If you don't already have the Arduino IDE on your computer, download and install it. Place the USB Mini Host on top of the Arduino - the pins match up exactly - and solder it in place. Solder the pins in place on the underside of the board. You may want to angle these out a bit so they're easier to slide connectors on once you have the USB Host in place.

It might be nice to be able to access them once your project is complete, so put headers in them with the long ends sticking up. The six pins on the short edge are for programming. These will go into your perfboard when you build the complete circuit. Insert some 0.1" male breakaway header (some came with my USB Host, but if you've bought any electronics kit in the past you probably have piles of it) through the top side of the pin holes along the long edges of the Arduino, so that the long ends of the pins stick down through the board. My 5V wire was in the way, so Host got to be on top. The USB Host can sit on top of the Arduino or vice versa.

Now you can provide 5V directly to the USB port, and the USB Mini Host will keep the 3.3V to itself. Solder wick or sucker would probably have been less careless, but things still worked for me afterward. I failed at this - too much solder maybe - but I was able to fix the short by scoring between the shield and wire with the hobby knife. Try to avoid shorting the pad to the USB jack shield. Check that there is no connection across the jumper using your trusty multimeter. Be careful you don't cut anything else important - it takes less force than you probably think. Fortunately, Mazurov made it possible to provide 5V to the USB port fairly easily.įirst, use a hobby knife to cut the VBUS jumper, shown in the image above. I assume other devices will work too however, the wireless dongle for the keytar would not. My MPK mini mkII seems to work fine on this voltage - as you can see in the pics the panel buttons are just a bit dimmer. Out of the box, the USB Mini Host will provide this 3.3V to the VCC pin of the USB port.

The USB Mini Host and Arduino Pro Mini both run on 3.3V. You may also want a more permanent enclosure - I used a small cardboard box something else came in because I was in a hurry to use this at a gig (video evidence above) and it looks punk. I find this one very useful for the separated pins.įor power you'll need a source of 5 Volts - a phone charger with a USB A to B cable will do, or a computer USB port.
