REXQualis Electronics Basic Kit: A Comprehensive Review

The REXQualis Electronics Basic Kit is an extensive collection of over 300 sensors and components designed for fun and simple electronic projects. This kit is perfect for beginners, hobbyists, and students looking to explore the world of electronics. In this review, we will delve into the various components included in the kit, their features, and the overall value it provides.

Components and Features

The kit comes with a wide range of components, including resistors, LEDs, transistors, integrated circuits, and more. The resistors are available in 10 different values, ranging from 10R to 1M, with 10 pieces of each value, except for 220R, which has 30 pieces. The LEDs are divided into 5 colors – yellow, blue, green, red, and white – with 5 pieces of each color.

One of the standout features of this kit is the inclusion of a breadboard power supply, which comes with a USB power cable. This is a rare find in most electronics kits, and it provides a convenient way to power your projects. The breadboard power supply has two power modes: M/M USB power cable and 9V 1A DC adapter (not included).

The kit also includes jumper wires, which are essential for connecting components and creating circuits. The jumper wires are available in two types: male-to-male and male-to-female Dupont wires. The male-to-male jumper wires are perfect for connecting components on the breadboard, while the male-to-female Dupont wires are ideal for connecting components to the breadboard.

Notable Components

Some of the notable components included in the kit are:

• 74HC595: an 8-bit shift register with three-state parallel outputs, commonly used for indicating multipath LEDs and driving multi-bit segment displays.
• 4N35: a 4-terminal universal optocoupler that blocks electrical connections and interference, commonly used in signal isolation transmission and switching power supply feedback control.
• Buzzer: an active buzzer that generates a tone using an internal oscillator, requiring only a DC voltage to operate.
• PN2222 NPN Transistor: a general-purpose transistor that can be used as a switch to control the current of a motor.
• 1N4007 Diode: a device that allows current flow in only one direction, commonly used in circuits to prevent backflow of current.
• Electrolytic Capacitor: a type of capacitor that uses an electrolyte to achieve a larger capacitance, commonly used in power supply filters and audio circuits.
• Ceramic Capacitor: a type of capacitor that uses a ceramic material as the dielectric, commonly used in high-frequency applications and audio circuits.

Packaging and Organization

The components are carefully bagged and labeled, making it easy to identify and organize them. The resistors, LEDs, transistors, and integrated circuits are individually packaged and stored in a sturdy box, ensuring safe and secure storage.

Conclusion

The REXQualis Electronics Basic Kit is an excellent choice for anyone looking to start or expand their electronics projects. With over 300 components, including a wide range of sensors and parts, this kit provides a comprehensive foundation for learning and experimenting with electronics. The inclusion of a breadboard power supply with a USB power cable is a significant advantage, making it easy to power and test projects. The kit’s organization and packaging are also noteworthy, ensuring that components are safe and easy to access.
