this Module is activated via the SmartGeocache Homepage. With it you can switch more Power ( higher Voltages and Amps )

e.g. you can connect POWER LEDS and switch them on and off in your TB-Hotel

You can connect up to 5 of these Modules to the SmartGeocache V5.0 Mega

Pin 3&4 of the Mega do toggle during boot (start procedure) for about half a second so the Relay may "flicker" duing this time.

The Vcc Pin of the Relay Extension supplys 5V and the GND Pin  supplys 0V. You can use those to supply your Circuit together with the switching contact of the Extension.

Possible Connections:

SmartGeocache V5.0 Mega  :  Pin 1, 3, 4, 5, 6
SmartGeocache V5.0 Mini : Pin 1
