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.
