I hate TP-Link! They use totally different chips in the same model. I have two externally identical TP-WN722N: one with Atheros, another with Broadcom.
So, check dmesg:
uftdi9: <FT232R USB UART> on usbus0
ugen0.26: <ATHEROS USB2.0 WLAN> at usbus0

Many times, cheap vendors change internals of devices, even the SoC device is based on and didn't mention it anywhere on packaging, device or documentation. So you have to check stickers, if there is some info about version, good for you, but absence of any related marking doesn't mean you have device first introduced under given name/type (AKA version 1).

AFAIK best resource for this problem are various Linux/embedded projects wikis, like https://wikidevi.com/wiki/TP-LINK_TL-WN821N_v1 or OpenWRT etc. Many devices have box and PCB markings, packaging etc. described, often with images described there.
