Teensy 3.1 is a small, breadboard-friendly development board designed by Paul Stoffregen and PJRC. Teensy 3.1 brings 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. Teensy 3.1 is an upgrade over 3.0: now with 64K of RAM, 256K of Flash, 5V tolerant digital inputs, 12 bit DAC, dual ADC, and CAN bus support. Teensy 3.1 is a drop-in replacement upgrade for 3.0 and can run any sketches designed for 3.0.

Based on a 32 bit ARM chip, Teensy 3.1 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.

Technical Specifications:

32 bit ARM Cortex-M4 72MHz CPU (M4 = DSP extensions)
