Product Overview
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 3.3 V 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.
