Adafruit 0.56″ 4-Digit 7-Segment Display w/I2C Backpack – White – What’s better than a single LED? Lots of LEDs! A fun way to make a small display is to use an 8×8 matrix or a 4-digit 7-segment display. 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 in two flavors – a mini 8×8 and a 4-digit 0.56″ 7-segment. They work perfectly with the matrices we stock in the Adafruit shop and make adding a bright little display trivial.

Adafruit Pi Box – Enclosure for Raspberry Pi Computers – Keep your Raspberry Pi® computer safe and sound in this lovely clear acrylic enclosure. We designed this case to be beautiful, easy to assemble and perfect for any use (but especially for those who want to tinker!)

The case comes as 6 pieces that snap together, made of crystal-clear acrylic. This ingenious design has no screws or standoffs and there are cute little feet cut into the sides so that it stands up above your desk. There are engraved labels on all the connector slots. You can use all of the connectors on the edges of the Pi: HDMI, Audio, Video, SD slot, micro USB power, Ethernet and the two USB ports. We also added a slot so that you can connect a 26-pin IDC cable to the GPIO breakout pins on the Pi and pass it though the case. For more advanced hacking, the enclosure is designed so that you can remove the top piece and plug any sort of cables you wish into the breakouts in the middle. The case is airy enough that no additional vents or cooling is required – we tested the enclosed Pi over a 24 hour period at full load with no significant increase in temperature.
