Teensy 4.1 Development Board with NXP Semiconductors iMXRT1062 Cortex-M7

Description

The Teensy 4.1 is a powerful development platform built around the NXP Semiconductors iMXRT1062 ARM Cortex-M7 processor, operating at an impressive 600MHz. This iteration significantly expands on its predecessors, offering four times the flash memory of the Teensy 4.0 and provisions for additional external memory. Designed with a form factor identical to the Teensy 3.6, it delivers enhanced I/O capabilities, including a built-in Ethernet PHY, an SD card socket, and a full USB host port, making it suitable for complex embedded applications requiring high-speed connectivity and data handling.

One of the standout features of the Teensy 4.1 is its support for dynamic clock scaling, allowing the CPU speed to be adjusted on-the-fly without disrupting critical timing functions like serial baud rates or audio sample rates. This flexibility is crucial for power management and optimizing performance in various operational scenarios. Furthermore, the board integrates a power shut-off feature, enabling complete power disablement via a pushbutton, while a coin cell connected to VBAT can maintain the RTC for accurate timekeeping during power-off states. The Cortex-M7’s floating-point unit (FPU) provides hardware acceleration for both 64-bit “double” and 32-bit “float” operations, significantly boosting computational efficiency for demanding mathematical tasks.
