NOTE：This kit Not including the controller board.
The Breadboard Power Supply has two power modes:
1) M/M USB Power Cable（included in this kit）;
2) 9V 1A DC Adapter（Not included in this kit）.
Jumper Wires
Jumper wires can be used for pin extension of the experiment board, adding experimental items, and the like. It can be connected very securely to the pins, eliminating the need for soldering and allowing quick circuit testing.
Our kit includes 65pcs male to male jumper wires, 20pcs male to female dupont wires, and 140pcs solderless jumper wires. which are completely adequate for various experiments.
IC 74HC595
The 74HC595 consists of an 8−bit shift register and a storage register with three−state parallel outputs. It converts serial input into parallel output so that you can save IO ports of an MCU. The 74HC595 is widely used to indicate multipath LEDs and drive multi-bit segment displays. “Three-state” refers to the fact that you can set the output pins as either high, low or “high impedance.” With data latching, the instant output will not be affected during the shifting; with data output, you can cascade 74HC595s more easily.
IC 4N35
The 4N35 is a 4-terminal universal optocoupler that blocks the electrical connection between the signal source and the receiver of the signal, which effectively blocks electrical connections and interference. Commonly used in signal isolation transmission, switching power supply feedback control and so on. Common circuits include TV power supply parts (remote control switch, voltage feedback control), switching power supply, electric vehicle charger and many other aspects.
Buzzer
An active buzzer will generate a tone using an internal oscillator, so all that is needed is a DC voltage. A passive buzzer requires an AC signal to make a sound. It is like an electromagnetic speaker, where a changing input signal produces the sound, rather than producing a tone automatically.
To identify them, if you apply a DC voltage to them and it buzzes, it’s an active.As far as commands go if you want to control the pitch, you would need a passive buzzer.
PN2222 NPN Transistor
The PN2222 can be used as a switch that use a little current from the R3 digital output to control the much bigger current of the motor. Because the small DC motor is use more power than an R3 digital output can handle directly.
1N4007 Diode
1N4007 Diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above. For 1N4007 Diode, the maximum current carrying capacity is 1A it withstand peaks up to 30A. Hence we can use this in circuits that are designed for less than 1A. The reverse current is 5uA which is negligible.
Electrolytic Capacitor
Electrolytic capacitor is a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. An electrolyte is a liquid or gel containing a high concentration of ions. Almost all electrolytic capacitors are polarized, which means that the voltage on the positive terminal must always be greater than the voltage on the negative terminal.
Ceramic Capacitor
Ceramic capacitor uses a ceramic material as the dielectric. Ceramics were one of the first materials to be used in the production of capacitors, as it was a known insulator. Ceramic capacitors are usually made with very small capacitance values. Ceramic capacitors are also very small in size and have a low maximum rated voltage. They are not polarized, which means that they may be safely connected to an AC source. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance.
REXQualis Electronics Component Fun Kit Review: A Complete Learning and Prototyping Solution
Introduction to the REXQualis Electronics Fun Kit
The REXQualis Electronics Component Fun Kit is a comprehensive and practical electronics learning package designed for students, hobbyists, engineers, and DIY makers. It provides a wide selection of electronic components and tools that allow users to explore circuit design, embedded systems, and hands-on experimentation.
This kit is especially useful for working with popular development platforms such as Arduino, Raspberry Pi, and STM32, making it a versatile option for both beginners and advanced users in electronics education and prototyping.
Complete Electronics Learning and Experimentation Kit
One of the strongest aspects of this kit is its completeness. It includes more than 400 electronic components and sensors, covering a wide range of basic and intermediate electronics applications. These components allow users to build and test different types of circuits, from simple LED projects to more advanced sensor-based systems.
The availability of such a wide range of components in one kit makes it highly suitable for learning environments, where students need access to multiple parts for experimentation. It also reduces the need to purchase additional components separately, making the learning process smoother and more efficient.
Wide Range of Electronic Components and Sensors
The REXQualis kit includes a carefully selected assortment of electronic components that are essential for circuit design and prototyping. It features resistors, LEDs, transistors, integrated circuits, capacitors, potentiometers, jumper wires, and various sensors.
These components allow users to explore both analog and digital electronics concepts. For example, resistors are used for controlling current, LEDs for visual output, and transistors for switching and amplification. Potentiometers enable adjustable resistance, which is useful for calibration and control experiments.
The inclusion of sensors adds an interactive element to projects, allowing users to work on real-world applications such as temperature sensing, light detection, and signal processing.
830 Tie-Point Breadboard for Easy Prototyping
A key feature of this kit is the included 830 tie-point breadboard. This breadboard provides a flexible platform for building and testing circuits without the need for soldering.
Users can easily insert components and jumper wires to create different circuit configurations, making it ideal for experimentation and learning. The ability to quickly modify circuits encourages trial-and-error learning, which is essential for understanding electronics principles.
This breadboard is large enough to support medium to complex projects, making it suitable for both beginners and more advanced users.
Integrated Power Supply Module with USB Connectivity
The kit includes a breadboard power supply module that provides stable voltage output for circuit operation. One of its key advantages is the inclusion of a USB power cable, which makes it easy to power circuits directly from common USB sources.
