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.

This lockable version of the Teensy 4.0 is suitable for commercial products and secure applications to protect your program code from unauthorized access and coping.
