Wicked fast and tons of memory. Easy to bring into the Arduino ecosphere.
Arduino compatible, but in a totally different speed and memory league. I love the SD slot, and will use this for high speed data collection. Very high quality design and build.This is the first Arduino compatible board that I wasn't immediately wanting for more power / memory. I hope PJRC keeps this up. It would be nice to have wifi.My main issue is that the pin numbers are not on the silk, nor are they in any way easy to find The pin numbering is very counter-intuitive. Very frustrating, easy to fix aggravation.No pullups on the IIC bus. The SCK for SPI is shared with the built in LED. This DOES NOT WORK for multi slave SPI application - spent hours troubleshooting till I pinned SCK out on an adjacent pin. Not getting the logic in that at all, considering the high number of overall pins.

Another amazing product from Paul Stoffregen
Definitely not your father's Arduino. Paul takes it to the next level. More powerful and breadboard friendly than the Teensy 3.2, and the microsd card reader is a big plus. Buy it with pins installed if your a soldering novice. Get the 3.5 in you need 5V tolerant logic.

wishing for tolerance
I bought 2 within 1 month, enough said. Pick up alot of level shifters the pins are not 5v tolerant!

A lot of features normally found in accessory modules
When I first started working with Arduinos I bought the cheapest ones. Over time I found that it's not cheaper because you end up buying extra modules to get the functionality you want for various projects. This microcontroller has most of the features you need for Arduino projects you find on the web.

Small powerhouse on the cheap
I love these things.I'm no stranger to the limits of an average Arduino, and I've tried several alternatives, such as MBed, but for the most part I end up back with my old friend the 328p.However, I ended up discovering Teensy after ordering some PCBs, and haven't looked back since. Normally I just buy 3.2s, but I needed a USB Host controller, so I grabbed a 3.6. It works perfectly, and the thing is crazy fast. Combined with the small form factor and bountiful ram, it's hard not to fall in love with these little guys. They're cheap too!

Need for speed.
I needed some very specific pulse readings and this is the only dev board I could find that could read/write to pins fast enough. Very glad it exists

Serious boot problem
I bought several of these before I figured out that they have difficulty booting up when powered separately from USB 5V. We had to add a chip reset delay circuit to make the boot reliable. Unreliable boot is not something you want on a device that is used as a controller. It needs to be reliable without human monitoring. Hopefully this problem will get fixed in the next rev of Teensy boards. Aside from that, I really like these Teensy devices.

Very happy
This has been a pleasure to work with! The Teensy community is very helpful, and programming the board is simple if you've used Arduino-C before. Make sure to fix the board somewhere while you're working on it; the board is very small and the weight of the USB cable will probably slide it right off of your desk.
