In this product guide we can learn description around power supply, current sensor, voltage drop, breakout, current measuring, and board. Many things regarding supply, offset, functions, sensor, and circuit are presented inside this product guide.
This product guide tells the reader discussion regarding load voltage, binary, load, shunt voltage, and ground reference. Here are grabbed from the product guide:
The INA219B breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can use this breakout to measure both the high side voltage and DC current draw over I2C with 1% precision. W hy the High Side? Most current-measuring devices such as our current panel meter are only good for low side measuring. That means that unless you want to get a battery involved, you have to stick the measurement resistor between the target ground and true ground. Since the voltage drop across the resistor is proportional to the current draw, this means that the ground reference will change with varying current.
Giving more content, the product guide gives you more regarding pin, sensor reading functions, voltage, resistor, and current.
