Rubber Ducky??

I recently found out this thing called a USB Rubber Ducky. It basically emulates a keyboard and you can program the little usb stick to drop payloads or execute (malicious) commands.

The rubber ducky is expensive, like, 44 bucks, so I was looking for a DIY version, when I stumbled upon this:

So I thought of the Adafruit feather 32u4 adalogger, a 32u4 microcontroller with an sd card slot. Will this board be ok as a rubber ducky? I mean it's 32u4 so it can definitlety emulate a keyboard and the SD card means you can store multiple payloads at once.
