The Real Deal When the world of Arduino was shown to me a few weeks ago, I was intrigued. After watching some Youtube videos, and reading online accounts, it became clear that the use of Arduino with various sensors could do some amazing things. The hidden "mad scientist" within me started to come out.Looking thru the Amazon reviews showed great ratings, BUT there were a few issues that popped up in some reviews. Some indicated that they received fake Arduinos. A few said there were some quality issues.Issue 1 - Fake Arduino? An online post suggested that the Amazon seller be cross checked with "approved" vendors as listed on the official Arduino web site. I purchased mine through Karlsson Robotics, and they are indicated as an approved Arduino "supplier". The first thing I did when receiving my Arduino is to check all the standards means of detecting a fake. Every item checked out, in particular the gold 504L device. I am 100% assured that this is a product from the factory in Italy.Issue 2 - Quality? The quality of the board, solder joints and devices appears to be just about perfect. There are no instances of incomplete or rough solder joints. Everything is soldered in a super smooth manner, probably from one of their production machines. It's an outstanding job. So far I've done a few operations with the board, and no issues have been observed. The board connected easily to the computer via an A-B USB cable (not included with the board).Bottom Line:Karlsson Robotics is a legit supplier, and they provided my Arduino board with zero issues. Highly recommended that you purchase though them. The Arduino board is top notch, and is ready to go out of the box. 5Terrific - And it's expandable in many ways. POWER my world. Great device. I bought 3 of these and they are my go-to controller for some pretty sophisticated DIY projects. Do read about how not to over-drive the pins (demanding too much current from them). And, DO read about the difference in the +5v and "Vin" pins. There is a company that sells just the processor chip. They are reasonable (pkg 3) and I recommend having them on hand in case Murphy stops by for a visit. If you follow basic principles and NEVER try connecting a pin to something for "trial & error" but instead, be certain of the voltage AND current potential that you are supplying (or demanding), and this beautiful device will work like a horse. When it comes to your connection to the computer, some Windows serial "portage" issues arise but it's a matter of persistence. The Arduino IDE (programmer) has ways to let you see how things are going and which PORTs are connected and working. This is the only part that can be frustrating (other than writing software bugs. :-) Enjoy.. here's what I think about it and how I use it this week:Have fun:Keep in mind that if your project is complex and you need more pins, you can use the nice I2c bus that this UNO has available and you can connect Slave devices to expand the "pin-age". :-) I am going to add a AdaFruit Trinket Pro (powered from this UNO 5v bus) and let these two guys talk to each other over I2c; exchange info, and I get tons more PWMs and digital pins too. The cool thing is that the Trinket fits right on the back of this UNO's added shield. SWEET !!As usual, these are great. Notice that this is the R3 -- exactly what you want. I've written some great control software for controlling the RF oscillator in radio transmitters and this made the project a success. I added a stacking shield (Gikfun Prototype) for the additional hardware I needed and this UNO allows the flexibility of updating my own sketches if a new feature in my RF unit is warranted. 5It's not what I thought but it's a good board I purchased this with the impression it was an authentic Uno. At unboxing I thought this was a well disguised knockoff. It's a different color, the silkscreen is different, etc. This is NOT an authentic Uno provided by arduino.cc. However, it does appear to be an authentic Uno provided by arduino.org. You are not contributing to the cause when buying this board. I wanted to give the seller 2 stars but after reviewing his ad again I realized he delivered exactly what he said he would. I got what I paid for.The build quality is in par with the blue .cc arduino and better than some knockoffs I have. Mine came with a nice plastic base to keep your bottom leads off the work surface so that's a plus. I haven't powered it up yet but I doubt I'll have any issues.I will note that you should have at least one socketed version. Many Uno clones are surface mount 328P's. If you don't have one or you are looking for your first Uno this isn't a bad one to have. I bought this one with the intent to program the Atmel and remove it for a project.Enjoy 5Going to great lengths to appear genuine This board works well and has the distinct advantage of having the ATMEL chip socketed. But, his board was a knock off copy of a real Arduino UNO R3 board and since these are open source boards, that shouldn't matter. What does matter to me is the fact that the manufacturer of this board decided to print "made in Italy" on the board and do everything possible to make this look like the genuine article. There are several manufacturers of Arduino "clones" (Like Sunfounder or SainSmart) that don't attempt to look like the original and don't attempt to deceive unsuspecting customers. Since Arduino provides it compilers, program examples and circuit diagrams for free, lets at least try to support them and if you choose not to, then purchasing a clone is just fine. Trying to pass a clone off as a "real" Arduino is just silly. 