QuinLED-Dig-Quad Soldering guide

Back to index page

This guide is for the v1 revision 6 board, please see revision history here

To build a QuinLED-Dig-Quad board I have compiled a video guide where we go through all the steps of soldering one together, you can pause at each step and follow along with your own board! Next to that below it is an image guide outlining all components and in what steps I advise to solder them to the board. With both combined and the board being designed in such a way that most people, even new to soldering, should be able to do it!

I know soldering seems daunting at first, but with some decent equipment I think anyone should be able to solder a working board together!

 

 

 

Soldering component highlight guide

Step.1 – Backside – Resistors

1x 0805 16v 4.7K

1x 0805 16v 3.6K

Step.2 – Backside – Capacitors

DIY soldering step 2: the SMD capacitors highlighted on the back of the QuinLED Dig-Quad

6x 0805 16v 0.1uF (100nF)

2x 0805 16v 0.3uF (330nF)

1x 0805 16 10uF

Step.3 – Backside – Polyfuse

DIY soldering step 1b: the polyfuse position highlighted on the back of the QuinLED Dig-Quad1x 1206 PTC/Poly/SMD fuse 750mA – 1000mA

Step.4 – Backside – Diodes

6x SS24 Diode

(Because of issues with some level-shifters it’s current recommended to bridge the Top SS24 diode fixing the issue)

Step.5 – Frontside – LED

Step.8 – Pin Headers

DIY soldering step 7: the pin headers highlighted on the front of the QuinLED Dig-Quad

1x 7 pins

1x 6 pins

2x 2pins

Step.9 – Temperature Sensor

DIY soldering step 8: the temperature sensor highlighted on the front of the QuinLED Dig-Quad

1x TO-92 Dallas temperature sensor

Step.10 – Screw Terminals

DIY soldering step 9: the screw terminals highlighted on the front of the QuinLED Dig-Quad

Step.Optional – 5vEXT Screw Terminal

DIY soldering step 9b: the 5vEXT terminal highlighted on the front of the QuinLED Dig-Quad

Only needed when feeding board from 2 power supplies, please see dedicated article here

Step.11 – Female Headers + ESP32

DIY soldering step 10: the female ESP headers highlighted on the QuinLED Dig-QuadPut in Female Headers, insert male headers into female headers, put ESP32 on top

Solder top of ESP32 first, then solder bottom of the board

Step.12 – Voltage Regulators

DIY soldering step 11: the voltage regulators highlighted on the front of the QuinLED Dig-Quad

1x TO-220 LM7809

1x TO-220 LM7805

Step.13 – Large Capacitors

DIY soldering step 12: the large capacitors highlighted on the front of the QuinLED Dig-Quad

2x 16v 1500uF

Step.14 – Set the voltage jumpers

DIY soldering step 13: setting the voltage jumper to the correct position on the QuinLED Dig-QuadLast step is to set the input power jumper to the correct position!

if 5v LEDs set the Jumper over the 5v pins

if 12v LEDs set the Jumper over the 12v pins

if 5v/12v LEDs with a separate power supply for the LEDs and a 5v power supply for the board, set jumper over 5vEXT pins

 

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.
