Build my Own lightning adapter

[Metatron-technology]

I have a question about the lightning.

I want to build my own adapter (splitter Jack/Lightning), I want to use the lightning (charger) and the jack 3,5 mm in the same time.

Someone has an idea, how I can make it. (tutorial or information about...)

I Know that product exists but It's a personal project.

Thank's per advance

Lightning adapters and cables have an authentication chip. Some third party manufacturers clone it to sell their own adapters. Without it, you'll find after a short time(or right away), the adapter will be extremely fickle or not work at all.

You can get all the specs you need if you sign up as a peripheral developer. It’s not free but you’ll get all the specs you need under the “made for iPhone” developer program.

That said, the barrier to entry could be pretty steep, I haven’t looked in ages.

This should give you some insight:
