Why RoboSemi
Built by engineers.
Trusted by makers.
We actually test this stuff.
Before any component goes on our site, someone in our Purnia lab has plugged it into an Arduino, probed it with an oscilloscope, and confirmed it behaves the way the datasheet says. We've turned back entire supplier batches because they didn't. That's not a policy — it's just how we'd want to be treated as buyers.
Oscilloscope · Logic analyser · Integration checks on every new SKU
An engineer reads your message.
Not a chatbot. Not a ticket queue. When you WhatsApp or email us, the reply comes from someone who has actually debugged an I²C hang at 2 AM and knows exactly what you're going through. We review schematics, suggest swaps, and write example code — because that's the kind of support we wish had existed when we were starting out.

Dead on arrival? One message fixes it.
Send a short video of the issue and we'll dispatch a replacement within 48 hours. We don't have a "warranty department" — we have people who know how it feels to sit with a dead component and a project due tomorrow. Returns get resolved in one conversation, not a form, not a queue.
DOA swap in 48 hr · 7-day returns · 6-month defect warranty
Also worth knowing —
Same-day dispatch
Order before 3 PM and it ships today. Not a premium — the default.
Packed like it matters
Anti-static bags for ICs, bubble wrap for boards. Not an envelope.
Real stock numbers
If it says 'in stock', it's in our warehouse — not at a vendor 400 km away.
We ship everywhere
28 states including places most couriers give up on — Andaman, NE India, Ladakh.
Bulk without the portal
BoM sourcing, net-30 terms, custom packaging. One conversation gets it done.
Knowledge with the component
200+ free tutorials, YouTube guides, Discord — context comes included.
