Sorry that there’s wrong information above for Orin NX.
Unit:
in*_input → milliVolt
shunt*_resistor → microOhm
curr*_input → milliA
curr1_input = in4_input / shunt1_resistor
curr2_input = in5_input / shunt2_resistor
curr3_input = in6_input / shunt3_resistor
curr4_input = curr1_input+curr2_input+curr3_input
in7_input = in4_input + in5_input + in6_input
The shunt resistor should be 5 milliOhm for Orin NX by default. (you could check shunt*_resistor)
Please check if the reading on your board matches with the above relationship.
