What is it?

This is a BGA PCB, allowing free use of any supermarket trolley. Trollies are locked all together, which make them very hard to use with bicoins. This is the first electronic circuit every allowing you to hack and use freely trolleys!

It doesn't need battery, it doesn't need extra components! Amazing! Just insert the circuit inside the trolley lock. Wait for the magic, within a second, the trolley will unlock.

As you can imagine, this is the result of years of reverse engineering. This adapter will only work in eurozone, but if requiered, I can adapt it to other zones too.

This board is also much lighter than the orginial unlocking licence system. When using this adapter, your trolley will be slightly lighter, so inertia, more control. This will make the difference on race.

Why did you make it?

Because I can and because business cards are boring.

What makes it special?

This is special because it's new high tech system to hack an old low tech system. This is retro-engineering!

If you need BGA adaptation to you own company footprint, and change some other details, feel free to contact me.
