hello


Welcome to the hello badge.

Assembling the kit

Your hello badge comes as a kit. You will need a soldering iron and solder to assemble the kit. The PCB is designed for lead-free solder, although any solder will work.

Apply the following steps to assemble the kit:

  1. Ensure you have all the bits supplied: PCB, battery, display, lanyard, alignment jig.
  2. Remove the PCB from the packaging.
  3. Remove the display from the packaging.
  4. Place the display screen-down in the alignment jig.
  5. Place the PCB in the alignment jig, such that the pins of the display fit through the I2C holes, and the back of the PCB is visible. Ensure the PCB surface is flush with the alignment jig.
  6. Solder the four pins.
  7. Remove the battery from the packaging.
  8. Connect the battery.
  9. Determine the final position for the battery, such that the battery is relatively central and that the wire isn’t so loose that it will catch on anything.
  10. Remove the protective film from the double sided tape on the back of the PCB.
  11. Stick the battery down carefully into its final position.
  12. Remove the lanyard from its packaging.
  13. Remove the attachment loops from the lanyard.
  14. Thread the attachment loop through the top corner hole in the PCB and loop it over the clip.
  15. Repeat for the other corner.
  16. Reattach the clips to the lanyard.
