QuinLED-ESP32 Ethernet Compatibility

pre-release article, subject to change!

While developing the Ethernet option for the QuinLED-ESp32 and the existing QuinLED-Dig boards I tried to take compatibility into account as much as possible. Sadly it wasn’t possible to keep all functions when adding the ethernet option to the QuinLED-Dig-Uno v2 and QuinLED-Dig-Quad v1 boards. For this new versions are introduced at the same time as the Ethernet option became available.

Below will be information to determine what kind of limitations you might encounter using a Dig-Uno v2 or Dig-Quad v1 board with the new Ethernet board! First will be a known issues list, then a list in reverse to highlight what remains working perfectly fine with the old versions of the boards!

Known issues

All of the below issues have been “fixed” in the QuinLED-Dig-Uno v3 and QuinLED-Dig-Quad v2. Remember, all these issues only apply when using the new QuinLED-ESP32 Ethernet board with the older QuinLED-Dig-Uno v2 and QuinLED-Dig-Qaud v1 versions!

QuinLED-Dig-Uno v2

  • No Temperature Sensor
  • No Q1-Q4 pins
  • No Audio Input
  • No Button Input

QuinLED-Dig-Quad v1

  • No Temperature Sensor
  • No Q1-Q4 pins
  • No Audio Input
  • No Button Input
  • No LED4 output
  • No 12v LEDs
    • This can be fixed by replacing the Linear power regulators on the board as shown in this article!
    • Alternatively you can switch to using the 5vEXT function!

Wait, what is working?!

I get the above might seem like a lot, but let’s take a look at the primary functions of the boards and what remains working!

QuinLED-Dig-Uno v2

  • Multi-Channel LED output using LED1 (L1_D) and LED2 (L1_C)
  • 5v or 12v power input and LEDs
  • All other board functions such as high power handling, onboard fusing, level-shifters, capacitors, etc.

QuinLED-Dig-Quad v1

  • Multi-Channel LED output using LED1, LED2 and LED3
  • 5v power and LEDs
  • 12v LEDs while using the 5vEXT function
  • All other board functions such as power distribution, onboard fusing, level-shifters, capacitors, etc.

As you can see, all main functions of the board still work perfectly on the QuinLED-Dig-Uno v2 and most main functions also remain working on the QuinLED-Dig-Quad v1! Sadly the linear regulators on that one overheat when using 12v LEDs, but this can be easily fixed by using the 5vEXT function or, if you can solder yourself, by replacing the linear regulators with the one from the QuinLED-Dig-Uno.

If these limitations are an issue in your proposed setups, sadly the only fix for that is to either keep using the boards with WiFi or build/purchase a newer version of the boards.

Tight pin spacing

Since the new boards weren’t exactly planned out to use double pin rows like the new versions do, at first glance it looks like there are pin fitment issues. In my experience though I have always been able to fit the new modules and pins onto the older version boards. None of the pins touch (although visibly the do look close) and functionality is as listed above.

If you are uncomfortable with the pin spacing and the visible aspect of it, you can always snip off the outer rows of pins and one extra front pin (9 pins vs 8 pins highlighted in the black silkscreen on the top of the board). That QuinLED-ESP32 Ethernet module will remain perfectly functional for on the older version of the boards but it might break some functions on the new version of the boards!
