The screw terminals enable easy connection of sensors, actuators, and power supplies without plug connections. This eliminates the need to build wiring on a breadboard or use individual components.\u003c\/p\u003e \u003cp\u003eThe module uses the microcontroller's available GPIO pins and makes them accessible via standardized connection blocks. The digital outputs control relays, motors, or lights. Analog inputs record measurement values from sensors such as temperature, light, or humidity sensors. The integrated RTC module provides timestamps and enables time-based processes even without an external power supply, as it has a battery holder.\u003c\/p\u003e \u003cp\u003eTypical applications include home automation with time-controlled switches, data logging of sensor readings over longer periods, or maintenance tasks in prototype systems. Setting up simple alarm functions is also significantly accelerated by the preassembled circuitry.\u003c\/p\u003e \u003cp\u003eAn Arduino UNO or MEGA board is required. The shield is plugged onto the pin headers and requires no additional power supply when the host board is powered. For battery-backed timekeeping, a button cell (usually CR2032) must be inserted.\u003c\/p\u003e \u003ch3\u003eSafety Notice\u003c\/h3\u003e \u003cp\u003eThe module is not intended for integration into the household electrical circuit. It is intended exclusively for building prototypes and for testing and development purposes. When controlling devices connected to the electrical installation, all work must be carried out by a qualified electrician.\u003c\/p\u003e \u003ch4\u003eScope of Delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x\u0026nbsp;Multi function Shield UNO\/MEGA\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":65998293107037,"sku":"F23106843","price":3.56,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/multifunktions-shield-unomega-funduino-1127323.png?v=1791495478","url":"https:\/\/funduino.com\/en\/products\/multifunction-shield-uno-mega","provider":"Funduino","version":"1.0","type":"link"}
