I'm trying to connect a camera module ( OV7670 ) to my nRF51822 EK. The camera requires an operating current of 18mA. If i were to connect the 3.3V rail input for the camera to the VCC of the nRF51822 EK, would i be able to provide this much current? is there a limit to the current that i can supply via the VCC rail ( assuming i dont exceed supply regulator capacity? )
