So sorry for my late reply. Thank you for precise tips and I understand the points to care!

@ajb2k3
Thank you for reply!
I understand how to connect from one pin.
Then I need to choose each cables between strips which has allowable current 4A, isn't it?

@Thrasher
At first I hoped I could use thin cables to each strips from each pins.
I should research about 74HC595. Thanks!

@ajb2k3
So how could I add more pin for controlling five strips each from portA??


@ajb2k3
Thank you for your precise explanation!
So I can still use M5Stack's unit cable and PaHub!

I checked PaHub code above example here and tried to use UIflow.
https://docs.m5stack.com/#/en/unit/pahub

But I can't click the number and can't expect how programming..
Maybe I have to ask other question thread~
Thank you so much!

So I almost can't M5Stack's unit cable which I bought haha.
I just wonder which pins of M5Stack could I connect to?
I know M5Stack has only two DAC pins.
Could you tell me which good extension device??
thank you so much!

@thrasher
I hope I can make it with supplying from USB Power like Apple USB adaptor!
Could you tell me more detail about that?
