What is there to say, it's a Micro USB-B female socket connector ready to add to your latest invention.
This is a surface mount device, note that these are Micro-B the pin pitch is pretty tight if you're hand soldering (or etching your own PCB, it's getting down to the need-a-factory-made-board levels here), a very fine iron tip, flux, a steady hand, and probably some magnification may be necessary.
I also sell Mini-B sockets.
All of our products are shipped from Christchurch, New Zealand using CourierPost for NZ, and Airmail for international.
