Following tools are necessary to assemble the USB hub:

  • Soldering iron with tiny tip (or SMD rework station)
  • Solder
  • Solder flux
  • A couple of tweezers
  • Bench magnifying glass or microscope
  • Nipper or cutting tool

During soldering try to solder small SMD components first. To overcome most of the problems we recommend to solder this board in the following order:

  • Solder U1 (PIC16F630) IC first.
  • C6
  • J6, J7

After soldering the above components, connect the "PICKit 3" programmer to the J2 terminal and flash the U1 MCU. The programming procedure is described in the following section of the documentation.

Following the firmware upload, solder rest of the components to the PCB.
