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

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±10 A range with galvanic isolation. It features an analog VOUT output with a sensitivity of 200 mV/A and a 150 kHz bandwidth, enabling fast and precise readings in dynamic systems. The module operates over a wide temperature range of -40°C to 125°C, and the low current path resistance (~1.6 mΩ) minimizes energy loss. Its small size and flexible mounting options make it ideal for prototyping, industrial systems, and space-constrained projects. Pololu 5442

Module based on the TPS2116 enabling automatic switching between two 1.6 - 5.5 V power sources with output through a USB Type-C connector, without USB priority, supporting up to 2.5 A continuous current and reverse current blocking.
