Per special request Auvidea can manufacture the board with CAM1_PWDN and CAM2_PWDN with
pullup to 1.8V.
CSI default voltage is 3.3V but it can be changed to 5V. To perform this modification, you need to
move the bead from the 3.3V location (marked with the number 3 as shown in the picture) to the 5V
location (marked with the number 5 as shown in the picture).
The same process applies to I2C where you must move two beads to the desired location of 1.8
(1.8V) or 3.3 (3.3V).
