Lots of LEDs! A fun way to make a numeric display is to use a 4-digit 7-segment display. LED matrices like these are 'multiplexed' - so to control all the seven-segment LEDs you need 14 pins. That's a lot of pins, and there are driver chips like the MAX7219 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. Here at Adafruit, we feel your pain! After all, wouldn't it be awesome if you could control a matrix without tons of wiring? That's where these adorable LED matrix backpacks come in.

They work perfectly with the displays we stock in the shop and make adding a bright display trivial.\u003c\/p\u003e\n\u003cp\u003eThe backpacks use a driver chip that does all the heavy lifting for you: They have a built-in clock so they multiplex the display. They use constant-current drivers for ultra-bright, consistent colour (the images above are photographed at the dimmest setting to avoid overloading our camera!), and 1\/16 step display dimming, all via a simple I2C interface. The backpacks come with address-selection jumpers so you can connect up to eight 7-segments (or a combination, such as four mini 8x8s and four 7-segments, etc) on a single I2C bus.\u003c\/p\u003e\n\u003cp\u003eSince this display has two LEDs per segment in series we need to power from 5V, even when using 3V logic.

You can drive these with less current to get the same brightness to save power, or crank them up to\u003cstrong\u003e 20mA\u003c\/strong\u003e and have them at their brightest.\u003c\/p\u003e\n\u003cp\u003eThese displays are multiplexed, common-cathode. What that means it that you can use a 74HC595 or just \u003cstrong\u003e8 microcontroller pins\u003c\/strong\u003e if you can spare them to control the 8 anodes (7-seg + decimal) at about \u003cstrong\u003e~15mA\u003c\/strong\u003e each, and then connect NPN transistors or a \u003cstrong\u003eTPIC6B595\u003c\/strong\u003e to the cathodes to sink the \u003cstrong\u003e8*20mA = ~120mA\u003c\/strong\u003e maximum per digit.\u003c\/p\u003e\n\u003cp\u003eWe strongly recommend getting our backpack version, which comes with an LED driver on the back.
