Pixel LED Programming

[PA3040]

Dear All Have a nice day

I brought a pixel LED module from Alibaba which has 6 RGB LED ( Please see the attached image. The controller IC is UCS512C4 . As per the supplier it is DMX type LED
I think DMX address format . I searched in google to find out datasheet for UCS512C4 but I could not find it

Following are the connection

GND
PI
PO
A
B
24+

Pi is data in and po is data out and in for another module ( daisy chaining several of these modules together )

No idea about A and B

I need to program this pixel Module using Arduino without any controller

Still I do not have any idea about protocol of this module

Please advice
Thanks in advanced

Hi,

pin A and B should be the connections for a differential RS-485 signal, have a look at [1].

DMX is definitely using RS-485 interface.

Although the genetal protocol is well documented, there must be a specification of programming details for your module. Also how a chain of modules shall be controlled
