The interface is ready for soldering. All the extra features come in the MAX II board, as peggyback board. See the hole range of MAX II connectors. This CPLD MAX II board is my Standard hardware unit.
The interface board has 71x160mm and is mounted inside the frame. A few extra external flatcables are needed for the external modules like the LCD display, the IR controller into the optical lens and the highpower drive for the external shutter unit. All batteries are also external so they can rapid exchange for loading. The external flashes ( max 3 x SB80/SB800) are all driven into TTL mode so I can adjust the flashpower into the field by turning on one power button on the frame.
