Wireless Card Choice

I have an Acer Aspire E5-475G and I was looking to replace the wireless card. But I don't know which card to use as a replacement.

The picture I attached is the card. Qualcomm Atheros QCA9377

Is this an E key or a half-sized A+E key? Is a half-sized A+E key even a thing, or is it a E key and I'm just dumb?
