USB to microUSB OTG Converter Shim

This is the kind of seat-of-the-pants engineering genius that you only find in hackspaces, garden sheds or Shenzhen.

It's not for the faint-of-heart, it's not particularly spec-friendly, but it is useful and cool for Pi Zero hackers!

This tiny little shim pushes inside a full-sized USB connector and transforms it into a USB-On-The-Go compatible microUSB connector.

It's perfect for plugging a single USB peripheral into the Pi Zero with the minimum amount of spaghetti wiring.

Note: Plug into your USB device first, making sure the four contacts are facing in towards the contacts inside the USB connector! It's on you if you put it in the wrong way and things go FZZZZT! :D

Warning: You should also never plug this into a USB-A receptacle 'female' port, only a USB plug 'male' style device. So don't go plugging the big end into your Pi 3's ports :-)

It worked, fast shipping and great quality ( Please be aware though that it is quite tight so you need to be able to take it out with ease) thank you

This is an amazing gadget - whoever realised that you could make an OTG convertor this small needs so much praise and recognition piled on them (and maybe a vast pile of money too). It's so conveniently tiny, and easy to use. I need more!

This is a nice little adapter that can be easily used with the Pi Zero. Low profile and easy to use (just make sure you insert it the right way)
