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

These universal aluminum mounting hubs allow you to mount custom wheels and mechanisms to 8 mm diameter motor shafts. The set includes two hubs, four M3 set screws for securing the hubs to motor shafts, and one 1.5 mm Allen wrench for use with the set screws.

The ACS72981 current sensor module uses the Hall effect to accurately and safely measure AC and DC current, providing electrical isolation of the current path. With a wideband analog output (up to 250 kHz) and low conduction resistance (0.2 mΩ), it minimizes energy loss and offers a fast response time of less than 2 µs. Pololu 5270

Pololu 2512Module with 2-channel DC motor driver for Arduino boards. It allows you to control drives with a supply voltage from 6 to 32 V and a current consumption of up to 0.65 A. Pololu 2512
