![]() Teensy 4.0 also provides a power shut off feature. 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. ![]() Unlike traditional microcontrollers, where changing the clock speed causes wrong baud rates and other issues, Teensy 4.0 hardware and Teensyduino's software support for Arduino timing functions are designed to allow dynamically speed changes. To help reduce power, Teensy 4.0 provides support for dynamic clock scaling. When running at 600 MHz, Teensy 4.0 consumes approximately 100 mA current, considerably more than most microcontrollers. ![]() Teensy 4.0 can be programmed using the Arduino IDE with Teensyduino add-on. ![]() It even has a graphics processor! All this for two sawbucks. ![]() It's perfect for when you need tons of flash, RAM and, to crunch lots of data, or when you need two full speed USB ports. Who else could pack a 600 MHz microcontroller into such a Teensy little board? The Teensy 4.0 features an ARM Cortex-M7 processor at 600 MHz, with a NXP iMXRT1062 chip, the fastest microcontroller available today - ten times faster than the Teensy 3.2! The NXP iMXRT1062 is a 'cross-over' processor, which has the functionality of a microcontroller, at the speeds of a microcomputer. ![]()
