Description
A quartz crystal based SMD clock modul, with selectable freq outputs.
The freq range is from 16 to /4 Hz. There is a pinout, where power could be supplied to or drawn from the board. The power limitations were not tested, but definitely not for anything high demand. The topmost pin would carry the selected clock signal from one bord to the other. If pins are not an option, solderpads that are connected to them, could provide the connection.
