It plugs in and draws power directly from the microcontroller board, so no separate power supply is required.\u003c\/p\u003e \u003cp\u003eThe matrix of digital and analog connections makes it possible to build more complex circuits without multiplexing logic. The perfboard layout with continuous power distribution rails saves wiring work during prototyping. No calibration or configuration is required.\u003c\/p\u003e \u003cp\u003eTypical applications include sensing multiple parameters at once, such as environmental monitoring with temperature, humidity, and light sensors. It also makes control tasks with many outputs practical, such as switching multiple devices or reading switch matrices. In everyday prototyping, the board saves time on pin management and enables faster iterations.\u003c\/p\u003e \u003cp\u003eThe board can only be used with microcontroller boards that provide the matching connector. A slot must be available on the host, and the host board logic and operating voltage (typically 3.3 or 5 V) are already provided.\u003c\/p\u003e \u003ch3\u003eSafety Notice\u003c\/h3\u003e \u003cp\u003eThis expansion board is intended exclusively for building prototypes and for testing and development purposes; it is not suitable for installation in household mains wiring. Qualified electricians must be consulted when working on or in the immediate vicinity of electrical installations. If you have questions about commissioning, consult a qualified electrician.\u003c\/p\u003e \u003ch4\u003eScope of Delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x NANO R3 I\/O Expansion Board - expansion board\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":65998292451677,"sku":"F23107461","price":2.43,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/nano-r3-io-expansion-prototyping-board-v30-erweiterungsplatine-funduino-9731505.png?v=1791496418","url":"https:\/\/funduino.com\/en\/products\/nano-r3-i-o-expansion-prototyping-board-v3-0-expansion-board","provider":"Funduino","version":"1.0","type":"link"}
