OUT (analog — VCC/2 at 0A, ±185/100/66 mV per A for the 5A/20A/30A variants)
VCC (5V — the output scale and the VCC/2 zero point follow the supply, so power it from the same 5V the ADC reference uses)
IP+ / IP− (screw terminal — the measured current path, isolated from the logic side; neither screw is marked on the board, so wire it, read OUT, and swap the two if the sign comes out backwards)

नोट्स
Bidirectional: below VCC/2 means current flowing from IP− to IP+. The D1 LED only shows that VCC is present.
The terminal and its traces are the only parts rated for the full current — keep the measured circuit away from the 3-pin logic side.
