Product description: Teensy 4.1 ARM Cortex M7 - Arduino compatible - SparkFun DEV-16771
Teensy 4.1 manufactured by SparkFun. It features a dual-core ARM Cortex-M7 processor clocked at 600 MHz with an NXP iMXRT1062 chip. The board's flash memory is 8 MB, which is up to four times that of the previous version of the Teensy 4.0, and it also provides more I/O capabilities, including an Ethernet PHY, microSD card slot, and USB host port. This version does not have goldpin connectors soldered in. The Teensy 4.1 also comes with a built-in RTC that works by connecting the lozenge battery to the VBAT pin.
Dynamic clock scaling
The Teensy 4.1 board draws up to 100 mA of current and provides support for dynamic clock scaling. In practice, this means that it has been designed in such a way that changes in clock speed do not significantly affect the data rate.
