Adapter for the 6-pin JST SH connector (horizontal) with a pitch of 1 mm to the DIP holes, pitch of 2.54 mm. The set includes 3 modules. Pololu 4773

This simple board breaks out all five pins of a USB Micro-B connector to a 0.1″ pin spacing that is compatible with standard perfboards, solderless breadboards, and 0.1″ connectors. Pololu 2586

Pololu 4811 is a set of two JST SH 2-pin side-entry adapters that enable connecting JST SH wires to breadboards and prototype circuits. Thanks to the standard 2.54 mm pitch and the side-entry connector layout, the module facilitates integration in projects with limited mounting space.

This breadboard-compatible module is an alternative to bulky power switches. It uses a small integrated slide switch to control a high-side power MOSFET that can deliver continuous currents up to around 8 A at 4.5 V to 40 V. Pololu 2814

USB Mini-B Connector Breakout Board

Tiny breakout board for TI’s DRV8838 motor driver can deliver a continuous 1.7 A (1.8 A peak) to a single brushed DC motor. Operating voltage range from 0 V to 11 V, built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature. Pololu 2990

A module that provides galvanically isolated, bidirectional I²C communication (SDA and SCL lines), protecting devices from incorrect connections and voltage differences. Thanks to the TI ISO1640B chip, it supports data transfer up to 1.7 MHz. Pololu 5390

The module protects the load against reverse polarity to -60 V and blocks the flow of reverse current to the power supply. It uses the LM74700-Q1 ideal diode controller and a MOSFET transistor. Thanks to its low impedance (10 mΩ), it supports currents up to 10 A continuous and 00 A transient, providing reliable protection and the possibility of easy assembly. Pololu 5382

This tiny logic level shifter features four bi-directional channels, allowing for safe and easy communication between devices operating at different logic levels. Pololu - 2595

TB6612FNG Dual Motor Driver Carrier

The module protects the load against reverse polarity to -60 V and blocks the flow of reverse current to the power supply. It uses the LM74700-Q1 ideal diode controller and a MOSFET transistor. Thanks to its low impedance (3 mΩ), it supports currents up to 20 A continuous and 50 A transient, providing reliable protection and the possibility of easy assembly. Pololu 5388

This ideal diode module allows for safe connection of two power supplies to a common output point, preventing reverse current flow. Built-in 20mΩ resistors allow for simple voltage compensation and load balancing between the power supplies. The board offers flexible input and output connectors, facilitating integration into industrial and hobby systems requiring high power reliability. Pololu 5398

A switching converter that regulates 24V voltage from an input range of 2.6V to 20V. It offers high efficiency of 70-95% and the ability to operate with a continuous input current of up to 900mA and a peak current limit of 2.2A. With a switching frequency of 1.6MHz and a power-saving mode, it is suitable for both high-performance and low-power applications. Pololu 5588
