I was reading about the prospects of IoT and wan to start with it. So I want to buy a board. The 4 options are specified on the website. But there is this new board named C.H.I.P. I would like to know whether I can use this? If not, please guide which one is suitable to buy. Can someone please suggest a few resources from where I can learn?
Currently Windows 10 IoT Core only supports 4 boards:
You can see a comparison of the boards here: https://developer.microsoft.com/en-us/windows/iot/boardcomparison
I would suggest going with the Raspberry Pi 3 as it has built-in Wi-Fi and Bluetooth. You can purchase the board separately or get one of the many Starter Kits. The kit is a good option if you're just starting out. It will include the Raspberry Pi and many accessories to start learning and building projects.

Just remember that Windows 10 IoT Core requires a Class 10 microSD card. Some of the kits may have slower cards.
