Description
Teensy 4.0 consumes approximately 100mA current, when running at 600 MHz! It also provides support for dynamic clock scaling. Teensy 4.0 now provides a power shut off feature. This can be done by connecting a pushbutton to the On/Off pin, now the 3.3V power supply can be completely disabled by holding the button for 5 seconds, and turned back on by a button press. If a coin cell is connected to VBAT, Teensy 4.0's RTC also continues to keep track of date & time while the power is off. Teensy 4.0 also can also be overclocked, well beyond 600MHz!
Note: Please be aware that the Teensy 4.0 does not include headers and will need to be purchased separately and soldered on yourself.
