Per special request, Auvidea can manufacture the board with CAM1_PWDN and CAM2_PWDN with pull up 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).
This modification should be performed with care and some good soldering skills.
Auvidea does not cover damages inflicted by poorly performed modifications.
Please contact Auvidea for custom configurations.
