The Teensy 3.5 is a breadboard-friendly feature-packed development board designed by PJRC and pre-flashed with a bootloader. This allows easy programming using the onboard USB connection without the requirement for an external programmer. The Teensy can be programmed in C or via the Arduino IDE by installing the Teensyduino add-on.

The NXP Kinetis MK64FX512VMD12 Cortex-M4F microcontroller on the Teensy 3.5 has the ability to emulate any kind of USB device, making it ideal for USB-MIDI and other HID projects. The 32-bit, 120 MHz K64F microcontroller also offers multiple channels of direct memory access, several high-resolution ADCs, and an I2S digital audio interface. There are also four separate interval timers plus a delay timer. Additionally, all digital pins have interrupt capability and are 5 V tolerant.

All of these features are included on the 62.3 mm x 18.0 mm board with all solder points on a 0.1" breadboard-compatible grid. It also offers an onboard micro SD card port. An upgraded ARM® Cortex-MCU (120 MHz from 72 MHz) and more memory (512 K from 256 K), as well as more RAM, EEPROM, and accessible pins make up the key features of this "Teensy" board in relation to the prior Teensy 3.2.
