Teensy 4.0 Development Board

Teensy 4.0 Development Board (ARM Cortex-M7, 600 MHz)

The Teensy 4.0 features an ARM Cortex-M7 processor running at 600 MHz, powered by the NXP iMXRT1062 chip, making it one of the fastest microcontrollers available today—up to ten times faster than the Teensy 3.2. The iMXRT1062 is a cross-over processor, offering microcontroller functionality at microcomputer-level speeds. It is ideal for applications requiring large flash memory, high RAM capacity, intensive data processing, dual high-speed USB support, and even integrated graphics processing.

When operating at 600 MHz, Teensy 4.0 consumes approximately 100 mA of current.

Teensy 4.0 supports dynamic clock scaling. Unlike traditional microcontrollers, changing clock speed does not affect serial baud rates, timing functions, or audio sample rates. Arduino functions such as delay() and millis(), along with Teensyduino features like IntervalTimer and elapsedMillis, continue to work correctly while the CPU speed changes dynamically.

A built-in power shut-off feature allows the 3.3 V supply to be completely disabled using the On/Off pin and a pushbutton. When a coin cell is connected to VBAT, the onboard RTC continues tracking date and time even while the board is powered off.

Teensy 4.0 can also be overclocked well beyond 600 MHz.

Teensy 4.0 uses an ARM Cortex-M7 processor running at 600 MHz with the NXP iMXRT1062 chip, delivering extremely high performance for embedded systems.
