Next week, I am going to buy a Raspberry Pi 3 and I want to buy a mouse and a keyboard with the Pi.
Can anybody please tell me if the Logitech MK235 works with the Raspberry Pi?
Really this is mostly an operating system issue, and not a brand-of-my-computer issue. Presuming you are using Raspbian or some other GNU/Linux variant, the OS kernel (which is what implements hardware drivers) is one which is used on tens of millions of normal workstations and laptops.
That looks like a pretty standard wireless keyboard/mouse combo ("Fullsize, durable, simple"). USB HID (human interface device) protocols are standardized, and anything like that will be fine. There's only a potential issue when you get into zany mice with 42 buttons and lots of special features that require a proprietary driver. That Logitech product does not fall into such a category. I've used piles of Logitech HID ware with linux over the years including wireless keyboard/mouse combos.
In other words yes, I promise it will work with the Pi 3.
Note that by default Raspbian uses a UK keyboard layout. Because of this you will notice a few keys don't print what they are supposed to. To fix this, when you first turn the Pi on, you should be presented with a program called
raspi-config which lets you set various options (if not, just run
sudo raspi-config at the command line). The fourth option of the main menu should be "Localisation Options". Choose that, then "Change Keyboard Layout" and select a US 104 key PC keyboard.
While attempting to use the MK 360 combo with my rPi Zero W I have discovered that: -- if the receiver is attached directly via OTG Cable both the keyboard and mouse work no matter what -- however, if I connect the receiver through a cheapie 4-port USB hub (with power), I have to have both the keyboard and mouse powered up before booting the rPi Zero W. -- upon boot and verification that the combo is working, I can switch power off on the mouse and keyboard and everything works fine if I power up the combo at a later time So maybe if a particular Logitech (or any brand for that matter) Wireless keyboard, mouse, or combo is playing tricks with you, see if following the above pattern helps...
