LDR Pre MkII - LDR volume control and I/O switching

manniraj · 2019-12-24 12:30 pm

One more quick question, regarding the power pins I see that there is one extra named "Relay control" on the new board compared to the old one. What is the purpose of this relay control?

zdr · 2019-12-25 11:15 pm

To control power AMP. High is ON.

External i/o pcbs?

Hi Neb

Can I use these 4x2 i/o boards with the MK II board/code? Since I have them I would like to use latching relays for my peace of mind.

Is there a BOM and a wiring diagram for those?

Thanks
ElEsido

zdr · 2019-12-28 2:09 pm

No, you cannot.

ElEsido · 2019-12-29 10:14 am

Thanks Ned

Another Q: The BOM Says: C5, 14, 15, 16, 17: 0.1u. I can't find C5 on the silkscreen. On the other hand on the silkscreen there is a C18 100n (=0.1u) which is not in the BOM.

I assume the BOM should say: "C14, 15, 16, 17, 18: 0.1u"?

zdr · 2019-12-29 10:21 am

Can’t check right now, but you are probably right.

hi, C5 is located between R33 and 3 pin connector for IR I assume it is there so you dont need to solder cap to IR_rec pins like in old version of LDR. I populated both. And just found out I also put a cap directly to IR-rec pins

Maybe I should just remove one

But it is working nonetheless. Just completed my build everything working great just need to find a case to put it in... Then I can post some of my pictures.

ElEsido · 2019-12-29 9:14 pm

Thank you Ripster! That "C5" marking is very well hidden.

C18 is between analog +5V and GND and probably helps cleaning the voltage.

Just put mine together today.... So far looks successful!

zdr · 2020-01-04 9:57 am

Looks good

A small note: there are four voltage regulators on power supply board and only three voltage inputs on main board. Fourth (O+) is to be used only in case you have issues with OLED injecting noise into D+ line, as dedicated OLED power line. I did not have these issues myself, but with OLEDs coming from China nowadays everything is possible I guess.

Thanks Neb I will keep that in mind if necessary.

I just got it setup and calibrated, what a great device this is.
Thanks for all your efforts.

Now to get a remote....

Hi Neb,

Could I confirm the "bkl" connection on the pcb
And the wiring for the Oled please

danieljw · 2020-01-05 7:43 am

Apologies Neb, I found this information after reading the complete thread.

Looks like I need to modify the display wiring as per the pic as it is a little glitchy. Is this the correct one? I have this display.

zdr · 2020-01-05 4:38 pm

Please use the photo in the ldr user manual on my site.

All fixed and the IR remote works ! thanks Neb

This report would have more information with

option enabled in File -> Preferences.

Ripster · 2020-01-18 9:37 pm

Did you update libraries before compiling, if not maybe you should try this first.. When I imported them they were quite old...

ElEsido · 2020-01-18 10:10 pm

Thanks, Ripster, I updated the libraries and had no success.

Using the latest Arduino IDE I get a somewhat more human readable error report:
