# Adafruit LED Backpacks

## Assembly and Arduino Wiring

For the STEMMA QT version, you can solder the headers on, or you can simply use a STEMMA QT cable!

- **Backpack + (VCC)** to **microcontroller 5V** (if using a board with 5V logic, otherwise use 3V for boards with 3V logic) **(red wire)**
- **Backpack - (GND)** to **microcontroller GND (black wire)**
- **Backpack D (SDA)** to **microcontroller SDA (blue wire)**
- **Backpack C (SCL)** to **microcontroller SCL (yellow wire)**

To assemble the LED backpack, follow along below.

Info: 

When you buy a pack from Adafruit, it comes with the fully tested and assembled backpack as well as a 7-segment display in one of the colors we provide (say, red, yellow, blue or green). You'll need to solder the matrix onto the backpack but it's an easy task.

![led_matrix_7segparts.jpg](https://cdn-learn.adafruit.com/assets/assets/000/000/149/medium640/led_matrix_7segparts.jpg?1396760793)

Remove the parts from packaging and place the LED matrix OVER the silkscreen side.&nbsp; **DO NOT PUT THE DISPLAY ON UPSIDE DOWN OR IT WONT WORK!! Check the image below to make sure the 'decimal point' dots are on the bottom, matching the silkscreen.** ![led_matrix_7segplacetop.jpg](https://cdn-learn.adafruit.com/assets/assets/000/000/150/medium640/led_matrix_7segplacetop.jpg?1396760798)

Turn the backpack over so it is sitting flat on the matrix.

![led_matrix_7segside.jpg](https://cdn-learn.adafruit.com/assets/assets/000/000/151/medium640/led_matrix_7segside.jpg?1396760809)

Solder all 14 pins.![led_matrix_7segsolder.jpg](https://cdn-learn.adafruit.com/assets/assets/000/000/152/medium640/led_matrix_7segsolder.jpg?1396760814)

Clip the long pins.![led_matrix_7segclip.jpg](https://cdn-learn.adafruit.com/assets/assets/000/000/153/medium640/led_matrix_7segclip.jpg?1396760824)

Now you're ready to wire it up to a microcontroller. We'll assume you want to use a 4pin header. You can also of course solder wires directly. Place a 4-pin piece of header with the LONG pins down into the breadboard.![led_matrix_place4pin.jpg](https://cdn-learn.adafruit.com/assets/assets/000/000/155/medium640/led_matrix_place4pin.jpg?1396760834)

Place the soldered backpack on top of the header and Solder 'em!![led_matrix_7segheader.jpg](https://cdn-learn.adafruit.com/assets/assets/000/000/156/medium640/led_matrix_7segheader.jpg?1396760843)

That's it! now you're ready to run the firmware!- [Previous Page](https://learn.adafruit.com/adafruit-led-backpack/0-dot-56-seven-segment-backpack.md)
