Do i need to do something special to have external power to this board to the 5v pin and if i want to plug in a usb at the same time?
Do I have enough room on this board to put a simple 3 image animation .gif (thumb nail size) with out the need to add a micro SD card?
does this have keyboard and mouse HID support like the 3.6?
which pin set (spacing) do I need with this board?

Easy, fun little board, but overpriced IMO

With this board you get 3 CAN busses (when you add a transceiver, typically a $5 board per bus) and an easy to use Arduino experience. Plenty of IO, plenty of power. I've been amazed at how much this tiny little thing can handle. I started out with a simple CAN application, then realized I could drive long LED strips, and do BT stuff all on the same board at the same time.It's flexible, power efficient, and tiny. FlexCAN_T4 is a fantastic CAN library - clean and straight forward, using simplified interface. I am more of a Swift/Kotlin/Java guy and the simpler the library, the more likely I am to build something cool. I got up and running with CAN bus stuff faster and cheaper on Teensy than I did with RaspberryPi and Python.Back to the value question - As a sort of high performance catch all device, many using it for audio applications, it's going to have features you do not need. It's sitting between an RPi and traditional Arduino. For my exact application this means it's slightly over priced since I needed to pile on more and more accessories to get to something like an ESP32 which wifi and dual mode bluetooth for a fraction of the total cost. Even a Nano IOT starts to make me wonder why I picked a Teensy. Performance is the biggest trade off.One thing you cannot put a price on though is the ease of use. If I waste hours messing with a shoddy complicated board, optimizing code so it fits or runs better on a less capable board, how much is that really worth? So I can move faster and create more interesting things without worrying about specs, but It's a double edged sword. Teensy is cost prohibitive if you start trying to productize your creation built upon it, even if to make a few copies. Make sure you really need the power and most of the features before committing to it. Otherwise there are cheaper options with different features that might fit better.

Super-fast and Super-features!

Until recently I worked with all sorts of Arduinos: Uno, Mega, Nano, and Pro. A month ago I started a new project that required microsecond-timing and decided to use a Teensy 4.0. The result: I am blown away by the incredible speed of the Teensy, which I am estimating to be 10-100 times faster than that of the Arduinos. It is like entering a new world in which I need not fear writing CPU-intensive functions. Those are a drop in the bucket, not even noticeable when working with a Teensy 4.0. This, combined with the order of magnitude bigger memory space available on the Teensy make programming fun again. Forget about struggling to work around the Arduinos' resource limitations.I am also extremely impressed by the extensive documentation on the Teensy developer's website (pjrc dot com). There are tens of libraries optimized for Teensys' spectacular performance, code examples, explanations, diagrams, and most importantly, a very active and helpful user forum.After I installed the Teensyduino add-on (it took maybe 15 minutes) I could upload sketches straight from the customary Arduino IDE, without any problems. Except that the uploads are much faster with the Teensy than they were with the Arduino.I could go on heaping praise on this little marvel, but I am too eager to get back to my Teensy project. I want to add, though, that I am not affiliated with Teensy in any way, nor have I received any kind of freebies. I am just a genuinely thrilled user.

Awesome little board

I just got my little BoardForth running on a Teensy 4.0. Holy cow ... that board is fast! Not as fast as my PC, but MUCH faster than the other boards I have tried. As in, at least 100x faster the ATMega2560. And probably 10x faster than the Seeeduino XIAOU, Redboard-Turbo, and ESP-8266. I know, apples and oranges, but still. It's crazy.I am loving Teensy. I have 2 of them now: the LC and the 4.0. They just work. I use the Arduino IDE. I had all these problems with the STM32F411 board - no problems at all with this.I just hope I don't brick it when I solder the pins on.

A great board

Overall an awesome development board. Great support on the PJRC website, and good user community. Works well with the Arduino IDE and libraries.My only (very minor) issue is not breaking out the CAN3/FD pins on the headers - you can still get to them, but you have to solder wires to pads 30 and 31 on the bottom of the board. If you absolutely need CAN3/FD pins on the headers, get a Teensy 4.1 which has those pins broken out to the headers (and a microSD slot, and capacity for adding more memory).

So pretty, so powerful, so awesome

These microcontrollers are simply the best.I work in power plants on many types of controllers, I'm doing an upgrade using a European made PLC to develop an HMI, same chip drives them. This is a serious piece of hardware for not a lot of money.Paul is the man!

Works great for my sound triangulation project

It was touch and go for a while since I was porting the code from someone else's project which used the Teensy 3.0 because I wanted some future-proofness. I finally debugged the issues with help from a great GitHub developer.

Fast, but very complicated behind the scenes

With the Arduino IDE, the programming is fairly easy, but comes at the great disappointment of code bloat. The full compiler directory is about 800 megabytes. Granted, that a lot of that is code libraries and examples, but just look at the compiler messages- huge amount of files being checked just to run the blinking LED demo, which takes well over 7K of code in the Teensy. The Teensy chip itself is very complex with huge amounts of documentation just for the on-board peripherals, and incomplete documentation for ARM/Thumb instruction set. For someone who just wants quick results from their microcontroller, the Teensy works great, but for purest like me who want to know what is happening at the assembly/hardware level, it is too complex. K.I.S.S.
