INA219 High Side DC Current Sensor Breakout
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 detach your load. Usage is simple. Power the sensor itself with 3 to 5VDC and connect the two I2C pins up to your microcontroller. Then connect your target power supply to VIN+ and the load to ground to VIN-.
- 0.1 ohm 1% 2W current sense resistor
- Up to +26V target voltage
- Up to ±3.2A current measurement, with ±0.8mA resolution
- This board/chip uses I2C 7-bit addresses 0x40, 0x41, 0x44, 0x45, selectable with jumpers
