Is voltage on SCCB/YUV SCL SDA 1.8V?

If I connect other devices to the SCCB pins on the DVP connector, what should the voltage be? 1.8V?

DVP pins are on power bank 6&7 and you can set 1.8V or 3.3V in sofware.

Ok great. Wouldn’t there be a default setting, or does MaixPy not use this? Should that have any impact on compatible cameras? It seems that the OV line supports 1.7V - 3.3V
