PJRC Teensy 4.0 iMXRT1062 Microcontroller Development Board

Teensy 4.0 is the latest Teensy microcontroller development board from PJRC, offering the fastest microcontroller and powerful peripherals in the Teensy 1.4 by 0.7 inch (3.6 x 1.8 cm) form factor. It features an ARM Cortex-M7 processor at 600MHz, with a NXP iMXRT1062 chip, the fastest microcontroller available today. Teensy 4.0 is the same size and shape as the Teensy 3.2 and retains compatibility with most of its pin functions. The NXP iMXRT1062 is a 'cross-over' processor, which has the functionality of a microcontroller at the speeds of a microcomputer. It's perfect for when you need lots of flash, RAM, to crunch lots of data, or when you need two full speed USB ports. It even has a built-in graphics processor! 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 dyn
