Isolated DC-DC power module designed for safe powering of sensitive electronic circuits, offering galvanic isolation up to 3kVRMS, 5V or 5.5V output voltage, and output current up to 300mA. Pololu 5414

DC motor driver based on the Texas Instruments DRV8263H-Q1. It can control one DC motor in two directions or two motors in one direction from a supply voltage of 4.5-65V and a continuous current of up to 3.5A (limited to 10A). The module offers three control modes: Phase/Enable (PH/EN), PWM (IN/IN), and independent half-bridges. Built-in current sensors and protection features protect against overload, overheating, and reverse power connection. The 3-5V logic control is decoupled from the motor supply, increasing safety and integration flexibility. Pololu 5238

This controller allows independent control of three DC motors using a single I²C bus. It supports motor supply voltages ranging from 4.5 to 44 V and currents up to 0.8 A continuous per channel, making it suitable for a wide range of robotic and mobile applications. I²C communication eliminates the need to generate PWM signals and significantly saves microcontroller pins. The ability to connect multiple controllers on a single bus allows for easy scaling of the system to larger motor counts. Pololu 5085
