A kit for building a digital signal generator with two output channels. Supports wave types such as sine wave, square wave, triangle wave, sawtooth wave, ECG and random noise

Large momentary button with a diameter of 100 mm with LED backlight. It was based on a limit switch. The housing is black

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

An efficient step-down converter that reduces the input voltage to 3.3 V at a maximum current of 100 mA, offering high efficiency thanks to its low quiescent current (<20 μA). It supports input voltages from 3.3 V to 65 V, has short circuit and overheating protection, making it a reliable and energy-efficient solution. Pololu 5362

A miniature vibration motor generating vibrations at over 12,500 rpm at a voltage of 3 V, ideal for applications in phones, game controllers or medical devices. With its small dimensions (11.6 × 4.6 × 4.8 mm), low current consumption (65 mA) and flexible cover reducing noise, it is an energy-efficient and easy-to-integrate component for tactile signaling.
