Power Requirements

For PC Work:

Please either use a 2 Amp 5v power supply, or externally power the unit through the ESC breakout. Most computers only provide upto 500ma and the board needs roughly 700mA to boot, before stabilising between 300mA and 400mA with 1 camera attached.

For Deployment:

The board contains a 5v, 3 Amp BEC suitable for input between 5.5v to 36v. This powers the CM4, the USB ports, pin headers and the onboard 3.3v LDO regulator.

The 3.3v LDO regulator is normally activated once the CM4 has started to boot. If no CM4 is connected the DIP Switch (2) must be ON to activate. This powers the STM32 and the pin header.
