Hi Team,

Hi SHH,

For 36-channel, LP5036 used in schemaitic is the option. For 48-channel, we recommend to use 2 pcs of LP5024. TLC5955 or TLC59581 are the 48-channel display RGB driver device, which have more complex communication interface and more expensive.

I think the schematic is OK for LP5036 part.

Hi SHH,

I think the schematic is OK. One thing need to be confirmed is that both units connected ADDR1 and ADDR2 to GND so they have the same chip address. Customer would use them in the same action, right?
