3.0 has been replaced with 3.1 - which is even better and awesomer! We've got a few of these remaining, in case you want to pick them up at a discount. Once they're gone, they're gone!
Teensy 3.0 is a small, breadboard-friendly development board designed by Paul Stoffregen and PJRC. Teensy 3.0 will bring a low-cost 32 bit ARM Cortex-M4 platform to hobbyists, students and engineers, using an adapted version of the Arduino IDE (Teensyduino) or programming directly in C language.
Based on a 32 bit ARM chip, Teensy 3.0 aims to greatly increase the computing capability and peripheral features, but maintain the same easy-to-use platform that has made Teensy 2.0 so successful.
Please note: Teensy 3.0 and 2.0 are not official Arduino-brand products. Although the Teensyduino IDE has been adapted so that many simple Arduino projects will work with the Teensy, there will still be a lot of libraries and shields that will not work with this device! If you're new to microcontrollers, they suggest going with a classic Arduino UNO since all Arduino projects, examples and libraries will work with it.
