About this item

The Teensy 4.0 Development Board is a compact, high-speed microcontroller platform built around the powerful NXP iMXRT1062 ARM Cortex-M7 processor, running at 600 MHz. Despite its small footprint (35.56mm x 17.78mm), the Teensy 4.0 delivers exceptional performance, making it suitable for real-time audio processing, complex control systems, and fast data acquisition tasks. It features 2MB of flash memory, 1MB RAM, and supports dynamic clock scaling, enabling efficient power management without disrupting timing or peripheral functions. Unlike traditional microcontrollers, Teensy 4.0 maintains accurate timing even when CPU speed changes—thanks to tight integration with Teensyduino, the Arduino-compatible development environment. Teensy 4.0 supports hardware-based floating-point math with both 32-bit (float) and 64-bit (double) precision, offering accelerated performance in mathematical and DSP applications. It includes 40 digital I/O pins, 14 PWM outputs, and multiple serial interfaces, all in a compact board perfect for space-constrained projects. While it lacks the additional I/O expansion features of the Teensy 4.1 (like Ethernet and USB host), the Teensy 4.0 excels in size-to-performance ratio. It's a top choice for developers needing raw processing power in a small, efficient, and versatile form factor.
