Hey all I am tying to determine where the pcb traces are going in order to figure out if this is using the TM1650 or something else. Most of these (This is from a pool pump) 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.
