The USB Host Shield Mini from Circuits@Home, is a compact version of the well known USB Host Shield that we have been using for a lot of our USB Host development on the Arduino.
The mini version makes it possible to add the USB Host functionality to Arduino Pro Mini projects by stacking the board on top of the Arduino. And the board is of course compatible to the USB Host library that we have added a lot of features to, such as PS3 and PS4 controlling.

This shield only work with Arduino Pro Mini boards, running at 3.3V-only. Due to the small form factor and pinout, the board can also be used as a MAX3421E USB Host breakout board.

This shield is shipped without headers by deafult. In the dropdown list below you can decide to get the board shipped with pre-cut matching headers.

Remember to visit the Circuits@Home blog with updates to the library, including new features and device classes: http://www.circuitsathome.com/category/mcu/arduino/usb-shield
Please also remember to visit the 'USB' category of our blog where we have posted many different guides and tutorials on how to use our contributions to the library, including PS3 controller, PS4 controller, Xbox controller and Bluetooth enabled devices (SPP, PS3, Wii, etc.): USB Host Shield blog posts Bluetooth specific blog posts
