Adafruit Teensy 3.1 + header

Teensy 3.1, a compact and breadboard-friendly development board by Paul Stoffregen and PJRC, seamlessly enhances processing power with its 32-bit ARM Cortex-M4 platform. An ideal choice for diverse projects, it integrates smoothly with the Arduino IDE (Teensyduino) or can be programmed directly in C.

Building upon the success of the Teensy 3.0, this version expands capabilities with 64K of RAM, 256K of Flash, and 5V tolerant digital inputs. The 12-bit DAC, dual ADC, and CAN bus support establish it as a versatile upgrade, perfectly compatible with any previous sketches designed for the 3.0 model.

The Teensy 3.1 is a remarkable leap forward, providing increased computing capacity while maintaining the user-friendliness associated with Teensy 2.0. It features 21 high-resolution analog inputs, 34 digital I/O pins, 12 PWM outputs, and options like USB with dedicated DMA memory transfers and I2S for high-quality audio interfaces.

Its robust specifications include 3 UARTs, SPI, I2C, IR modulator, an RTC with optional crystal and battery support, and 16 independent DMA channels, making it an essential tool for innovative engineering and experimental creation.
