Soldering Instructions - V2

Version from 2023

How to Proceed

• Always solder only one level at a time.
• Take one component from the holder, solder it, and only after that take another one. (They are easy to mixup.)
• Once you have soldered everything, glue a padding underneath the USB connector.

Important Information

• Start by soldering the integrated circuit. As last solder the LED.
  • Be mindful of the orientation of the integrated circuit. If you're unsure, ask the instructor.
• Polarity usually matters with LEDs. However, on this board, you don't have to worry about polarity; the circuit is designed to be polarity-agnostic.

Work Safety

• The tip of the soldering iron is hot (~300 °C).
• Always place the soldering iron back in its stand.
• Keep your workspace tidy.
• If you get burned, go and cool the burned area with water (do not use ice). Don't rub anything on the burned area.
