About this product

The 7Semi INA219 3-Channel DC Current Sensor Breakout enables accurate current, voltage, and power monitoring across three independent channels. Each channel measures bidirectional DC current up to ±3.2 A and bus voltage from 0 V to 26 V DC. Three onboard INA219 current sensor ICs provide reliable 12-bit digital measurements through the I²C interface. Dedicated I²C addresses—0x40, 0x41, and 0x42—allow all three channels to operate simultaneously. The module supports 3.3V and 5 V controllers, including Arduino, ESP32, STM32, and Raspberry Pi. It is ideal for battery monitoring, solar systems, power supplies, DC loads, and IoT power-management applications.

Key Features

  • Three independent INA219 channels for simultaneous DC current, voltage, and power monitoring.
  • Measures bidirectional current up to ±3.2 A per channel and bus voltage up to 26 V DC.
  • Integrated 12-bit ADC delivers digital measurements with gain error up to ±0.5%.
  • I²C interface uses dedicated addresses—0x40, 0x41, and 0x42—for easy multi-channel operation.
  • Compatible with 3.3 V and 5 V systems and includes dual Qwiic connectors for convenient integration.
  • Supports selectable shunt-voltage ranges of ±40 mV, ±80 mV, ±160 mV and ±320 mV.
  • Measures current flow in both directions across three independent channels.
  • Supports programmable conversion times and averaging for flexible measurement performance.

Includes:

  • 1 × 7Semi INA219 3-Channel DC Current Sensor Breakout

  • 1 × 2.54 mm Pin Header
