The Teensy USB Development Board is a complete USB-based microcontroller development system. Version 3.5 features a 32 bit 120 MHz ARM Cortex-M4 processor with floating point unit. All digital pins are 5 volts tolerant. All Teensy boards are shipped assembled and fully tested.

The Teensy is a breadboard-friendly development board with loads of features in a, well, teensy package. Each Teensy 3.5 comes pre-flashed with a bootloader so you can program it using the onboard USB connection: no external programmer needed! You can program for the Teensy in your favorite program editor using Coryou can install the Teensyduino add-on for the Arduino IDE and write Arduino sketches for it!

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, 120MHz 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 four separate interval timers, plus a delay timer! Oh yeah, and all digital pins have interrupt capability and are 5V tolerant.

All of this functionality is jammed into a 62.3mm x 18.0mm board with all solder points on a 0.1 grid so you can slap it on a breadboard and get to work! The Teensy 3.5 is larger, faster and capable of more projects, especially with its onboard micro SD card port. An upgraded ARM Cortex MCU (120MHz from 72MHz), more memory (512K from 256K), as well as more RAM, EEPROM and accessible pins make up the key new features of this teensy board. The Teensy 3.5 is slightly scaled down from the Teensy 3.6 but is offered at a cheaper price point, comparatively.
