  • The INA3221 is a three-channel, high-side current and bus voltage monitor with an I2C- and SMBUScompatible interface.
  • The INA3221 offers both critical and warning alerts to detect multiple programmable out-of-range conditions for each channel.
  • The INA3221 monitors both shunt voltage drops and bus supply voltages, in addition to having programmable conversion times and averaging modes for these signals.
  • The INA3221 senses current on buses that can vary from 0 V to 26 V. The device is powered from a single 2.7-V to 5.5-V supply, and draws 350 uA (typ)of supply current. The INA3221 is specified over the operating temperature range of –40°C to +125°C.
  • The I2C compatible interface features four programmable addresses.

Good Quality Modules and as you can see in the photos uploaded of the INA3221 boards I received they do have the required separate trace connections for each of the 3 channels. Apparently there has been past issue with other brands of INA3221modules whereby the three channels all being connected together, but these modules are designed correctly with separate connections for (VIN1+ VIN1-) (VIN2+ VIN2-) (VIN3+ VIN3-). Read the INA3221 Data Sheet to understand why this is important. With that said, this is the module brand you want to order. Very happy with the purchase.

Quality Modules using it to monitor battery voltage for my generator, added the starter signal, and ATS control since I had extra channels. Connected to an ESP32. Been working great.
