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.

ESC controller module for a brushless motor with a current capacity of up to 40 A. It can work with LiPo packages from 3S to 6S. Uses BLHeli_32 software. Skystars Talon32

HDMI-USB adapter dedicated to video capture and transfer to devices with USB type A connector. Waveshare HDMI to USB Adapter

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
