Why Parents Choose Tinkolo
Built for Curious Minds
These are engineering kits, not toys. Every project on this site is built around a genuine Arduino-compatible or ESP32 controller, with real sensors, real wiring and real code — the same parts an adult would use.
We are a retailer: we choose the kits, check what is in the box against the manufacturer’s own specification, and write the listing from it. Each kit comes with the maker’s illustrated, step-by-step booklet. Whether your child is 8 or 15, they build something that actually works.

How It Works
From Box to Bot in 3 Steps
1. Unbox & Organize
Every component is labeled and sorted. Lay out the parts using the checklist in the manufacturer’s booklet.
2. Build & Wire
Follow the step-by-step assembly guide. No soldering needed — everything connects with plug-and-play connectors.
3. Code & Play
Upload the starter code, then customize it. Make your creation walk, sense, blink, and respond to the world around it.
Our Mission
Engineering Skills Start With Play
Every child deserves the chance to build something real. We choose STEM kits that bridge the gap between play and engineering — kits with the confidence-building payoff of a project that runs at the end. They are not simplified toys. They are real projects, built from real components, that teach real skills.
Frequently Asked Questions
What age are these kits designed for?
Each kit carries its own age grade, printed on its product page. The Smart Farm, Smart Home and Biped Robot kits are graded ages 8 and up. The Weather Station and the Bionic Spider are graded ages 10 and up, because the assembly is finer and the build is longer.
All of them contain small parts and are not suitable for children under 8.
Do I need any prior coding or electronics experience?
Not at all! Every kit includes step-by-step illustrated guides that assume zero prior knowledge. We walk through every wire connection, every line of code, and every assembly step. Parents and kids can learn together.
What tools or batteries are needed?
No soldering, ever — every connection is a breadboard, a jumper wire or a plug-in connector. Each kit lists its exact contents on its product page.
You supply a computer with a USB port to upload the code. The Biped Robot and the Bionic Spider also need 4 x AA batteries, which are not included; the Smart Farm, Smart Home and Weather Station run from USB power.
How long does it take to build a kit?
Build times come from the manufacturer of each kit: Smart Farm, Smart Home and Biped Robot are 3 to 5 hours, the Weather Station is 3 to 4 hours, and the Bionic Spider is 4 to 6 hours. Most families spread that across a weekend rather than doing it in one sitting.
What is your return policy?
You have 30 days from delivery. An unopened kit can go back for a full refund, and we pay the return shipping.
If a kit arrives faulty or damaged, or a part is missing, tell us within 7 days and we will replace it or refund you in full — there is no need to return an opened kit for a missing part. Our Return & Refund Policy has the detail.
Do you ship internationally?
We offer free shipping on every order within the United States — no minimum purchase required. Standard delivery takes 5-7 business days, and express shipping options are available at checkout.
