ALMOCN 3Pcs INA219 I2C IIC Interface Bidirectional DC Current Power Supply Sensor Breakout Module Monitoring for Arduino Raspberry Pi

INA219 I2C Bi-directional DC Current Power Supply Sensor;Working Voltage:3~5V. The INA219 achieves a maximum error accuracy of 1% over the -40 ° C to + 85 ° C temperature range with a maximum offset of 100 uV. INA219 not only can monitor the pressure drop on the shunt resistor, sensing shunt power supply voltage, at the same time also can calculate the power. The I2C interface has a timeout setting that not only prevents bus lockout, but also provides high-speed mode for up to 3.4 MHz communication requirements. The high precision of the product combines the advantages of 12-bit resolution to help customers minimize the pressure on the shunt resistor, thus minimizing power loss and power consumption and saving board space.
