Serial header gets 3.3 V out - Bluetooth HC-06 needs at least 3.6 V ?

[RK_aus_S]

Hi

I just got my CurrentRanger and I wonder if the device supplies enough voltage on the serial header to operate the HC-06 Bluetooth device?
May be a silly question, but I measure only 3,3 Volts on the serial header, but it seems the HC-06 needs at least 3,6 V, doesn't it?

Regards

It's fine with 3.3V.
