Frequently asked questions
1. How do I know if I need bespoke electronics design services?
You need bespoke electronics design services if...

Your device:
  • does not have existing analogues
  • there are analogues, but they are not suitable due to functionality
  • there are foreign analogues, but you require local ones
Your company:
  • does not have in-house design department
  • has a design department but it is overworked
  • has a design department, but it needs more certain competences
2. How much do you cost?
It depends on many factors: functionality of the device, its anticipated amount of production, need for integration with orther systems etc.

We will give you our estimates as soon as we understand your task. We will calculate a precise time frame and cost of each stage after the Terms of Reference are approved.
3. How long will it take to design my device?
See the answer to the prevous question.
