Plug-and-play IoT components,
tested in real builds.
Hardware for makers and small teams — sensors, dev boards, displays, relays, wireless modules, and more. Designed, tested, and documented by engineers who use the same parts in their own builds. Trusted by 5,000+ builders worldwide.
How ShillehTek Works
The flywheel: build it, document it, sell it.
Every product on this site started as a part Mahmood needed for his own engineering work. The tutorial came next. Then the component went on the store — tested and ready for the next builder.
1. We build with it
Real prototypes, real consulting projects, real production deployments using each part.
2. We document it
Free YouTube tutorials and written guides covering wiring, code, and pitfalls — by the engineer who built it.
3. We sell it
Tested, ready to use, and shipped same-day from our US warehouse — backed by the tutorial that walks you through it.
Every product was built with first.
What We Do
Three things, one mission.
Components are the core. Tutorials and consulting are how we earn the trust to sell them.
IoT components & modules
200+ sensors, dev boards, displays, relays, motors, wireless modules, and connectors — tested before they ship and sent same-day from our US warehouse. Compatible with Arduino, Raspberry Pi, ESP32, and STM32.

Talk to usWhy ShillehTek
Four reasons to buy from us instead.
We're not the cheapest. We're the most reliable place to get components that actually work the first time.
Tested before it ships
Every module is checked against the same wiring and code we publish in our tutorials. Many parts come pre-soldered and ready to plug in.
Same-day US shipping
Order by 3pm ET, ships from our US warehouse the same day. No 3-week Aliexpress wait.
Engineer-led, not dropshipped
Every part is one we use. If something doesn't work, we know — and fix it — because we use it too.
Free tutorials by us
Stuck on wiring or code? The same engineer who shipped the part has a tutorial showing exactly how it's used.

Founder & Engineer
Mahmood Mustafa Youssef Shilleh
Mechanical Engineering · MS Computer Science
I started ShillehTek in 2022 after years of frustration: I needed reliable components for my embedded projects and clear tutorials I could trust, and neither was easy to find. So I built both.
Every product on this site is one I use myself — in my own builds, in tutorials I publish on YouTube, and in IoT consulting work I do for startups and small teams. From early sensor kits to enterprise-grade deployments, I stay close to the code and even closer to the community of builders.
Our Story
Built in the lab. Now powering real systems.
From a one-engineer side project to a small team shipping components and consulting worldwide.
Founded ShillehTek
Started to bridge the gap between beginner-friendly IoT kits and real project support.
Sensor kits + free tutorials
Launched the first sensor modules and breakouts alongside YouTube tutorials. Community grew to 5,000+ builders.
Grew into IoT consulting
Started taking on prototyping and embedded systems work for startups and educators.
Full-stack production builds
Now offering production-ready firmware, cloud, dashboards, and deployment support.
What customers say
4.7★ from 914 verified reviews.
A few recent ones — and yes, those are the actual numbers.
The relays arrived ready to go and worked first try with my Pi. Mahmood's tutorial walked me through the wiring perfectly — bought from him because of that channel.
Bought 10 ESP32 modules for a small batch. All tested and labeled. Saved me hours and one bad cap. Will buy again.
Same-day shipping in the US is huge. Got my order in 2 days. The breadboard PSU works exactly like in his video.
