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
