Teensy 4.0 (RT1062)
Overview
The Teensy 4.0 (RT1062) is a compact development board built around the NXP RT1062 ARM Cortex-M7 32-bit microcontroller. It provides a high-performance MCU in a small, breadboard-friendly form factor intended for embedded prototyping and evaluation. The board plugs into the Teensy ecosystem and is commonly used where real-time processing, DSP, or USB device functionality is required.
Why Choose This Part
Choose this board when you need a very capable 32-bit MCU in a tiny, ready-to-use evaluation form factor. The Teensy ecosystem provides a large collection of libraries and community support that speeds development of USB, audio, and control applications. Its small size and breadboard-friendly layout make it easy to integrate into prototypes without building a custom carrier board.
Applications
Key Specifications
Getting Started
Program the Teensy 4.0 using the Arduino IDE with the Teensyduino add-on or use PlatformIO for project-based workflows; install the Teensy Loader application to upload builds over USB. For lower-level development or MCU-specific debug, you can use NXP toolchains such as MCUXpresso. Start with a USB A-to-micro or USB-C cable (depending on the board variant), example sketches from the Teensy website, and the community libraries for audio, USB, and peripherals.
Also Consider
NXP Semiconductors
- The raw RT1062 MCU used on the Teensy 4.0; choose this if you want to design a custom board with the same Cortex-M7 performance.
STMicroelectronics
- A high-performance Cortex-M7 MCU with an extensive ecosystem and many package/peripheral options for demanding embedded applications.
