    Bare bone teensy 3.2, using teensy on bare bone PCB

    I have burned blinking LED program into teensy 3.2. Then I removed micro-controller from teensy3.2 and put that in a separate PCB custom PCB with the required circuitry. But LED is not blinking in the new environment. Do we need some more circuitry as to turn ON the micro-controller.

    Running teensy main micro-controller this way is bad. Any help will be appreciated.

    You need 3.3V power on VBAT.
