What is Teensy? Arduino Compatible USB Development Board

Teensy is an Arduino Compatible development Board.

It's a complete USB development board that requires no programmers or special cables.

What distinguishes Teensy is its small size and ease of programming and configuration.

 

Since it has its own on-board programmer and can be connected to PC or Macintosh using the standard USB cable used with most smartphones.

There are many versions available with different processors speeds and memory space.

For example, 

Teensy 2.0 is based on ATMEGA 32U4 8 bit AVR Microcontroller with speed of 16Mhz

While

Teensy 3.6 is based on Freescale 32 bit ARM Cortex-M4 processor with 180MHz speed

With full specs of

• 180 MHz ARM Cortex-M4 with Floating Point Unit
• 1M Flash, 256K RAM, 4K EEPROM
• Microcontroller Chip MK66FX1M0VMD18 (PDF link)
• USB High Speed (480 Mbit/sec) Port
• 2 CAN Bus Ports
• 32 General Purpose DMA Channels
• 22 PWM Outputs
• 4 I2C Ports
• 11 Touch Sensing Inputs

What makes Teensy special from any other board?

Arduino compatibility makes a great advantage for any development board.

But most Arduino compatible boards come with limited capabilities like speed, memory and peripherals.

That makes the requirement of additional shields essential.

 

Other non Arduino compatible boards come with many features and connectivity but require special software and tools to learn.

That's what made Teensy Boards special.

Where you have a powerful USB development board fully compatible with Arduino IDE and collaborated previously written code.

How to program Teensy with Arduino IDE?

You can use it with Arduino IDE. Only but with this special software that enables Arduino IDE to program Teensy called TeensyDuino.

After installing TeensyDuino, you can find Teensy support in Arduino IDE menus as usual for any Arduino compatible board.

All tools and examples can be found on the designer website.
