Matrix Membrane Keyboard 4x4 Modulo

Signal generator including the AD9851 chip, it has two sinusoidal outputs and two square outputs.

The DC-AC 12A solid state relay has a 3-32VDC input and a 24-380VAC output. It has a maximum load capacity of 12A.
It has a long operating life and high reliability, a compact size. This relay switches very quickly. Solid State Relay SSR-25 DA 12A DC-AC Output 24V-380VAC 

SONOFF D1 Smart Dimmer Switch is a smart dimmer switch that offers smart light control solutions perfect for your home or workplace, controlled either by the eWeLink application, via 433MHz RF control or by voice assistants such as Alexa or Google Home.

Create your own scenes, turn the light on at the most appropriate level, or schedule it at the times you want

This module is a three way switch ( COM, NO and NC ) that uses the intensity of the ambient light to control directly the load at the output. Its adjustment potentiometer allows changing the sensitivity and setting the start threshold of the relay. The relay is energized when it is darker than the threshold.

Impressive, professional, high-definition camera module. Official product of Raspberry Pi.

The official Raspberry Pi HQ Camera includes a 1/3" (8.5mm) Sony IMX477 sensor with 12.3MPx resolution and up to 50% increased sensitivity of pixels per area, offering greater sensitivity to light.

It is specially designed to work with CS or C-mount interchangeable lenses (CS-C adapter included). It allows you to use both fixed and varifocal lenses, and you can also use other lenses such as M12 lenses by using an M12 to CS mount converter.

This module specially designed for Arduino will allow you to generate a light of any color (RGB) quickly and accurately.
The SMD LED Module RGB, consisting of an LED capable of creating any color using RGB, has a PWM voltage input with three pins.
These are capable of shining in a wide range of colors thanks to the mixture of the three primary colors (red , green and blue). These types of diodes are called RGB and are made up of three red, green and blue diodes in the same package.
Thanks to the variation of the intensity of these three diodes, we can create a composition of colors. With this led you can handle more than 16.5 million colors.
