Official 7Semi INA219 3-Channel DC Current Sensor Breakout – 26V 3.2A Max

The 7Semi INA219 3-Channel DC Current Sensor Breakout is a powerful and compact solution designed to deliver accurate, real-time power monitoring across multiple DC loads. This versatile breakout board enables simultaneous measurement of current, voltage, and power on three independent channels, making it an excellent choice for engineers, developers, and hobbyists working on complex embedded systems.

Built around the trusted Texas Instruments INA219, each channel supports high-side current sensing, allowing current measurement without disturbing the load or ground reference. This design ensures reliable and safe monitoring of DC power systems, including battery packs, motors, power supplies, and energy-sensitive electronics. The board supports bus voltage measurements up to 26V, enabling compatibility with a wide range of low- and medium-voltage applications.

The module communicates through a standard I2C interface, allowing easy integration with popular development platforms such as Arduino, Raspberry Pi, ESP32, STM32, and other I2C-enabled controllers. With programmable gain, conversion times, and digital filtering, users can fine-tune performance for high-speed measurements or ultra-stable readings, depending on system requirements.

To simplify development, the INA219 includes internal calibration and power calculation registers, which automatically compute current in amperes and power in watts, significantly reducing firmware complexity. Despite its advanced capabilities, the breakout board maintains low power consumption, making it suitable for battery-powered and IoT applications.

The 7Semi INA219 3-Channel DC Current Sensor Breakout is ideal for applications such as battery management systems (BMS), motor control diagnostics, power supply analysis, robotics, solar power monitoring, and IoT energy tracking. Its compact design, multi-channel capability, and high accuracy make it a valuable tool for both prototyping and production environments.
