MT Intelligence
The domain has been registered for over two decades and is the globally recognized primary hub for the Arduino community. Our antivirus network shows a perfect clean record with zero flags from over 90 security engines. Technical data confirms the site is hosted on reputable infrastructure with a valid high-assurance SSL certificate. While some users report phishing emails or counterfeit boards from third-party marketplaces, these are external threats and not a reflection of the security of the official arduino.cc domain itself. The site is currently owned by a major global semiconductor company, further solidifying its legitimacy.
Web Research Findings
Our live research agent queries scam-report databases, consumer-review sites, news coverage, and general web search for arduino.cc, then cross-checks business-registration records and look-alike domain patterns. Everything below is pulled from what it actually found.
- arduino.cc is the official website of the Arduino open-source hardware and software platform, with domain age over 20 years (registered ~2005).
- Company: Arduino S.r.l. registered in Monza, Italy (VAT IT09755110963, REA MB-1910694); acquired by Qualcomm in October 2025.
- Wikipedia and all technical sites (Adafruit, GitHub, docs) direct users to arduino.cc for official boards, IDE downloads, and documentation.
- Trustpilot shows mixed rating (~3.5/5 from 17 reviews); Reddit has mostly positive user experiences with direct purchases and tutorials from the site.
- Discussions of scams/phishing typically involve fake emails, counterfeit boards sold by third parties, or unrelated sites; no widespread reports of malware or fraud directly from arduino.cc.
- Historical trademark dispute (2014-2017) between Arduino LLC (arduino.cc) and Arduino S.r.l. (then arduino.org); resolved with merger and later Qualcomm ownership.
- Arduino publishes guides on spotting counterfeit products and warns users about phishing attempts impersonating the company.

Still, stay alert
No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.
- Double-check the exact URL in your address bar
Confirm you are actually on arduino.cc and not a lookalike like a-rduino.cc.com or an IDN homoglyph.
- Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.
- OpenDiscuss this site on the forum

Safety FAQ
Common questions about this site, answered directly from the scan data above — so the answers always reflect the latest verdict on this page.
- Our automated security review found no threat indicators on arduino.cc. The site appears legitimate based on the signals we checked, but always stay alert for phishing emails that spoof real domains.
- arduino.cc passed our automated security checks with a trust score of 97/100. No antivirus engines or major blacklists flagged the site at the time of the last scan.
- Yes. arduino.cc presents a valid TLSv1.3 certificate issued by Amazon · Amazon RSA 2048 M01, expiring in 232 days. Note that SSL only encrypts the connection — it does not guarantee that the site itself is trustworthy.
- arduino.cc is 20.7 years old, registered on 10/26/2005 through MarkMonitor Inc.. Scam domains are often freshly registered — a site under 6 months old warrants extra caution.
- No. All 92 antivirus engines in our malware network report arduino.cc as clean.
- No. arduino.cc is not currently listed on the major browser blocklist feeds that modern browsers use.
- arduino.cc resolves to an IP operated by Amazon.com, Inc. in US (usage type: Content Delivery Network). Hosting location alone doesn't make a site good or bad, but unusual geography for a brand's claimed country is one of many signals we weigh.
- Yes. arduino.cc sits in the global top-100k on Cloudflare Radar, which means it has substantial real-world traffic. That does not automatically make it safe, but established brands almost always rank here and throwaway scam domains almost never do.
