Teensy 4.1

Teensy 4.1

Teensy 4.1, the latest version of an astonishingly popular development platform featuring a 600 MHz ARM Cortex-M7 processor, an NXP iMXRT1062 chip, four times the flash memory of 4.0, and two new locations for adding even more memory optionally. Teensy 4.1 has the same size and shape as Teensy 3.6 (2.4 inches x 0.7 inches) and provides more I/O capabilities, including an ethernet PHY, SD card socket, and USB host port.

Operating at 600 MHz, Teensy 4.1 consumes approximately 100mA of current and provides support for dynamic clock scaling. Unlike traditional microcontrollers, where changing the clock speed can lead to incorrect baud rates and other issues, the hardware of Teensy 4.1 and the software support for Arduino timing functions in Teensyduino are designed to allow for dynamic speed changes. Serial baud rates, audio streaming sample rates, and Arduino functions like delay( Show More
