Hello I have a RaspberryPi 3b+ that I want to measure it's curent/voltage/power consumption in realtime by using an Arduino + INA219. So I have to configure/cut the power supply cables of the RaspberryPi in order to make the right connections with the INA219. Is there any other approach without destroying the powersupply cables?
Why do you think cutting one wire is going to destroy it?

Ok, is there any other way?
I have made a short cable with the sensor in it and two connectors - one male and one female on the ends and plugged the power cable into the short test cable - have also done the same using some screw terminals when the wires were going to a terminal strip in a panel.
Are there any usb micro to usb cables that can handle 2.5A - 3A current??

No.
Hello, Can I update this circuit: Overview | Adafruit USB Power Gauge Mini-Kit | Adafruit Learning System to measure at maximum 3A? As I saw from this: INA169 Breakout Board Hookup Guide - SparkFun Learn the INA169 can measure at most 3.5 A with Rs = 0.1 Ohm... Also If I rmove the LEDs, does this affects the circuit's stability??
