Parts

Required

Soldering

Diodes

Orientation: Black bar facing downwards or towards the footprint indicator.

1. Solder one pad.
2. While holding diode with tweezers, reflow solder and place diode down on pad.
3. Solder other pad.

• Note, when working with MELF package diodes, you may need to reflow and add more solder a couple times before an adequate connection is made.

Hotswap sockets

1. Solder one pad.
2. While holding hotswap socket (fingers are fine), reflow solder and place socket down on pad.
3. Solder other pad.

• Note, don't hesitate to use a little extra solder, as that will help secure the socket and prevent it from being ripped off.

Microcontrollers

Orientation: Both microcontrollers CONTROLLERPLACEMENT.

• Note, it is recommended to flash each microcontroller prior to soldering. See firmware section for more.

1. Insert headers from front, solder in from the back.
2. Place microcontroller CONTROLLERPLACEMENT.
3. Apply solder to all pins.
4. Use flush cutters or similar to trim excess from pins on each side.

Misc.

Reset switches

1. Solder one pad.
2. While holding switch with tweezers, reflow solder and place switch down on pad.
3. Solder remaining pads.
