cgo3 4k camera short-circuit

[Seong Yong Kim]

hi~ all.
I made a mistake while soldering for top-board of cgo3.
finally top-board smoked and broken.



And then all disassembled.



I want to test whether the camera module and WiFi module is normal.
Please tell me what is + or gnd line for connector.
Do you work in a few volts ?



Thanks.
