The Teensy 4.0 development board is a state-of-the-art microcontroller board equipped with an ARM Cortex-M7 processor, achieving an impressive clock speed of 600 MHz. It is based on the NXP iMXRT1062 chip, which is considered one of the fastest microcontrollers on the market. The board retains the same size and shape as its predecessor, the Teensy 3.2, and offers high compatibility with most pin functions. With a power consumption of about 100 mA during operation at maximum speed, it is suitable for a wide range of applications. Support for dynamic clock scaling allows for flexible adjustment of CPU speed without issues related to baud rates or other time-dependent functions. Additionally, the board features a convenient power shutdown function that can be activated with a simple button, and it maintains the date and time through a connected coin cell battery, even when the board is powered off.
