A3221 Triple-Channel Shunt Current & Voltage Sensor Board – Power Supply Monitor
The INA3221 is a triple-channel, high-side current and bus voltage monitor designed for accurate power-supply monitoring. It measures both shunt voltage drops and bus supply voltages across three independent channels, communicating via an I²C- and SMBUS-compatible interface.
With programmable conversion times and averaging modes, the INA3221 allows flexible measurement configuration. It also includes programmable critical and warning alerts to detect multiple out-of-range conditions on each channel, supporting reliable system monitoring and protection.
The device senses current on buses ranging from 0 V to 26 V and operates from a single 2.7 V to 5.5 V supply, drawing 350 µA (typical). It is specified for operation across a wide –40°C to +125°C temperature range and supports four programmable I²C addresses for system integration.

Arrived very quickly and worked a treat.
This product is most likely. Compact and easy, daily use. 😉
Very good repair set at an excellent price! Arrived on time and came well-packed. Very pleased with it. Recommended seller.
Nice doing business, product was as described in description. Works as Indented, thanks.
For use at my soldering station to keep fumes out of my eyes
