Cheap monitor mode mt7821 wifi dongle

[wtsh]

I found cheap MT7821 dongle with monitor mode on aliexpress. My adapter aliexpress link is broken

[MikeJSTB]

Is there an existing driver for it?

You can use driver for Hackergadgets wifi board. It uses same chip.

I used this board for quite a while with an USB adapter. Trixie detects it without any issues because it uses the same chipset, although it only has two antennas. Even so, it works really well.
