Pololu 4814 is a set of two JST SH 4-pin top-entry adapters that allow easy integration of JST SH wires with breadboards and prototype boards. With support for voltages up to 50 V and currents up to 1 A per pin, these adapters are suitable for a wide range of applications in electronics and automation.

Pololu 4810 is a set of two JST SH 2-pin adapters that enable connecting JST SH wires to breadboards or prototype circuits. Thanks to compatibility with JST SH wires and the standard 2.54 mm pitch, the adapter facilitates quick prototyping and integration in electronic projects.

Module with a distance sensor with a range of up to 130 cm. It has a digital output that generates a pulse with a width proportional to the measured length. Pololu 4071

Pololu 2512Module with 2-channel DC motor driver for Arduino boards. It allows you to control drives with a supply voltage from 6 to 32 V and a current consumption of up to 0.65 A. Pololu 2512

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 16 A at 4.5 V to 40 V. The board features reverse-voltage protection and also makes it easy to control the MOSFET with an external switch or the digital output of a microcontroller.

The ACS72981 current sensor module uses the Hall effect to accurately and safely measure AC and DC current, providing electrical isolation of the current path. With a wideband analog output (up to 250 kHz) and low conduction resistance (0.2 mΩ), it minimizes energy loss and offers a fast response time of less than 2 µs. Pololu 5270

The Step-Down D24V6F3 Buck Voltage Regulator module gives the output voltage of 3.3V with a wide input voltage range of 4.8-42V and a maximum output current of 600 mA. Pololu 2106

This RC switch converts hobby radio control pulses to digital on/off signals for use in RC switch and simple RC adapter applications. One output indicates the presence of a valid RC signal, and the other indicates whether the switch is active. The activation threshold and direction are configurable, and a safe-start feature reduces the likelihood of unexpected activation. Pololu 2801
