Teensy USB Development Board

Update: Due to limited chip supply for Teensy 3.x, PJRC is discontinuing pins soldering for all Teensy 3.x products. As we are able to get the chips, we'll continue making these boards without the pins soldered.

Actual size is 2.4 by 0.7 inch

The Teensy USB Development Board is a complete USB-based microcontoller development system.

Version 3.6 features a 32 bit 180 MHz ARM Cortex-M4 processor with floating point unit. All digital and analog pins are 3.3 volts. Do not apply more than 3.3V to any signal pin.

All Teensy boards are shipped assembled and fully tested.
