The INA219 I2C current sensor MCU-219 is an electronic module designed to measure voltage and current accurately in direct current (DC) systems. This sensor uses the INA219B-IC chipset and communicates via the I2C protocol, making it easy to integrate into electronics and Arduino projects.
Thanks to its ability to measure voltages up to 26 V and bidirectional currents, it is perfect for applications such as battery monitoring, solar systems, and any project that requires precise control of power consumption.
Main features
- Chipset: INA219B-IC for accurate current and voltage measurement.
- Operating voltage: Compatible with 3.3V and 5V.
- Measurement resistor: 0.1 Ohm, 1% tolerance, 2W.
- Maximum measurement voltage: up to 26 V.
- Dimensions: 25 x 22 x 12 mm, compact and easy to integrate.
- Connectivity: I2C protocol for simple communication with microcontrollers.
- Included accessories: 6-pin header and 3.5 mm PCB terminal block for secure connections.
Typical uses
This sensor is ideal for electronics projects that require real-time power monitoring, especially in Arduino-based systems. It is commonly used for:
- Measuring current and voltage in rechargeable batteries.
- Monitoring solar panels and photovoltaic systems.
- Robotics and automation projects that need power control.
- Electronic measurement equipment and prototype development.

Customer Questions & Answers
What voltage and current range can the MCU-219 module measure with the INA219?
The module can measure voltages of up to 26V DC and currents determined by the 0.1Ω, 2W shunt resistor, which typically corresponds to around 2A maximum, depending on thermal dissipation and the acceptable voltage drop.
What exactly is included in the box, and what are the sensor dimensions?
The box includes the board with the INA219 sensor already mounted, a 6-pin header (for breadboards or other connectors) and a 3.5 mm PCB terminal block. Dimensions are 25 mm x 22 mm x 12 mm.
Which microcontrollers is the MCU-219 compatible with, and what voltage is required to power the module?
The MCU-219 is compatible with microcontrollers that support I2C/IIC such as Arduino, ESP32, Raspberry Pi and compatible boards. It can be powered with 3.3V or 5V, depending on the host system.
Is any special procedure required to install the sensor and ensure accurate measurements?
It is recommended to solder the header and terminals firmly, and to place the sensor as close as possible to the measurement point to minimise voltage drop. It is important to keep connections short and well insulated from the electrical environment.
What are the main differences between the MCU-219 and other current sensors such as the ACS712?
The MCU-219 uses differential measurement with a shunt resistor, which gives greater low-level accuracy (±1%) and supports bidirectional monitoring and higher voltages (up to 26V), whereas the ACS712 uses Hall effect, has less resolution at low currents and limits the voltage to 5V.
What is the INA219 I2C current sensor MCU-219 used for?
It is used to measure voltage and current accurately in DC systems, allowing power consumption to be monitored in electronic projects.
Is it compatible with Arduino?
Yes, the sensor uses I2C communication, which makes it compatible with Arduino and other microcontrollers that support this protocol.
What is the maximum voltage range it can measure?
It can measure voltages up to 26 V in direct current.
What is included with the product?
It includes a 6-pin header and a 3.5 mm PCB terminal block to make connection on breadboards easier.
Is the product available for immediate purchase?
The product is currently out of stock. It is recommended to check alternative products in the Arduino sensors category.
