The Teensy 4.1 - without internet is a small development board armed with a 32 bit 600 MHz ARM Cortex-M7 processor. This version has the same processor as the Teensy 4, but with a lot more I / O! This version has more Flash memory, a micro SD card connection and more available IO pins. The Teensy development boards can even be programmed with Arduino code by downloading the TeensyDuino addon for the Arduino IDE.
The Teensy 4.x supports dynamic clock scaling. Unlike traditional microcontrollers, where changing the clock speed causes incorrect baud rates and other issues, the Teensy 4.0 hardware and Teensyduino's software support for Arduino timing functions are designed to allow for dynamic speed changes. Serial baud rates, audio streaming sample rates, and Arduino features like delay () and millis (), and Teensyduino's extensions like IntervalTimer and elapsedMillis will continue to work properly as the CPU changes speed.
The Teensy 4.x also offers a power shut-off feature. By connecting a push button to the on / off pin, the 3.3V power can be completely turned off by pressing and holding the button for 5 seconds and turned back on by briefly pressing the button. When a button cell is connected to VBAT, Teensy 4.0's RTC also keeps date and time while the power is turned off.
The Teensy 4.x can also be overclocked, well beyond 600 MHz!
