How to connect Nexus 7 to a keyboard and a mouse
Why do you want to connect Nexus 7 to a keyboard and a mouse? Make a tablet as a “computer” but 7-inch tablet could be a bit small for its screen size.
My daughter recently broke the screen of our Nexus 7 2012 so the touch screen doesn’t work anymore. I was debating to get a LCD Touch Screen Digitizer Assembly Replacement for ASUS Google Nexus 7 Tool OEM for $50 or just retire it?
It happens I have $50 microsoft store promo code lying around. I went ahead to use it and one of items I ordered is StarTech Micro USB Male USB Female OTG Host Cable Adapter. It costs $8. I connected its micro USB male to the broken Nexus 7 and a USB receiver for HP Z4000 wireless mouse to the other end. Instantly the mouse is working on Nexus 7 and I could navigate around. However, the on screen keyboard doesn’t pop up when I want to enter texts. It looks like it is required wireless combo (keyboard + mouse) to work. The budget Logitech Wireless combo (MK270) costs around $30.
I tried with Logitech MX518 optical mouse that has USB interface and I could see on screen keyboard pop up when I want to enter texts. If you have an USB hub lying around, you could connect USB keyboard and mouse to the USB hub. Then connect USB hub to the adapter. That should work, too.
