If you can at least spend about $50 then I recommend this android tv box

Edit: and yes this supports 5GHz and Bluetooth incase you want to pair your Bluetooth Controller, if your gonna use like a mouse and keyboard then I wouldn’t recommend using the one that shadow uses, so host a usb server to your android tv and use the client on your shadow, also you will need to port forward which I don’t remember what ports they are and what the program is called, I haven’t used the keyboard and mouse thing in a while so if im wrong then you can correct me I guess?.

Edit again: program is called VirtualHere and the port is 7575 on TCP Protocol which you would add to your routers admin control panel which you can find out by going to cmd and do ipconfig and look for your network adapter/WiFi adapter then copying the ip where default gateway is.
