QuinLED-Dig-Uno Soldering guide

This guide is for boards v2r5 and lower. Please see revision history for differences and/or newer versions

QuinLED-Dig-Uno v2r6 guide is here

To solder the QuinLED-Dig-Uno together I’ve made a video which takes you through all the steps involved. I think anyone should be able to follow along and basically replicate what I do in the video. Just pause the video at each step and do it yourself. I know soldering seems daunting at first, but with some decent equipment I think anyone should be able to solder a working board together!

Beyond this video I also have the highlight picture guide below, once you are doing watching the video, make sure to check that out also!

Soldering Highlight guide

To make soldering even easier I have made some highlighted pictures where you can see exactly where each of the components go per type.

1. SMD Capacitors

4x 0.1 µF

1x 10 µF

2. SMD Resistor

1x 4.7k resistor

3. SMD diodes

These have polarity, mind the stripe on the board and diodes!

1x SS12 diode

2x SS24 diode

4. Level Shifter

1x 74AHCT125N or 74HCT125N

5. Male Pin headers

2x 5 pins

2x 3 pins (red and yellow color)

6. Screw Terminals

1x 2 times terminal (black)

1x 4 times terminal (blue)

7. Female headers + Micro-controller

Set of 2x 8 pin female headers + 2x 8 pin male headers to solder onto the micro-controller

Easiest way to solder these is by making a little “sandwich”  like I show in the video!

8. Fuse holder

Single fuse holder

9. Through-Hole capacitors

1x 8mm x max 8mm height

1x 10mm x unlimited height

10. Optional DC-DC converter

1x DC-DC converter (line up vi and vo)

11. Optional DS18B20 temperature sensor

1x DS18B20 temperature sensor

Ending remarks

Did all of the above? Great, you’re done, go on to either the wiring guide or one of the programming guides from the front page.
