what is the VIL, VIH, VOL, VOH  thresholds for USB-TO-GPIO2 adaptor.

Vin Low (max) is 0.8V

Vin High (min) is 1.35V

Vout Low (max) at 20mA is 0.4V 

Vout High depends on the external pull-up, but leakage when the internal pull-up it 3.3V is "OPEN" is less than 10μA 

Andreas Jonsson said:

can it support 1.8V logic ?

Yes, it can support 1.8V external pull-up.

Great, thanks Peter
