If at a later date you require the ID pins to be reconnected this can be done by bridging the jumper with solder.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: The Giant Butterfly uses a 4-layer PCB to achieve its small footprint. Due to the traces crossing over each other we do not recommend using it where high-frequency signals\/switching is required. \u003cstrong\u003eRaspberry Pi, headers and HATs not included.\u003c\/strong\u003e\u003c\/p\u003e \u003ch2\u003eBefore Using\u003c\/h2\u003e \u003cp\u003eWhen using multiple HATs you MUST check for conflicts - for example, enable\/select pins when using SPI, I2C addresses and GPIO pin conflicts and modes, 8086 advise checking on pinout.xyz and\/or with the HAT manufacturer for used pins\/modes in use.\u003c\/p\u003e \u003ch2\u003eAssembly \/ Soldering\u003c\/h2\u003e \u003cp\u003eThe Giant Butterfly board would normally be used with 3x male + 1x tall stacking headers (not included). The tall stacking header is for the Raspberry Pi and the primary HAT, and the male headers is for the other HAT positions.\u003c\/p\u003e \u003cul\u003e \u003cli\u003eThe top side of the board has the \"Giant Butterfly\" text and the underside has the ID solder jumpers.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSee the important notes below for the primary HAT position\u003c\/strong\u003e. Push the female header with long pins through from the bottom and solder into the holes closest to the HAT position marked \"RPi\".\u003c\/li\u003e \u003cli\u003eNext the 3 male headers can be soldered into the other 3 positions.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eImportant Notes\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eWhen soldering the long female header onto the Giant Butterfly please be aware of the clearance with the USB\/Ethernet connectors on the Raspberry Pi. Use a tall header with shrouds like this one.\u003c\/li\u003e \u003cli\u003eEither way, 8086 strongly recommend applying a couple of layers of electrical insulation tape onto the top of the connector (USB[Pi4]\/Ethernet) under the Giant Butterfly board to prevent shorts.\u003c\/li\u003e \u003cli\u003ePin 1 of each HAT position is marked with a white line next to the square pad.\u003c\/li\u003e \u003c\/ul\u003e","brand":"8086","offers":[{"title":"Default Title","offer_id":48624140288218,"sku":"cxb1789684393193","price":3.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/giant-butterfly-for-raspberry-pi_1.jpg?v=1789684399","url":"https:\/\/memoryfoamwear.shop\/products\/giant-butterfly-for-raspberry-pi","provider":"My Store","version":"1.0","type":"link"}
