Display 4 digits and 7 Segments

Good afternoon, I need help with understanding the two types of terminals in a diagram of an LED display.

I am gonna put the two diagrams for you to see what i mean:


What are the differences between them?

Which one can I use for that?

I mean, one is digit 1 1, the other is digit 1 12, i do not know which one is correct!

One is common anode, and the other is common cathode.

Edit: Common anode means the anodes are all tied together, and the segment is lit when the anode is connected to power and the individual cathodes are grounded through a resistor.

Common cathode means all the cathodes are tied together, and the segment is lit when the cathode is grounded and the anode gets power from V+ through a resistor.

I know that. What i do not understanding is, one image is different than the other, please help!

Both imagens, (pin12 and pin 1), are same type?
What type they are?

Different manufacturers are free to choose whichever pins they want for their designs. There is no law that they must all choose the same pins for the same purpose.

The internal circuit diagram is just that.
The logic, and I presume the pin numbers, is the other diagram.

So is the same connections?

Can i use the first one or the second one?

I want to put a bigger LEDS on the tm1637. I want to change to bigger LEDS!

Remove this LEDS that comes with the board, and put a bigger. But i do not know which one can i use, in that image, you know what i mean?

This is the question you should have asked in post #1. Only now is your question beginning to make any sense.

Maybe you cannot use either of those that you posted the images of. The display on the tm1637 may not match either of them. Also the spacing of the pins may not match.

Are those 0.36" characters?
They make a 0.56" display.
Just saying.

So, how can i change the LEDS to Bigger using a TM1637 display, and what is the diagram for that, did you know? Do you Know?

What is the question about? How to replace? - desolder the existing lEDs and put a new one.

There are a lot of similar boards in the Aliexpress. Try to look up the scheme or dissemble the board and draw the schematics from the PCB.

PS Your question is cross-post with your new thread, you have to stop identical discussion on the one of two topics.

I am using 5v LEDS

Ok Than.....

The TM1637 drives common anode displays. (The MAX7219 drives common cathode displays and has a serial interface.)

No. Not okay. Do not cross-post. Thread locked.
