Teensy 4.0 Microcontroller – Arduino Compatible Dev Board

The Teensy 4.0 Microcontroller is also one of the speediest little development boards we’ve seen! A fantastic platform for your Arduino projects, the Teensy 4.0 provides a 32-bit cortex that rockets your processing speeds to a whopping 600MHz. Although not technically Arduino, this tiny board integrates with Arduino programming easily using the Teensyduino add-on software and giving your projects a bigger level up in performance than even the Uno or Mega can provide. We are so impressed with the amount of IO pins and interfaces available on the Teensy 4.0. If you’re also a tinkerer enthusiast, ideas are likely already springing to your mind.

A Teensy can fit itself into numerous creative ideas. Its generous 2048K flash and 1024K RAM, plethora of peripherals, and small size make the Teensy 4.0 perfection. Craft wearables that dabble in machine learning, mechanical keyboards, and PC case mods. Teensy can even slip into a Raspberry Pi project or two. Here’s a glimpse of what else makes the Teensy 4.0 the ultimate choice for Makers and innovators:

• Rocket-Fueled Performance – At its core, the Teensy 4.0 boasts an ARM Cortex-M7 processor clocked at a staggering 600MHz.
• Bucketload of Pin Interfaces – The Teensy 4.0 is more than packed with pins. With 40 digital pins, all interrupt-capable, and 14 analog pins (plus 2 ADCs on chip), you'll have the versatility to connect and control a vast array of sensors and devices. On top of that, 31 PWM pins and 32 DMA channels awaits.
• Memory to Spare – With a generous 1024K of RAM (including 512K tightly coupled), and a whopping 2048K of Flash memory (with 64K reserved for recovery & EEPROM emulation), you'll have all the space you need to store your ideas and innovations.
• High-Speed USB Ports – Enjoy the convenience of two USB ports, both blazing at 480MBit/sec.
• Onboard RTC – Keep track of time and date with the onboard RTC (Real-Time Clock), ensuring your projects are always synchronized with the real world.
• Teensyduino Wide Compatibility – Reach perfect harmony with your Arduino projects. The Teensy 4.0 has comes with open-source Teensyduino add-on software that makes it compatible with the best of Arduino.

Whether you're building robots, IoT devices, audio projects, or anything your imagination can conceive, the Teensy 4.0 is your trusted partner in creation.
