RTK-000-006 Soldering Guide

Please Note - This guide was made for a prototype of the debug clip, the video is correct and up to date. 

The changes include the addition of the jumper wire and the Polyfuse & Diode being swapped.

This guide will show you step by step how we recommend to solder the debug clip with ease. If you prefer to solder components in a different order then that's fine! This is how we found it the easiest to solder without much trouble.

Checking Components

Your kit should include the following:

  • 1 - RTK-000-006 PCB
  • 1 - MCP2221 Chip
  • 1 - 0.5A Polyfuse (Yellow component that looks more like a capacitor)
  • 1 - Diode
  • 2 - 47Ohm Resistors
  • 1 - USB B Socket
  • LEDs, 1 Red & 1 Green

Preparing To Solder

You will require the following tools to solder:

  • Soldering Iron! - Most should solder fine for this kit.
  • Solder! - I use Lead Free Solder
  • Wire Cutters - used for snipping the legs after soldering. A nice pair of wire cutters are cheap and will do the job best.

You may also find the following useful!

  • Blu-Tack - Handy for keeping the PCB in place at points.
  • Soldering Iron Cleaning Equipment - I use brass shavings to clean my iron's tip and they work pretty well and cost around £5 for a pot. If you don't then a sponge which normally comes with your iron should do the job well.
  • Bright light - I find having a very bright light over what I'm soldering helps a lot. Normally I can see a bridge very clearly if I do one. (I use one which came with a mini photobooth kit).

Here's a picture! 

Take care when soldering! Don't touch the hot end, Its hot!


If you prefer you can also watch the video version, if not then the guide is below the video.

Beginning soldering!

Start by bending the legs on the two resistors and diode to the rough size of the PCB.

Next push into the PCB and bend slightly to keep in place. Next solder.

Now trim the leads with the wires and then re-solder the joints for a better finish.

Before Re-soldering

After Re-soldering

Next push the IC into the area taking note that the notch aligns with pin one indicated by being the square pad. Be careful when bending the pins and then solder.

Now solder on the USB B socket starting with the two support pins and then the 4 Data & Power pins in the middle.

Next populate the board with the Polyfuse & LEDs, The polyfuse doesn't matter which way round you put it in but both the LEDs positive leads (longest) must face the middle towards the plus and then solder!

Finally check that there are no solder bridges and re-heat any joints that you're not happy with (and apply a tiny bit of solder or flux at the same time).

You're now ready to go!

Your debug clip should now be fully soldered and ready to use!
