Overview
The Teensy 4.1 is the latest and most powerful version of the Teensy development platform, designed for high-speed and real-time applications. Powered by a 600 MHz ARM Cortex-M7 processor (NXP iMXRT1062), it offers substantial improvements over its predecessor (Teensy 4.0), including 4× more flash memory, enhanced I/O capabilities, and additional expansion options such as Ethernet PHY, microSD socket, and USB Host support—all while maintaining the same compact footprint as the Teensy 3.6.
This board is ideal for developers needing advanced performance, real-time capabilities, and Arduino IDE compatibility
Key Feature
- Ultra-fast ARM Cortex-M7 processor at 600 MHz
- Dual-issue superscalar architecture for high instruction throughput
- Tightly Coupled Memory (ITCM/DTCM) for single-cycle memory access
- Floating Point Unit (FPU) with support for 32-bit and 64-bit calculations
- Dynamic clock scaling without affecting serial/audio timing or Arduino functions
- Power management with push-button on/off and RTC battery backup
- Expandable memory support with two optional chip locations
- Built-in USB Host, microSD card socket, and Ethernet PHY
- Optimized for Teensyduino with Arduino library support
- Overclockable beyond 600 MHz for high-performance applications
