This is the Adafruit\u003cstrong\u003e 0.54\" 4-Digit 14-Segment Display FeatherWing\u003c\/strong\u003e! This 14-segment FeatherWing backpack makes it really easy to add a bright alphanumeric display that shows letters and numbers in a beautiful hue. It's super bright and designed for viewing from distances up to \u003cstrong\u003e23 feet\u003c\/strong\u003e (7 meters) away.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWorks with any and all Feathers!\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e14-Segment Matrices\u003c\/strong\u003e like these are 'multiplexed' - so to control all the fourteen-segment LEDs you need \u003cstrong\u003e18 pins\u003c\/strong\u003e. That's a lot of pins, and there are driver chips like the\u003cstrong\u003e MAX7219\u003c\/strong\u003e that can control a matrix for you but there's a lot of wiring to set up, and they take up a ton of space. Wouldn't it be awesome if you could control a matrix without tons of wiring? That's where these Alphanumeric LED Matrix FeatherWings come in, they make it really easy to add a 4-digit alphanumeric display with decimal points.\u003c\/p\u003e\n\u003cp\u003eThe LEDs themselves do not connect to the Feather. Instead, a matrix driver chip (\u003cstrong\u003eHT16K33\u003c\/strong\u003e) does the multiplexing for you. The Feather simply sends \u003cstrong\u003eI2C commands\u003c\/strong\u003e to the chip to tell it what LEDs to light up and it is handled for you. This takes a lot of the work and pin-requirements off the Feather. Since it uses only I2C for control, it \u003cstrong\u003eworks with any Feather\u003c\/strong\u003e and can share the I2C pins for other sensors or displays.\u003c\/p\u003e\n\u003cp\u003eThis product kit comes with:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA fully tested and assembled Adafruit 4-Digit 14-Segment Alphanumeric Display FeatherWing\u003c\/li\u003e\n\u003cli\u003eTwo sixteen pin headers\u003c\/li\u003e\n\u003cli\u003eA bit of soldering is required to attach the matrix onto the FeatherWing but its very easy to do and only takes about 5 minutes!  \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e Feather board and 14-segment display are not included.\u003c\/p\u003e\n\u003cp\u003eOf course, in classic Adafruit fashion, there is a detailed tutorial showing you how to solder, wire and control the display. There's even a very nice library for the backpacks in both Arduino \u0026amp; CircuitPython so you can get running in under half an hour, displaying letters or numbers on the 14-segment. If you've been eyeing matrix displays but hesitated because of the complexity, this is the solution you've been looking for.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/itpIPCyUgS0?si=y9TVKpl30StFV_9m\u0026amp;start=257\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e0.54\" 4-digit 14-segment alphanumeric display\u003c\/li\u003e\n\u003cli\u003eDisplays numbers 0-9 and full alphabet (A-Z)\u003c\/li\u003e\n\u003cli\u003eSuper bright LED with 23 feet (7 metres) viewing distance\u003c\/li\u003e\n\u003cli\u003eWorks with any Feather board\u003c\/li\u003e\n\u003cli\u003eHT16K33 matrix driver chip for easy control\u003c\/li\u003e\n\u003cli\u003eI2C communication - requires only 2 pins\u003c\/li\u003e\n\u003cli\u003eShare I2C pins with other sensors or displays\u003c\/li\u003e\n\u003cli\u003eIncludes two sixteen-pin headers\u003c\/li\u003e\n\u003cli\u003eSoldering required (approximately 5 minutes)\u003c\/li\u003e\n\u003cli\u003eCompatible with Arduino and CircuitPython libraries\u003c\/li\u003e\n\u003cli\u003eFeather board and 14-segment display sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDimensions: 51mm x 23mm x 4.2mm\u003c\/li\u003e\n\u003cli\u003eWeight (just the Wing): 4.8g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eRevision History\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAs of \u003cstrong\u003eJanuary 10, 2022\u003c\/strong\u003e we've updated this PCB to have a Stemma QT connector on the I2C lines for attaching accessories to the Feather.
