Need to check what supply voltage OpenMV needs. Thought it was 3.3V but might not be. Also need to check STM32 supply voltage
STM32 takes 3.3 V as expected. The OpenMV expects 3.6-5V as a raw input and regulates it to 3.3V. Testing has shown the board successfully outputs 3.3V to VCC. The board is also missing two resistor arrays (10K) because we didn't have the parts. These connect the SD card to VCC hence, the SD card won't work without them. Otherwise the board should function as expected
Discovered that one of the missing resistor arrays RN3 is used by the MCU Boot0 and NRST Pins as well as the SD card. So the board likely won't work without it.
Per https://github.com/spacecraft-design-lab-2019/documentation/issues/12#issuecomment-554794443, the STM32 from OpenMV-H7 and OV7725 from OpenMV3 have been installed on the camerav00 board. I also moved over the necessary resistor arrays and the RGB indicator LED for debugging purposes.
