INA219 I2C Bi-directional DC Current/Power Monitor Sensor Breakout Module


INA219 I2C Bi-directional DC Current Power Sensor Breakout Module

INA219 Zerø-Drift, Bidirectional Current/Power Monitor With I 2C Interface

Working Voltage 3~5V
Size:25.5 x 22.3mm
Used for I2C port zero drift / bidirectional current / power monitoring sensor module



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)


NA219 can be achieved within the
maximum error accuracy 85C temperature range from -40C to + 1% ,
the maximum offset is 100 uV.
The high-precision products combine the advantages of 12-bit resolution.
This module can be sensed bus voltage range is 0 V to 26 V.
max current 3.2
Requires soldering of header pins (easy!)
Measure high side voltage and DC current draw
