Solder all 16 pins. Apply the soldering iron to the pin and hold it there for a few seconds. Add small amount of solder to heated pin, not the tip of the iron! Clip and trim the pins when you're finished soldering.
Wiring 8x8 LED MatrixApply a small amount of solder to tin the 4 pins on the top of the 8x8 LED matrix backpack. Try to heat the back of the pin, and then applying the solder to the front of the pin.
Solder 4 strips of 30 gauge wrapping wire to the 4 pins on the backpack. Try heating the back and pushing the wire through once it's liquidy.
Connecting 8x8 LED Matrix to GEMMAUse a third helping hand to hold your components in place while you solder. Tin the 6 pins on the GEMMA. Solder the 4 wires from the LED Matrix to the pins of the GEMMA. Below is a mini reference list for each pin.
Tin the middle and any outside pin of the slide switch with a small amount of solder. Be sure to apply rosin to each pin in order for the solder to stick properly. Use heat shrink tubing to secure our soldered connections.
Snip off the extra pin in the switch. It could cause a short in our circuit once it's mounted in the box enclosure.
|Use a third helping hand to assist you. Use each arm to hold onto the JST ports. Use diagonal tweezers to hold the stripped wire with one hand while using your other hand to hold the soldering iron.|
