Description: The Teensy is a breadboard-friendly development board with loads of features in a, well, teensy package. Each Teensy 3.2 comes pre-flashed with a bootloader so you can program it using the on-board USB connection: No external programmer needed! You can program for the Teensy in your favorite program editor using C or you can install the Teensyduino add-on for the Arduino IDE and write Arduino sketches for Teensy!
The processor on the Teensy also has access to the USB and can emulate any kind of USB device you need it to be, making it great for USB-MIDI and other HID projects. The 32 bit processor brings a few other features to the table as well, such as multiple channels of Direct Memory Access, several high-resolution ADCs and even an I2S digital audio interface! There are also 4 separate interval timers plus a delay timer! Oh yeah, and all pins have interrupt capability. Also, it can provide system voltage of 3.3V to other devices at up to 100mA.
All of this functionality is jammed into a 1.4 x 0.7 inch board with all headers on a 0.1" grid so you can slap in on a breadboard and get to work! The Teensy 3.2 adds a more powerful 3.3 volt regulator, with the ability to directly power an ESP8266 Wifi, WIZ820io Ethernet, and other 3.3V add-on boards that require a little more power. Additionally, if it is used within the Teensy 3.1 limits of operation, the Teensy 3.2 and 3.1 are interchangeable!
Note: This does not come with a USB cable, please check below for an appropriate one.
Dimensions: 1.4 x 0.7" (~35 x 18 mm)

MUCH faster than 8-bit AVR Arduino boards. I recommend combining the Teensy 3.2 with the Sparkfun Teensy shield board. The result can be used as a direct alternative to several Arduino models. The Teensyduino extension to the standard Arduino IDE is superb.

First, the specs and price on these little boards couldn’t be better.
But the main reason I love Teensy so much is that the “bootloader” is contained in a separate chip from the main MCU. The loader is placed in RAM from the secondary chip when you press the programming button, but otherwise isn’t even in flash on the main MCU.
This means that if you drop the Arduino stuff, you have access to 100% of the resources of the MCU completely under your control. That might not be your cup of tea, but it’s refreshing to find hobbiest dev boards unencumbered by hobbiest bootloaders.

It’s a flexible and powerful board, with huge capacity and small size, for me it is the best option for make projects.

Everything this hardware hacker and professional software developer needs.
Love it! Easy to use and code examples for interrupts are available. Unlike the Feather and SAMD21 which are just about useless except for blinking some LED’s.
Some distrib’s are spiking the price + 30% or more.
Cheap, powerful and easy to prototype!
I was up and running within minutes with Teensy. It’s also very cute.
Teensy isthe ideal product for most of my projects. I’m happy to see this update and the possibility to work more easily with the ESP8266 wify module.
I’ve been using Teensy since the 3.0 kickstarter. I’ve rolled them out into several projects. They work well. They are well support with the Arduino Libraries. I recommend them.
