About this item

The Teensy 4.1 Development Board with Headers is a high-performance, feature-rich microcontroller platform built for demanding embedded applications. Powered by the NXP iMXRT1062 ARM Cortex-M7 processor running at 600 MHz, it offers exceptional speed and processing power in a compact form factor. This version comes with pre-soldered headers, making it ready for use with breadboards and socketed connectors—ideal for rapid prototyping and development. Teensy 4.1 significantly expands upon the capabilities of the 4.0 version by adding more I/O pins, a built-in Ethernet PHY, microSD card slot, and USB host port. It includes 8MB of flash memory, 1MB of RAM, and two QSPI memory pads for optional external memory expansion. It supports dynamic clock scaling, allowing the CPU to change speeds without affecting peripheral timings—perfect for power-sensitive applications. With 35 PWM outputs, 14 analog inputs, 8 serial ports, and compatibility with the Arduino IDE via Teensyduino, the Teensy 4.1 is ideal for advanced projects involving audio processing, robotics, automation, and networking. The included headers save time and effort, making it the perfect choice for developers seeking a plug-and-play high-performance microcontroller.
