- All Teensy boards are factory tested and loaded with a simple BLINK sketch before packaged
- As shipped this sketch is not USB Serial active and will not present as such on connecting to PC
- The first programming of a Teensy board takes a Button Press
- The Button on the Teensy is to enter Program mode, it is not a Reset button
- Pressing the Button puts the Teensy into a HID mode to present a link to program the Teensy
