Small PCB carriers break out Hall effect, electrically isolated SOT-23 current sensors into ready-to-use modules for measuring bidirectional currents. They deliver low current-path resistance, broad bandwidth and low-voltage logic compatibility, with analogue outputs that interface easily to microcontroller ADCs and data‑acquisition equipment.
Micro and compact footprints give a choice between minimal board space or sturdier layouts for heavier loads. Typical uses include motor and power-system monitoring, battery management, overcurrent detection and power profiling. Reliability comes from solid PCB trace design and isolation, while simple pinouts and standard headers speed prototyping and integration.
