## Description

The Teensy 4.0 is a high-performance microcontroller development board powered by the NXP iMXRT1062 ARM Cortex-M7 processor running at 600 MHz. Despite its compact 35.6 × 17.8 mm (1.4 × 0.7") form factor — the same size as the Teensy 3.2 — it delivers exceptional processing power with a dual-issue superscalar architecture, hardware floating point (32-bit and 64-bit), and 1024 KB of RAM (512 KB tightly coupled). Teensy 4.0 supports dynamic clock scaling, allowing speed changes without affecting serial baud rates, audio sample rates, or Arduino timing functions. A power shut-off feature lets you completely disable the 3.3 V supply via a pushbutton, with an optional coin cell on VBAT to keep the real-time clock running. Key Features 600 MHz ARM Cortex-M7 – NXP iMXRT1062, dual-issue superscalar with branch prediction 1024 KB RAM – 512 KB tightly coupled memory for fast single-cycle access Hardware FPU – Accelerates both 32-bit float and 64-bit double operations Dynamic Clock Scaling – Change CPU speed without disrupting timing or serial communication Power Shut-Off – Hold a button for 5 seconds to disable the 3.3 V supply; RTC continues on VBAT Overclockable – Supports speeds well beyond 600 MHz Teensy 3.2 Compatible – Same form factor with broad pin compatibility Specifications Processor – NXP iMXRT1062 (ARM Cortex-M7) at 600 MHz RAM – 1024 KB (512 KB TCM + 512 KB general) Flash – 2048 KB Current Draw – ~100 mA at 600 MHz Operating Voltage – 3.3 V (5 V tolerant digital inputs) Board Dimensions – 35.6 × 17.8 mm Ideal For Audio synthesis and DSP applications High-speed data acquisition and real-time processing USB MIDI controllers and instruments Robotics and motion control Note: Headers are not included and must be purchased separately and soldered on.
