The module uses the Raspberry Pi's I2C interface and requires only two signal lines, leaving the remaining GPIO pins available. This creates room for additional expansions on the same bus.\u003c\/p\u003e \u003cp\u003eThe 16 digital outputs and inputs are connected to the Raspberry Pi via the 40-pin header and draw their power directly from the main board. Each module receives its own I2C address and can therefore be controlled individually. Up to four of these boards can be operated in parallel without requiring resistors, jumpers, or soldering.\u003c\/p\u003e \u003cp\u003eThe board is suitable for applications with multiple sensors and relays, such as controlling pumps, fans, and switching actuators in greenhouses or monitoring multiple pressure switches in machine prototypes. It can also be used for lighting control systems with many inputs and outputs when the Raspberry Pi's native GPIO pins are insufficient.\u003c\/p\u003e \u003cp\u003eOperation requires a Raspberry Pi 2, 3, or newer single-board computer. I2C addressing must be configured in the control software. A maximum of 25 milliamps can be switched at each output; external drivers or relays must be connected upstream for higher loads.\u003c\/p\u003e \u003ch3\u003eSafety information\u003c\/h3\u003e \u003cp\u003eThe module is not intended for installation in household electrical circuits and is exclusively intended for building prototypes and for testing and development purposes. Observe the maximum current draw per output. When working on or near electrical installations, consult a qualified electrician.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x GPIO expansion board for Raspberry Pi 2, Pi 3, Model B\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":66044737782109,"sku":"F23108695","price":8.91,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/gpio-erweiterungsboard-fuer-raspberry-pi-2-pi-3-model-b-funduino-3103667.png?v=1791488633","url":"https:\/\/funduino.com\/en\/products\/gpio-expansion-board-for-raspberry-pi-2-pi-3-model-b","provider":"Funduino","version":"1.0","type":"link"}
