I have not seen anything posted. But I am going to assume that Ron's Pi Matrix board get soldered to the top of the Raspberry Pi?

Thanks

NO! - solder a 40 Pin FEMALE connector to the Matrix Board, then plug it on to the Pi

Female connector goes thru holes from bottom to top. Solder Top side.

Where is Ron's board documented?
Is there a schematic? Is it open source?

https://ronsholidaylights.com/raspberry-pi-matrix-adapter/ That's about all you'll find. That being said, it sets up pretty easily and works well.

Does he sell these? Where?
It looks neat, but after the experience with rpm, I don't use/buy stuff that has no info available.

I know their store is taboo here, but I am just answering the question:

Once you install it, just use the matrix settings in FPP to run it.

Ron is out of the green site and sold thru Reynard Plus Shop

I just purchased 4 boards directly from Ron's site - https://ronsholidaylights.com/raspberry-pi-matrix-adapter/.
They got delivered in 3 days - there are well made and come with connectors.
I am very pleased.

Thanks for the soldering tips!

Ron's designs are great and the schematics/source code are all open source. I have 4 of his controllers, numerous adapters and extended some of his designs for my own specific needs.

I didn't see schematics anywhere for the pi matrix board.

There's a forum on the other site for Ron's Holiday Lights (Vendors Area). You'll find a zip file with "Printed Board Wiring Files" (Eagle schematics/board layouts) and also a zip with Source Code.

That all may not be the latest. Ron was talking about improvements. Waiting for FPP code change. May also want to look at the FPP site for this topic.

is it normal for the 4 chips on top of Rons board to get really hot?

I've not noticed that with mine

No, I have sever and they don't even get warm

Did for me once, when I plugged the wrong power supply in. Then they didn't work any more.

Any thoughts on why mine are getting hot? It was too hot to touch. Not all of the panels would light. This is only a 2x3.

I would triple check all the solder points...looking for brides

I think I see the issue. Is the capacitor polarity wrong? All of the solder looks ok no bridges.

Yep, the electrolytic cap is in backwards.
I would no longer trust it.

Good catch!

When you say no longer trust, do you mean the cap or the entire board? Think I can just replace the cap?

I would start with the cap.
then test it. Hard to say if the chips are fried or not.

Ok so just switching the cap it now works but I have strange results with color.

All 6 are connected to output 1

What happens if you took all 6 from output 2 or 3. Just changing cable on the Matrix board and telling FPP to use output #2

JCook

Thanks grumpy,

That fixed it, so maybe one of the chips is fried from the capacitor issue?

I'm use Rays panels, anyone know what voltage I should be set to?

P10 should run at or slightly under 5v.

I learned today that they can have ghosting with the voltage too high.

According to TI ghosting is caused by: "Ghosting, spike noise, or phantom noise are unwanted lighting effects caused by Anode gate "float" which can occur in time-multiplexed LED driver. Since LED lamps (PN junction of diodes) have relatively high levels of capacitance, their residual charge can keep triggering capacitive charge transfers between the floating nodes. And every time there's forward electron flow through a PN junction."

TI has a part to fix this issue, which is probably not available on the cheaper panels.

I just know that a friend was having ghosting during a sequence, turned down his voltage a little, and it went away. I have also read that having the UI open in FPP can cause it. Mine never did either.

What strange color? I think it looks purdy!
