Hi,
I just installed an Arduino Mega Sensor Shield on my Due. The problem is that all of the VCC connections on the sensor are 5 volts. I am glad I did not plug in any sensors yet!!!
This is not compatible with the 3.3 sensors which I will use with Due or the I/O of the sensors.
Is there a connection on the board I can change to route the 3.3 volt supply to the pins?
Can you share a schematic?
Many Thanks,
Joe

Sorry, we don't have schematics.
You can get 3.3V power from this pin:

Re: Due and Sensor Shield Problems. I need help
I have the V4 version of the sensor shield.
I want to disconnect 5v from UART, I2C etc.
How would I do that?
The company that sold me the cards said they would work with Due, but that is clearly a problem since the shield brings 5V to the connectors instead of 3.3V

Sorry, I can not see the picture.
Here is the PCB schematics of Mega V4. You can disconnect 5V power, and connect it 3.3V pins, then all the VCC will be 3.3V
