5.3 R1_n, R5_n (Rshunt)

Rshunt is unpopulated, but allows the user to solder down a surface-mount shunt resistor between the In+ and In– pads sensed by IN+ and IN– input pins. If used, make sure Rshunt has proper power dissipation for the selected current load and below 5 A. The chosen resistor must have a 2512 footprint.
