Product Description

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. We have them for a variety of 8x8 and 7-segment displays. They work perfectly with the displays we stock in the Adafruit shop and make adding a bright display trivial.

The 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 color (the images above are photographed at the dimmest setting to avoid overloading our camera!), 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 8x8's and four 7-segments, etc) on a single I2C bus.

The product kit comes with:

A fully tested and assembled LED backpack
Ultra-bright 4-digit 1.2" yellow seven-segment display
5-pin header

A bit of soldering is required to attach the matrix onto the backpack but its very easy to do and only takes about 5 minutes.

TECHNICAL DETAILS

Measurements after you mount the screen:

1.2 vs 0.56 4 Digit 7 Segment Display I2C-Backpack

Im direkten Vergleich der beiden Backpacks fällt auf, dass das 0.56-Display Kommas ( z.B. bei Temperaturwerten ) darstellen kann. Die untere Punkte-Reihe hierfür fehlt gänzlich beim 1.2-Display.
Ausserdem ist das gegossene, weiße Kunststoffgehäuse bei der Version 1.2 in sich recht stark verformt - auf die Länge von 120mm ist es um ca. 3mm konkav durchhängend, Produktionsfehler.
Ansonsten sind beide Displays einfach zu bedienen und bieten eine klare und helle Darstellung.
