The module protects the load against reverse polarity to -60 V, but does not block reverse current, which is desirable in applications such as motor control. It uses the LM74500-Q1 controller and a MOSFET transistor. Thanks to its low impedance (5 mΩ), it supports currents up to 12 A continuous and 40 A transient, providing reliable protection and the possibility of easy assembly. Pololu 5381

3-Pin Female JST PH-Style Cable (30 cm) with Male Pins for 0.1" Housings

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±30 A range with galvanic isolation. It features an analog VOUT output with a sensitivity of 66.7 mV/A and a 150 kHz bandwidth, enabling fast and precise readings in dynamic systems. The module operates over a wide temperature range of -40°C to 125°C, and the low current path resistance (~1.6 mΩ) minimizes energy loss. Its small size and flexible mounting options make it ideal for prototyping, industrial systems, and space-constrained projects. Pololu 5443
