  • Teensy 4.0 USB Microcontroller Development Board
  • Provides support for dynamic clock scaling
  • Supports Arduino timing functions
  • Is designed to allow dynamically speed changes
  • Also provides a power shut off feature
  • Can be overclocked, well beyond 600 MHz

The Teensy 4.0 USB Microcontroller Development Board is the latest Teensy, offering the fastest microcontroller and powerful peripherals in the Teensy 1.4 by 0.7 inch form factor. Teensy 4.0 provides support for dynamic clock scaling.

Unlike traditional microcontrollers, where changing the clock speed causes wrong baud rates and other issues, Teensy 4.0 hardware and Teensyduino's software support for Arduino timing functions are designed to allow dynamically speed changes.

Teensy 4.0 also provides a power shut off feature. By connecting a pushbutton to the On/Off pin, the 3.3V power supply can be completely disabled by holding the button for 5 seconds, and turned back on by a brief button press. If a coin cell is connected to VBAT, Teensy 4.0's RTC also continues to keep track of date & time while the power is off.

Fast Shipping, Original Product

Thank you robotshop for fast shipping and processing


Arrived this morning, great packaging!


Quick delivery. Very powerfull device for a good price.

Gread Dev board for the price!!

I'm surprised at how small this dev board (the length is almost less than an inch) and even more when it did run in 600mhz. Overall, this is a great value and will recommend to everyone who wants the best performance dev board in early(Q1) 2020.

Great performance in a small package!!

I am building a self balancing robot and, but wasn't able to achieve the cycle times I wanted with the Arduino Nano. The software of the robot that I was trying to emulate was running on a Rasp Pi, but I didn't want that added complexity, so I tried the Teensy 4.0. Running at 600mhz I immediately noticed a vast improvement in the stability performance of my robot. The only thing to watch for is the Teensy 4.0 is not 5volt tolerant so you may have to use logic level convertors. Also, there is plenty on documentation on https://www.pjrc.com/teensy
