{"product_id":"0802-lcd-i2c-adapter-16502","title":"0802 LCD I2C Adapter","description":"\u003cp\u003eThis is a circuit board which acts as an adapter between the common I2C backpacks and the 0802 format display, providing a compact and tidy result. It works with the 14-pin and 16-pin display types.\u003c\/p\u003e\n\u003cp\u003eThe I2C backpack is not included. Search \"I2C Display adapter\" and look for the ones in the second picture.\u003c\/p\u003e\n\u003cp\u003eThe green LCD options have no backlight\u003c\/p\u003e\n\u003cp\u003e#### Instructions\u003c\/p\u003e\n\u003cp\u003e- Place the display face down.\u003cbr\u003e\n- Insert 2 x 7 header pins into positions 1-14, short end first. DO NOT SOLDER. On 16 pin displays, leave 15 \u0026amp; 16 open (they are the same as A and K).\u003cbr\u003e\n- Insert 2 single header pins into position A and K, short end first. DO NOT SOLDER.\u003cbr\u003e\n- Place the adapter board on the pins. Display pin 1 to board pin 1.\u003cbr\u003e\n- There are two positions for A and K - move the single pins around for the best fit with your display - there appears to be no standard locations for these on the displays. The single pins have a bit of wiggle, so it's ok to lean them a bit if needed.\u003cbr\u003e\n- Solder the headers to the adapter board. DO NOT SOLDER TO THE DISPLAY.\u003cbr\u003e\n- Lift the adapter board off the display.\u003cbr\u003e\n- Trim off the long ends of the header pins with wire cutters. Eye protection is advised - those things fly!\u003cbr\u003e\n- These instructions assume that the I2C adapter has the 16 pin header already installed. If not - you need that done before the next step.\u003cbr\u003e\n- Insert the I2C module into the adapter board - on the other side from where you had the display. The GND pin on the I2C module is closest to the 14-pin header. Look at the picture.\u003cbr\u003e\n- Solder 1 pin on the I2C module, then straighten it up. Then solder the other 15 pins.\u003cbr\u003e\n- Trim off the long ends of the header pins with wire cutters.\u003cbr\u003e\n- Position the display back on its headers.\u003cbr\u003e\n- Solder the 16 pins to the display.\u003c\/p\u003e\n\u003cp\u003eNotes:\u003c\/p\u003e\n\u003cp\u003e- Many of these I2C modules include a jumper to the backlight circuit. My preference is to solder a 330R resistor in that position as a current limiter, at least on 5V projects. probably not needed on 3.3V\u003cbr\u003e\n- These modules also include the contrast pot and address jumpers. Default address is 0x27.\u003cbr\u003e\n- I2C bus requires pullup resistors somewhere on the bus. 4.7K usually does the trick.\u003cbr\u003e\n- I use this library for these displays.https:\/\/github.com\/mathertel\/LiquidCrystal_PCF8574\u003c\/p\u003e","brand":"Red Hunter Store","offers":[{"title":"Board only","offer_id":43965884334140,"sku":"RHS-080LCDI2C-BOA-9PDS","price":1.25,"currency_code":"USD","in_stock":true},{"title":"Assembled Green LCD","offer_id":43965884366908,"sku":"RHS-080LCDI2C-ASS-9PDS","price":12.95,"currency_code":"USD","in_stock":true},{"title":"With loose blue LCD","offer_id":43965884399676,"sku":"RHS-080LCDI2C-WIT-9PDS","price":7.25,"currency_code":"USD","in_stock":true},{"title":"With loose green LCD","offer_id":43965884432444,"sku":"RHS-080LCDI2C-WIT-9PDS-2","price":8.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/1810\/3356\/files\/il_fullxfull.7721939117_k419.jpg?v=1770533871","url":"https:\/\/store.redhunter.com\/products\/0802-lcd-i2c-adapter-16502","provider":"Red Hunter Store","version":"1.0","type":"link"}
