I am involved in a project where we will be doing a run of about 200 products. We do not know where in the world our client will be sending these products.
Each product uses mostly off the shelf electronics:
12V power supply (taking mains power)
The only piece of custom hardware is a simple transistor circuit for each arcade button to turn on the LED.
My concern for the project, is the red tape when taking the project to different countries. What kind of certification would I need?
