Panel is not working - issues with assembly - no instructions ? about wemos-matrix-shield

[hallard]

Would be helpfull to help if you could post a picture of what you've done.

This version works only with PXMatrix because wiring is not for ESP32-HUB75-MatrixPanel-I2S-DMA (even if you use an ESP32). For use this version

To do tests, you just need to solder the headers no components needed (except ESP of course). Better to add caps if ESP goes into reset.

Hi ! Thank you Hallard. You're right. Here are some photos of the assembly.

Thank you

Hi Hallard.
I'm going to close the issue.

I was hopping for some feedback, but I managed to solve this one. The assembly is well done. My problem is that I had some wemos d1 mini with the sleep solder blob on and that was messing the code and the wemos d1 somehow. Removing the solder on the PAD solve the issues. I discover because I've tried with another wemos I have around and worked perfectly. I've tested with 32x32 and 64x32 panels and both worked wonderfully.
Thank you

Glad you had it working.

You need to remove big capacitor, it will really slow down light change, this one should be 100nF (unpolarized) only, but you also can remove completely and just let 10K resistor and LDR.

Also 4K7 R2 is only used for DS18B20 temp sensor, looks like you don't have it so this resistor is unneeded.
