Teensy 3.1 is a project born out of crowdfunding using Kickstarter and has become important in embedded projects that need both power and a smaller size. It is a development platform based on a 32-bit ARM Cortex M4 processor. It is implemented in the form of a board so that it can be set up in protoboards and programmed with Arduino and C language. Given its type of microcontroller, it can be identified as a keyboard or USB mouse, which offers numerous possibilities. It addition to being very powerful, it is compatible with most Arduino libraries.
It can be used directly with the Arduino IDE (Integrated Development Environment) using the Teensyduino add-on available on the manufacturer's website (link below).
