course in the close-up photos on the teensy 4.1 product page linked below Wenger says how are you getting shipments in lockdown well the mail is still working here and we just quarantine things in the garage for three days so that they don't have anything left on them Jay says you can never have enough pwn pins thanks Jay love your new cool goggles everyone go check out odd Jay on Instagram and Twitter he's doing some amazing stuff with animatronic face mounted goggles and he's blowing up it's so cool xavier says great content as usual thank you oh thank you yeah really excited about this one a lot of the pins that were available just on the bottom of this board as solder ball pads are now actually broken out as GPIO pins and that's just really exciting so go check out the teensy 4.1 you can order it today Congrats fall in the next launch and yeah as always hack on
