3.13.2 Supply Voltage
To support a variety of camera modules with different image sensors, the digital core voltage
(DVDD) and analog voltage (AVDD) can be configured
via the pin headers “1V2-1V8” and
“2V8-3V3”. The following chapters describe the voltage levels for each pin header respectively.

Do n
ot Leave “1V2-1V8” Open
Please note that the DVDD voltage will be 3.3
V if the pin header “1V2-1V8” is
left open. This can damage a connected camera module.
