PJRC Teensy Microcontrollers

Teensy 4.0 microcontroller

The Teensy is a complete USB-based, breadboard-friendly ARM microcontroller development system in a very small footprint designed by Paul Stoffregen at PJRC. Using an ARM Cortex M-4 microprocessor running at up to 600MHz, the Teensy is the fastest microcontroller available today.

Each Teensy comes pre-flashed with a bootloader so you can program it using the on-board USB connection: No external programmer needed! You can program the Teensy in your favorite program editor using C, or you can install the Teensyduino add-on for the Arduino IDE and write Arduino sketches for Teensy.

The Teensy development platform also includes shields and adapter boards, such as an audio adapter shield, to expand the capabilities and functionality of the Teensy microcontroller.
