INA219 DC Current Power Monitor Sensor Module

INA219 with the industry's highest accuracy and smallest size, not only to monitor the voltage drop across a shunt resistor on the sensing shunt supply voltage, while also computing power
The high-precision products combine the advantages of 12-bit resolution, as much as possible to help customers reduce the pressure drop on the shunt resistor, thereby minimizing power loss and power consumption and save board space. The device can be sensed bus voltage range of 0 V to +26 V.

• NA21 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
• Programmable calibration register can be read in units of ampere direct current, and read the power in watts.
• Up to 128 samples can be averaged to achieve filtering in noisy environments.
• I2C interface has a timeout setting, not only to prevent bus lock, but also provides high-speed mode, to meet the communication requirements of up to 3.4 MHz.
• All properties INA219 are software programmable to support.
• A single power supply, the operating voltage of between +3.0 to + 5.5V.
• Size:25.5 x 22.3mm
• Used for I2C port zero drift / bidirectional current / power monitoring sensor module
