Ideal Diode Reverse Voltage Protector - reverse voltage and current protection module 4-60V, 20A

This compact (0.4″ × 0.5″) switching step-down (or buck) voltage regulator takes input voltages up to 50 V and efficiently reduces them to 9 V while allowing for a maximum output current of 600 mA. It has a very low dropout, so it can be used with input voltages that are within a few hundred millivolts of its output.

This shield makes it easy to control two high-power DC motors with your Arduino or Arduino-compatible board. Its dual robust VNH5019 motor drivers operate from 5.5 to 24 V and can deliver a continuous 12 A (30 A peak) per motor, or a continuous 24 A (60 A peak) to a single motor connected to both channels. Pololu 2507

Module with encoder and RGB backlight. It has an unlimited range of motion and is perfect for e.g. lighting control. Pimoroni PIM522

The pad for use with shallow Feather series contains two TB6612 chips that allow you to control DC motors or stepper motors. The I2C interface is used to communicate with the overlay. Adafruit 2927

A module that provides a regulated, galvanically isolated power supply. It allows easy changing of the output voltage from 5 V to 3.3 V using the voltage selection pin (VSEL). Galvanic isolation between input and output effectively prevents problems related to ground loops and ground currents, ensuring stability and protection of the system. Pololu 5384
