3 Basic Camera Operation
The STV0674 Flash Board has three buttons and 2 LEDs to provide the User Interface. LED1 is
the upper bi-colour LED. LED2 is the red LED below. The SHUTTER button is on the top of the
PCB, the MODE button is on the side and the Power On button on the front close to the
USB\Power connection.
Operation is described as “ untethered ” (stand-alone) when the board is not plugged into USB and
operation is controlled via the on board UI only or “ tethered ” when the board is connected to a PC
via USB and uses the power supplied by USB. Untethered operation requires a “AAA” battery on a
separate PCB to provide power which is connected to the main PCB via the USB connector.
