The MCU 219 module is a zero drift, bidirectional current/power monitoring integrated circuit (IC) with I2C interface, further strengthening the TI energy-saving electronic product camp. INA219 has the industry's level of precision and size, which can not only monitor the voltage drop on the shunt resistor, sense the shunt supply voltage, but also calculate the power supply. This device is packaged in SOT23 and can provide a small, low-cost solution for digital current sensing of servers, laptops, power supplies, battery management, and in vehicle and telecommunications equipment.

INA219 can achieve an error accuracy of 1% within the temperature range of -40C to+85C, with an offset of 100 uV. The high precision of this product combined with the advantage of 12 bit resolution can help customers minimize the voltage drop on the shunt resistor as much as possible, thereby reducing power loss and consumption, and saving board level space. The bus voltage range that this device can sense is 0 V to+26 V.

Other important features of INA219 include:
a. Programmable calibration registers can directly read current in amperes and power in watts.
b. Up to 128 samples can be averaged to achieve filtering in noisy environments.
c. The I2C interface has a timeout setting, which not only avoids bus lockup, but also provides high-speed mode to meet communication requirements up to 3.4 MHz.
d. All features of INA219 support software programmability.
e. Using a single power supply, its working voltage is between+3.0 and+5.5V.

Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
