The Teensy 4.0 is the fastest microcontroller development board available, featuring an ARM Cortex-M7 processor running at 600MHz. Built around the NXP iMXRT1062 chip, it delivers exceptional performance in the compact Teensy form factor (35.6 × 17.8mm) while maintaining pin compatibility with Teensy 3.2. Fully compatible with Arduino IDE through Teensyduino, with support for dynamic clock scaling, real-time clock with battery backup, and hardware floating-point for both 32-bit and 64-bit operations. Key Features 600MHz ARM Cortex-M7 – Dual-issue superscalar processor with branch prediction 1024K Flash / 512K RAM – Tightly Coupled Memory for single-cycle access Hardware FPU – Accelerates both 32-bit float and 64-bit double calculations Dynamic Clock Scaling – Change CPU speed without affecting timing functions Real-Time Clock – Battery backup support via VBAT pin Power Control – On/Off pin for complete 3.3V shutdown with button hold Overclockable – Can run well beyond 600MHz USB Device – High-speed USB with multiple device types Specifications Processor – NXP iMXRT1062 (ARM Cortex-M7) Clock Speed – 600MHz (overclockable) Flash Memory – 1024KB (plus 64KB recovery) RAM – 512KB tightly coupled + 512KB general Current Draw – ~100mA at 600MHz Operating Voltage – 3.3V (5V tolerant digital inputs) Dimensions – 35.6 × 17.8mm (same as Teensy 3.2) Ideal For Audio processing and synthesis projects High-speed data acquisition Real-time signal processing USB MIDI and HID devices Performance-critical embedded applications Note: Headers not included – purchase separately and solder as needed.
