Design with Adafruit INA260 in Cirkit DesignerThe Adafruit INA260 is a high-precision current and voltage sensor module that allows for simultaneous monitoring of current, voltage, and power through a single I2C interface. This sensor is ideal for a wide range of applications, including power supply monitoring, battery charging, energy consumption tracking, and load sensing in various electronic projects.
This circuit connects an Arduino Mega 2560 to an INA219 sensor for current and voltage measurement. The INA219 sensor communicates with the Arduino via the I2C protocol, and the Arduino reads and prints the current, bus voltage, shunt voltage, and power values to the Serial Monitor.
Open Project in Cirkit Designer
This circuit features an Arduino UNO microcontroller interfaced with an INA219 current sensor, a 5V relay, and an RGB LED. The Arduino reads current measurements from the INA219 via I2C and controls the relay and LED, potentially for monitoring and controlling power to a USB-connected device.

This circuit uses an Arduino Mega 2560 to interface with multiple sensors, including an Adafruit ADXL326 accelerometer, a pressure transducer, and two MLX90614 IR temperature sensors connected via an Adafruit TCA9548A I2C multiplexer. The Arduino reads data from these sensors and outputs the values to the Serial Monitor.

This circuit is designed for monitoring and displaying sensor data. It includes three INA219 current sensors, a GH1248 Hall sensor, and an SSD1306 OLED display, all interfaced with a Seeed Studio RP2350 microcontroller. The microcontroller reads data from the sensors and controls the display and three LEDs.

Q: Can the INA260 measure negative current? A: Yes, the INA260 can measure current in both directions, from -15 A to +15 A.
Q: What is the maximum voltage that can be measured? A: The INA260 can measure voltages up to 36 V.
Q: How do I change the I2C address of the INA260? A: The I2C address can be changed by connecting the ADDR pin to GND, VCC, SDA, or SCL, providing four different address options.
Q: Is it possible to use multiple INA260 modules on the same I2C bus? A: Yes, you can use up to four INA260 modules on the same I2C bus by setting a unique address for each using the ADDR pin.
