Besides the four 7-segments, there are decimal points on each digit and an extra wire for colon-dots in the center (good for time-based projects).\u003cbr\u003e\u003cbr\u003eYou can drive these with less current to get the same brightness to save power, or crank them up to 20mA and have them at their brightest.\u003cbr\u003e\u003cbr\u003eThese displays are multiplexed, common-cathode. What that means it that you can use a 74HC595 or just 8 microcontroller pins if you can spare them to control the 8 anodes (7-seg + decimal) at about ~15mA each, and then connect \u003ca href=\"\/en-eu\/products\/bipolar-transistor?variant=373573613\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eNPN transistors\u003c\/a\u003e or a TPIC6B595 to the cathodes to sink the 8*15mA = ~160mA maximum per digit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003ca href=\"\/en-eu\/products\/adafruit-0-56-4-digit-7-segment-display-w-i2c-backpack\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eWe strongly recommend getting the backpack version, which comes with an LED driver on the back.\u003c\/a\u003e This version is just the raw display, and requires a lot more work to get running!\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThis is a Common Cathode LED display\u003c\/li\u003e\n\u003cli\u003eDimensions: 0.76\" x 1.9\" (19.3mm x 50.3mm) Weight: 8.3g\u003c\/li\u003e\n\u003cli\u003eDatasheet:\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn-shop.adafruit.com\/datasheets\/865datasheet.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eRed\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn-shop.adafruit.com\/datasheets\/BL-Q56C-43.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eGreen\u003c\/a\u003e - This data sheet has an accurate pinout diagram but this is \u003cstrong\u003enot\u003c\/strong\u003e a Bet Lux model!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Red","offer_id":31551016861779,"sku":"ADA865","price":3.95,"currency_code":"EUR","in_stock":false},{"title":"Green","offer_id":31551016894547,"sku":"ADA813","price":3.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/865-00.jpg?v=1582104244","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/7-segment-clock-display-0-56-digit-height","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
