REXQualis Electronics Component Fun Kit w/Power Supply Module, Jumper Wire, 830 tie-Points Breadboard, Precision Potentiometer,Resistor Compatible with Arduino, Raspberry Pi, STM32

This is a great kit for the price. The only thing you're missing is an SBC or a micro controller (I'd recommend a Linux SBC for more flexibility if you're just starting out, the GPIO interface is going to give you full control without limitations like tiny memory, lack of disk space, or a slow CPU, most SBCs, even if cheap, can drive 1080p video streams without hiccups, they can handle a few GPIO attached devices without pausing). You'll need a controller device to use the kit but other than that it is fully loaded. I haven't tried the buzzer or the IC 4N35 but other than that I've tried all of the parts. Everything has worked great and as a starter kit it has had everything I needed to have fun and make some blinking lights controlled by software. The breadboard is standard and has those side plugs that let you attach it to more standard breadboards if you need something bigger. I like that the power supply has both USB and a barrel plug option. I've only used USB but the option is there. I like the USB power though, I have a ton of various USB-A chargers, but not any 5V barrel power supplies, (and my laptop could power it up via USB-A too, hell, the SBC probably could power this kit via USB-A on its own...).

UPDATE: I just realized that this kit comes with only two ICs. Not a problem for me because I have a stock pile of old ICs I've had for years. If you are new to breadboarding, you will want to get a mix of ICs, starting with a 555 timer. Amazon has a great selection of IC Kits, so pick one within your budget and have fun! This is a great little kit. I'm retired now, but I made my living for many years as an Electronics Tech, so I thought it would be fun to "play around" a little. This kit has plenty of bits and pieces to spend many hours just playing around, but I find the components are small for my clumsy hands and fading vision. I made a couple of projects and plan to make a few more, but eventually I'll have to pass it on to the younger generation. If you have a pre-teen or teen with an interest in this sort of thing, I happily recommend this kit.

I purchased the "REXQualis" component kit because I've been wanting to re-start an electronics hobby I had when much younger and needed a starting point to get my components/parts collection started again. I hadn't heard of the brand before and selected this item based only on the price and contents promised. Overall, this is a rather decent little beginner's kit. Most importantly, it offers a good-quality breadboard and power supply to begin with. The LEDs and buzzers provide a few little things to "play" with lighting up and making noise, while there's not so many solid-state & passive components to be overwhelming. Within a week or two I knew what additional items I wanted to purchase (or what I needed to build with) and was able to easily browse online (Amazon & others) to start adding to this collection. Many months later, now, and I have a huge stockpile of parts and tools. I love spending my spare time tinkering, building, and learning. This hobby is fun and very rewarding...kinda like working a puzzle, and for me it all started with the purchase of this little kit. The only little issues or complaints I have are minor. Mainly, there could be much better literature or online support offered. The web-site link provided leads to online pages that could have been organized and edited much better. I think the seller could have offered more along the lines of sample projects and info. behind the individual components. This is there...but only in limited ways. If you're a beginner, or wanting to start or add to a parts collection, then this kit is very good. It's been a great starting point for me. Just keep in mind, you may need to be a little resourceful online when looking for buildable project ideas.

This is an excellent starter kit. It's got lots of connectors and enough small components to make tons of test circuits. It even comes with it's own 3.3 and 5v power supply that plugs right into the breadboard. For the price, you can't beat it. The added buttons, switches, and other control components make very functional as a test board for building your own circuits. The included LEDs are low quality though... the white one burnt out within the first 10 minutes of testing. The rest have worked well so far.

Excellent components, all needed to start a project, the power supply works very good!

I just started learning about simple circuits and decided to build some. I had gone through Amazon adding all the components and parts I needed. The total was over $40, so I was extremely pleased to find this $16 product with everything I needed and more. On top of that, it’s all packaged nicely. There’s a big box for everything, and small components inside are either bagged and labeled or in a small plastic box. The jumper wires are bound with a small zip tie and the male/female wires are stuck together at the sides and easily pull apart. I’ve built a few circuits so far and they’ve all worked perfectly. They only thing id suggest buying in addition to this is some battery holders or another power source and an autoranging multimeter. The power supply module included is nice as well, just look it up online to figure out what cord plugs into it. You’ll also have to look on the manufacturers website to find the voltage and amperage for the LEDs. I know the white LEDs are 3.2-3.4V and all LEDs are 20mA.

I am surprised that such a variety of components and breadboard comes at such a reasonable price. All seem very good quality and I am looking forward to investigating the features.

breadboard was curved, hard to put a microprocessor. I started using it thinking it would work, but it did not work well. Bad build quality on the bread board.

Really great starter kit, or extras. Provides lots of variety of components, all the major sizes of resistors and capacitors that you might need. All the components are decent quality and well organized. It would've been nice if there were better specs or model numbers included for some of the components, especially on the LEDs. From my testing, the LEDs measure out approximately as follows: Yellow = 10mA @ 2.1v Red = 20mA @ 2.3v Blue = 20mA @ 3.2v Green = 20mA @ 3.5v White = 20mA @ 3.7v Since they are unmarked, I can't confirm the values are exactly correct, and your LEDs may be different than mine so YMMV. Be careful of the Yellow LEDs they are much more sensitive to higher voltages/currents than the other colors. I burned out several of mine.

Las compré para aprender y me han servido mucho.

I got it missing the following pieces: - 5 diode rectifiers - M/M usb cable - 20 ceramic capcitors - 1 Thermistor - 10 electrolytic capacitors - Active buzzer - Fiver transistors

Excelente producto, llego en tiempo y forma, muy bueno para diseño de circuitos

This kit is very useful and includes everything you need to start making circuits. I paired it with an Arduino Nano for prototyping and it works wonderfully. All of the components are high quality and they are all there. Best value for electronics starter kits.
