Description
The DEV-20359 is Teensy 4.1 without Ethernet Development Board integrates an ARM Cortex-M7 processor at 600MHz, with a NXP iMXRT1062 chip. The Teensy 4.1 is the same size and shape as the Teensy 3.6 (2.4in by 0.7in), and provides greater I/O capability, including an SD card socket, and USB host port.
Teensy 4.1 hardware and Teensyduino's software support for Arduino timing functions are designed to allow dynamically speed changes. Serial baud rates, audio streaming sample rates, and Arduino functions like delay() and millis(), and Teensyduino's extensions like IntervalTimer and elapsedMillis, continue to work properly while the CPU changes speed.