3Counterfeit board. DO NOT BUY!!! Board is clearly counterfeit when compared against the official ones on arduino.cc. They have a section for identifying counterfeit boards, and this board is junk. While I understand that arduino is an open source thing, printing arduino.cc on the back (to look official) and delivering substandard parts is bullcrap. I paid a premium for the official board, and it was NOT delivered. Things to note in the photographs: The "A" in arduino is filled in, the font (especially the "O") in Uno is different, and Italy has no detail to it. All are pointing to an inferior product, and being counterfeit by the official site. 1Authentic Arduino Uno I received this Arduino Uno from MDN USA. This Arduino Uno is authentic. It is the new design (teal color). All silk screening is spot on and has quality components. The difference from traditional authentic Arduino Uno (which I have and is green/blue color mixture from Arduino.cc) is silk screening on header pins for easy identification when using shields, which is high quality screening. The header pin silk screening is value added in my opinion (see last sentence to know more). In addition, the Arduino Uno comes with a clear plastic base (quality) for the board to rest on surfaces without accidentally grounding/shorting pins on bottom of board. The clear plastic base has two screw holes for securely mounting to surface. The Arduino Uno board clicks into clear plastic base and is easy to remove without releasing unintentionally (i.e. positive hold). This Arduino Uno is derived from Arduino.org instead of Arduino.cc, which is splitting hairs and not going to elaborate. 5Beware which seller you buy from! Bought 2 of these a couple months apart.First from MP3 Car Store was a genuine Arduino that has worked beautifully. Arrived in original packaging with a plastic sled to clip into.The second was from Pro Tech Trader. This one was counterfeit. Arrived in a static bag. It failed every test from:[...]Returning immediately. If I wanted a knockoff, I could have paid knockoff price.5 stars for the original, 1 for the fake. 3"Beware Mine Im Sure Is A Fake" from Mp3Car Store jan 2015 I ordered this board on 12 Jan 2015 And when was shocked to see the way it was wrapped and packed board had no packing just crudely wrapped in cardboard thin like cereal box no writing on it then shoved into a crazy low budget box which was crushed and ripped open it came with no original packaging at all no instruction booklet warranty paper nothing at all only Amazon paperwork on outside of box.. Then I inspected the board and straight away it looks like a bad fake the was it's printed looks bad dull colours and the words arduino are of alternating ink thicknesses and the O in arduino is oblong shape not a proper circle like the original also the headers and dc input are soldered on angles not straight and the USB Port has rust on the side and underneath also usually it says reset on the board under the reset button this one has no writing at all also the two circular components behind the dc input are two circular (power caps I think?) rated 25v on the originals there 16v. Soldering seems ok there's one pin with too much solder on It,And it just looks fake when I look at picks of the original I'm like no way mines definitely a fake but it works fine I've had no problems at all I hate not getting the original box and papers to go with it and the bad way mine was packed just cements my thoughts on it been a fake Chinese knock off and what really got me mad was I used the 1 click buy system I bought this board and the book programming arduino both were approx 28 dollars total well I paid 29 dollars shipping but with conversion to Aussie dollars it came to 70 something dollars omg what a rip-off I didn't realise I paid more for delivery than the products were worth Aaargh! Il try to upload some pick to support my claims but I can't see no option to import or upload a picture I'm on galaxy s5 Amazon appAnyway I'm sure mines a fake even though the invoice I got from MP3Car sales states. . Its/Genuine Made in Italy Arduino Uno R3 (Official Authorized Arduino Distributor)So just Beware mine does work though just looks like it's been at the pub all night got into a few fights shirt ripped black eye etc slept in a dirty skip bin, got home 24hrs later only to find his wife has left him and is dating someone else lol 1Arduino UNO R3 is a cool micro-PLC This is a micro-PLC. (Programmable logic controller). The setup () loop does first time execution. the loop() does continual scanning of Inputs and writing outputs. I'm an electrical engineer and control systems engineer, and I was enjoying learning to program the arduino as an embedded controller (PLC). The arduino.org arduino is a spec product (same as other Chinese knockoffs, but as long as they meet spec, they are a hammer...just not with the same namebrand). If you look on the web, arduino.cc is the Italian webpage with rights...but arduino s.r.l. also says that they have rights. it is confusing. the software from arduino.org for the ARDUINO IDE (The programming environment to make arduino code, to compile it, and to push it to the controller) is software revision 1.7.5. When you load it, it says that it is a modified version of the arduino.cc software. this is messed up, as arduino.cc has version 1.6.5. I found it suspect after installing the .org software so I uninstalled, ran a virus scan, and installed the .cc software. (.cc software will work on any arduino that meets the arduino specification).All in all it is a cool product. for intro to programming, it gives quick results. if you are a control systems engineer like me, then you have a $25-ish PLC that you can make to do any amount of awesomeness (provided that you use the 14 digital In/outs and 6 analogs to accomplish said awesomeness). Tomorrow night I get to work on using add-on cards.Word of advice: D13 is internally connected to an LED with inline resistor on the board. You don't need any extra stuff (LEDS, resistors, etc) in order to do a first program to make the D13 an output and toggle it high and low, and feel good that the board works. Similarly, a blinking D13 can prove that a program is running when it blinks on at the beginning of the loop() function and off in the midst of the loop() function. Word to the wise. 5I spotted many solder (some good, some questionable) repairs I ordered four for prototyping, and not for permanent use. The price was a fit for these "Refurbished" units, not brand new off the line. All of them had an offset (not straight) power barrel. I spotted many solder (some good, some questionable) repairs, and an off center crystal on a couple. There are fingerprints all over mine, not a biggy. I checked each one with a volt meter, and a sketch with an 7 Segment Display counter. They work fine for the prototyping. But I would not count on putting them into a permanent application. If you're on a budget, and need them without documentation. Prepare to check it over, including pressing the Amtel Chip into the socket for a proper fit. Then these are for you! Arguably, the seller should remark they are refurbished and may come only in a static bag with USB cable only and are shipped from China!! 2
