Here you can find all Extensions that can be connected to the SmartGeocache 5.0 Mini
Output Extensions can be activated by the Geocacher via the WiFi Homepage, like LEDs Laser or Motors.
The SGC 5.0 MEGA can also handle Input Extensions (Sensors), which the SGC 5.0 Mini can't do. Input Extensions are Sensors which can be triggered by the Geocacher, e.g. a specific Webpage on the SmartGeocache WiFi Homepage can only be opened, if the Sensor is triggered by the Geocacher
