  1. Switch between 3.5 Teensy and power supply?

    Simple question, any reason I cannot put a motion senor switch directly on the 3.5 Teensy which is powered directly to a 5V switching power supply? My setup right now has a 5V power supply with an...

    Thank you for the input. Really helpful and right to the point. Teensy is probably more reliable than the SD card. I am using both since the the BMP does get loaded from the SD card. Great feedback....
