Hey all I am tying to determine where the pcb traces are going in order to figure out if this is using the [**TM1650**][1] or something else. Most of these ([This is from a pool pump][2]) uses the **TM1650** but there are some that use some other chip.

From what I can gather since the chip is covered in silicon is that 2 of the pins (SCL/SDA) are on the correct pins of the chip. Those being pins 2/3 respectively. But the others coming from the LED segment do not seem to match the **TM1650** pin positions?

I have tried to trace them the best I could:

The original image without my color traces:

The front of the PCB:

Here is the schematic of someone who has already done something like this - allthough they had a different version than I do:

I'm not sure where the **C, DP, A,** and **B** traces are going to. With my current traces it looks like this:

It would be great if someone who knows more about traces and such on PCBs to lend me a hand with determining if it's the TM1650 pinout or not and if my traces are even correct as-is.
