    Current Sensor GYINA219 Module Type A Digital GY INA219 Bidirectional DC current

    + This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219B chip on this breakout to both measure both the high side voltage and DC current draw over I2C with 1% precision.

    + 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. This can cause problems with circuits since electronics tend to not like it when the ground references change and move with varying current draw.

    + This chip is much smarter - it can handle high side current measuring, up to positive 26VDC, even though it is powered with 3 or 5V. It will also report back that high side voltage, which is great for tracking battery life or solar panels.

    + A precision amplifier measures the voltage across the 0.1 ohm, 1 percent sense resistor. Since the amplifier maximum input difference is positive/negative 320mV this means it can measure up to positive/negative 3.2 Amps.

    + With the internal 12 bit ADC, the resolution at positive/negative 3.2A range is 0.8mA.

    + With the internal gain set at the minimum of div8, the max current is positive/negative 400mA and the resolution is 0.1mA.

    + Advanced hackers can remove the 0.1 ohm current sense resistor and replace it with their own to change the range (say a 0.01 ohm to measure up 32 Amps with a resolution of 8mA)

    + We include a 6-pin header (so you can easily attach this sensor to a breadboard) as well as a 3.5mm terminal plug so you can easily attach and detach your load. Usage is simple.

    + Power the sensor itself with 3 to 5VDC and connect the two I2C pins up to your Minicontroller. Then connect your target power supply to VIN+ and the load to ground to VIN-.
