This board is fully assembled and comes with 3 x 40 Pin headers, so you'll have up to 4 x 40 Pin GPIO arrays to add \"stuff\" to your Raspberry Pi.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe product comes fully assembled with our push-fit \"plug \u0026amp; play\" Single Shroud Header, Socket Header, and 14mm HAT Mounting Kit\u003cstrong\u003e,\u003c\/strong\u003e so there's no soldering required.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eModMyPi Triple GPIO Expansion Board\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eTriple 40 Pin GPIO Header Multiplexor\u003c\/li\u003e\n\t\u003cli\u003eHAT Compliant Layout\u003c\/li\u003e\n\t\u003cli\u003eUses SMT Socket Header \u0026amp; 40 Pin Extra Tall \"Single Shroud\" Header\n\u003c\/li\u003e\n\t\u003cli\u003eIncludes 14mm Mounting Kit\n\u003c\/li\u003e\n\t\u003cli\u003eFully Assembled - No Soldering Required\u003c\/li\u003e\n\t\u003cli\u003eStackable\u003c\/li\u003e\n\t\u003cli\u003eFully Labelled GPIO Silkscreen\u003c\/li\u003e\n\t\u003cli\u003e3 x 40 Pin Breakout Array (2 x 20) with pre-soldered Raspberry Pi header's\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"ModMyPi","offers":[{"title":"Default Title","offer_id":53751174300011,"sku":"wtd1787257875138","price":5.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/1268\/3883\/files\/modmypi-triple-gpio-expansion-board-discontinued_1.jpg?v=1787257883"},{"product_id":"modmypi-raspberry-pi-prototyping-hat-discontinued","title":"ModMyPi Raspberry Pi Prototyping HAT [Discontinued]","description":"\u003cp\u003eDesign your own Raspberry Pi HAT, attach custom circuits, LEDs, IC's, potentiometers and more, with our Raspberry Pi Prototyping HAT!\u003c\/p\u003e\n\u003cp\u003eThe HAT consists of a 0.1\" prototyping soldering grid for attaching your peripherals with breadboard style traces for easy links between components.\u003c\/p\u003e\n\u003cp\u003eThe prototyping board includes 3.3V, 5V \u0026amp; GND strips for easy power connections and a labelled GPIO breakout array (2 x 20) which fits a Raspberry Pi header (not included) for quick GPIO links! \u003c\/p\u003e\n\u003cdiv\u003e\u003cstrong\u003eThe product comes fully assembled with our push-fit \"plug \u0026amp; play\" Double Shroud Header, Socket Header, and 14mm HAT Mounting Kit\u003cstrong\u003e,\u003c\/strong\u003e so there's no soldering required.\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHAT Compliant Layout\u003c\/li\u003e\n\u003cli\u003ePower Strips: 3.3V, 5V \u0026amp; GND\u003c\/li\u003e\n\u003cli\u003e0.1\" Prototyping Soldering Grid\u003c\/li\u003e\n\u003cli\u003eUses SMT Socket Header \u0026amp; 40 Pin Extra Tall \"Double Shroud\" Header \n\u003c\/li\u003e\n\u003cli\u003eIncludes 14mm Mounting Kit\n\u003c\/li\u003e\n\u003cli\u003eFully Assembled - No Soldering Required\u003c\/li\u003e\n\u003cli\u003eStackable\u003c\/li\u003e\n\u003cli\u003e40 Pin Breakout Array (2 x 20) fits a Raspberry Pi header (Not Included)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ModMyPi","offers":[{"title":"Default Title","offer_id":53751174365547,"sku":"akl1787257876114","price":5.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/1268\/3883\/files\/modmypi-raspberry-pi-prototyping-hat-discontinued_1.jpg?v=1787257884"},{"product_id":"raspberry-pi-gpio-breadboard-breakout-pro-discontinued","title":"Raspberry Pi GPIO Breadboard Breakout PRO [Discontinued]","description":"\u003cp\u003eReady to get \u003cstrong\u003ePRO\u003c\/strong\u003e with your Raspberry Pi breakout boards?
