NOYITO Analog Current Sensor Module INA169 2.7V to 60V DC Current Sensor Breakout Module

Worked. Rl 10k and rsense is 0.1ohms . Look at the schematic of this board which is in its photo slides. One thing before power look and see the labels . Double look at the labels vin+ and vin-. Remember do not put any voltage directly across on this pins. The current has to flow thru the Rsense vin+ then to your load vin- and the other side of load is grounded. LOOK at the schematic in the vendor's photo slide. With the default component on the board of 10k at vout and the Rsense of 0.1ohms you get 1v/1a. My setup worked for as low as 1.6v . But the spec lowest voltage is 2.7v . I like the module for it 1v/1a voltage output. One more time look at where vin+ label is located because it not on the top, if VCC is the top. Also the "load resistor" label on the board is Not your load that you are trying measuring the current of.
