Can I use a Rf receiver with the arduino?

I am working on a personal project with an arduino uno. I have a wireless keyboard and mouse that uses Rf signals to communicate with with the USB type A receiver. Apparently the USB host shield has been retired and I cannot find another way to connect the receiver to the arduino. So I was wondering, can I get a Rf receiver module (without performing surgery on the one I already have), connect it to the the wireless keyboard and mouse, and wire it to the arduino? If it cannot be powered by the arduino, then I can power it another way. Also I will use a 9 volt battery to power the arduino so there should be a few spare volts.

You might be able to get it to work with an OTG adapter and a board that has a native USB port. The M0, for example, can actually read a keyboard. I was playing around with keyboarding on the Due last night. (I’m going to build a mini dumb terminal using the Due and an LCD module.)

There are other options, though: you could use a serial keypad, which should allow you to hook up using a MAX232. You could also use a PS/2 keyboard, which has a low enough signaling rate and works at TTL levels. You could use a Tandy TRS80 model 100 as a serial terminal… (I used to use one to remotely control Winamp from another room…)

You could also use something like an APC220 radio module; Amazon sells a kit with a USB adapter and two radios; you connect the USB adapter to your PC, then use a terminal program to talk through the wireless link.

Apparently the USB host shield has been retired and I cannot find another way to connect the receiver to the arduino.

Perhaps you should try Googling “Arduino usb host shield”?

It is retired on the official website and I don't know which one is good on amazon because I didn't see any from arduino.org. That is the company name on amazon.

IMO, Amazon is a more expensive version of eBay. Same stuff, it just costs more.

Just because Arduino retired the product doesn't mean you cannot buy one. Digikey has 26 pieces in stock, $26.40 each. Sparkfun also manufacturers USB Host shields, $24.95.

Thank you. I might end up buying the one from sparkfum, but first I might figure out if I can just by a single rf receiver.

Just buy a host shield. You have no way of figuring out the RF frequency, modulation method or software protocol. Trying to create your own receiver is complete waste of time, it’s simply not a realistic possibility.
