Product description
INA219 current and voltage sensor with Qwiic connector. A module for accurate measurement of voltage, current, and power in electronics projects. Measurement data is transferred via I2C, making the module easy to use with Arduino, Raspberry Pi, and other microcontrollers. Suitable for monitoring power consumption, batteries, and power supplies in both prototypes and finished designs.
The module is equipped with a 0.1 Ω shunt resistor and can measure both positive and negative currents up to ±3.2 A as well as voltages up to 26 V. A solder jumper allows the I2C address to be changed, enabling multiple INA219 modules to be connected to the same I2C bus.
INA219 is a very popular integrated circuit from Texas Instruments.
