TOOGOO(R) GY-219 INA219 I2C Bidirectional DC Current Power Supply Sensor Module (purple)
Description
- 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 +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.

TOOGOO(R) GY-219 INA219 I2C Bidirectional DC Current Power Supply Sensor Module (purple)A precision amplifier measures the voltage across the 0.1 ohm, 1% sense resistor. Since the amplifier maximum input difference is +/-320mV this means it can measure up to +/-3.2 Amps. With the internal 12 bit ADC, the resolution at +/-3.2A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is +/-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-. We have an Arduino library right now that will do all the gain, range and math for you - just plug and go! We'll have a more detailed tutorial up shortly.Uses the INA219B chip0.1 ohm 1% 2W current sense resistorUp to +26V target voltageUp to +/-3.2A current measurement, with +/-0.8mA resolutionThis board ip uses I2C 7-bit addresses 0x40, 0x41, 0x44, 0x45, selectable with jumpersPackage Included: 1 X INA219 GY-219 Bi-direction DC Current Power Supply Breakout SensorNote: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
