measuring three independent power sources Nov 28, 2019 5:21:32 GMT -8 Quote Select PostDeselect PostLink to PostMemberGive GiftBack to Top Post by hbarth on Nov 28, 2019 5:21:32 GMT -8 I currently have an INA3221 module from another supplier in use. However, this can apparently only measure three different currents. Only one voltage source is possible.Now I ordered a Grove INA3221 from Amazon.com. Is it true that the voltage of three different and independent power sources can be measured?How can you change the default address 0x40 - e.g. on 0x41?
