Hi,
I bought a Teeny 4.0 back on 8/15/2019 and finally have gotten around to pulling it out of the bag and plugging it in.
I have tried 2 known good USB cables. With each I measure 5.0V on the the Vin pin but 0.185V on the 3.3V pin.
I have not soldered headers on it or done anything with it. There are no LEDs lit or blinking.

Does anyone know what could be wrong?
Thanks,
Bill
