About this item

The Teensy 4.0 Development Board with Headers is a compact, ultra-fast microcontroller platform designed for high-performance embedded applications. Powered by the NXP iMXRT1062 ARM Cortex-M7 processor, it runs at 600 MHz, making it one of the most powerful boards available in its size. This version comes with pre-soldered headers, allowing for immediate use with breadboards and socketed systems—perfect for prototyping and rapid development. Despite its small size (35.56mm x 17.78mm), the Teensy 4.0 delivers impressive capabilities, including 2MB of flash memory, 1MB RAM, and support for dynamic clock scaling, allowing the processor to adjust speed without affecting timing-critical functions like serial communication or audio sampling. It features digital and analog I/O, PWM, and multiple serial interfaces (UART, SPI, I2C), enabling a wide range of connectivity options. Compatible with the Arduino IDE via Teensyduino, it also supports advanced features like real-time audio processing, USB HID (keyboard/mouse/joystick), and overclocking. The Teensy 4.0 with headers offers unmatched performance in a compact, breadboard-ready form factor—ideal for developers, makers, and engineers building high-speed, real-time embedded systems.
