About
CirkitLab is a small embedded lab. We design hardware and write software for devices that work in the field.
Why teams choose us
You talk directly to the engineer building your product, so nothing gets lost in between.
- 1 Board design fully checked and ready for manufacturing
- 2 Software tested on the real board from day one
- 3 You get all files, so any factory can build it
- 4 Clear pricing with weekly updates and test reports
- 5 Support after delivery if issues come up
How we work
Simple step-by-step work from your idea to a ready product.
- 1 We note your idea and needs like power, size and cost.
- 2 We design the circuit and board for the product.
- 3 We build the first sample and check it fully.
- 4 We write the software and test it on the real board.
- 5 We run final testing and hand over all files with factory support.

We built an automatic petrol to CNG changeover controller. It shifts the car to CNG 60 seconds after ignition.
Discuss similar buildIR + PIRLED Light SMPS
We designed the SMPS and PCB for ceiling LED lights, including IR remote and PIR motion versions.

Clients who shipped with us and have boards in the field.
We got our full starter range ready for sale. Timer, RTC and safety versions all held up in the field.
Our touch and remote panels worked the first time. Every size fit straight in.
They rebuilt our old meter on a new board and tested it fully. It matches the original.
The CNG changeover kicks in by itself after ignition. No manual switching needed.
Our SMPS and LED boards came out clean and stable. Both IR and PIR versions passed testing.
