Property says VCC, description says VDD, datasheet says 5V (not 3.3V).

I guess this should be for the 5V case, no? If that's true, then I think
that 5V pin is not a controllable supply ever, because this product is
purely for RPi which has 5V pins directly tied to main power supply.


Best regards,
Krzysztof
