INA219 High Side DC Current Sensor Breakout is a 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. it can handle high side current measuring, up to 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.
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. We have an Arduino library right now that will do all the gain, range and math for you – just plug and go! We&apos ll have a more detailed tutorial up shortly.
