Yeah that's just the photo, the traces keep going to the "JPLED" connector. That might be the 45º angle on the low quality jpg that do not translate. And we have a winner, for some reason the 3.3v connection is...

I had the PCB done by JLCPCB, I soldered only the pins that are used:

Thanks for the suggestion, First I made it work with the audio board and the scanner, I had to add these 2 lines at the top: #include <Audio.h> AudioOutputI2S audioOutput; also I detect the audio board with...

So I've made a PCB only with the TLC59116 chip and the few required resistors to test. I still get the same result. I looked up the chip datasheet, and the address of this chip when A0-A3 are at zero is not 0xC0...

Ah I looked at the schematics and since it was saying 3.3v to 5v power supply I chose 5v (cannot remember why though) but you are right the typical example shows it powered with 3.3v...

Thanks for the suggestions, So I have run that test without the RESET and REXT and also with them (but I'm connecting the resistors on that super small chip holding everything in my hands so I'm wondering how good is...
