Teensy 4.0
pjrc_teensy_4_0
600 MHz Demon.
A 600 MHz Cortex-M7 on a stamp-sized board: so much raw power it will be bored in most of your projects.
Good to know
- 3.3V only, not 5V tolerant – use level shifters for 5V sensors.
- Uploading: button + Teensy Loader; the IDE needs the Teensyduino add-on.
- For external power, cut the VUSB–VIN bridge on the underside.
- Extra signals are available on the bottom pads.
