CURRENT MEASUREMENT CIRCUIT, CIRCUIT BOARD ASSEMBLY, AND CURRENT DETECTION DEVICE

A current measurement circuit, a circuit board assembly, and a current detection device. The measurement circuit comprises: a PCB substrate (1), N PCB pads (2) connected in parallel on the PCB substrate (1), N patch diverters and N current detecting point wirings in one-to-one correspondence to the N PCB pads (2), and a measurement unit, wherein N is an integer greater than 1. Each PCB pad (2) comprises a first pad (21) and a second pad (22) which are separated from each other, a first end of each patch diverter is electrically connected to the corresponding first pad (21), and a second end of each patch diverter is electrically connected to the corresponding second pad (22). Each current detecting point wiring comprises a first current detecting point wiring (3) and a second current detecting point wiring (4). The first current detecting point wirings (3) are led out from the first pads (21) to be connected to a first end of the measurement unit, and the second current detecting point wirings (4) are led out
