G12S Amlogic S905X2 Android TV Box Comes with 2T2R WiFi 5 Connectivity

Several Amlogic S905X2 TV boxes running Android have launched with products such as X96 MaxBeelink GT1 Mini, H96 Max X2, or Mecool KM9. Some of those boxes come with WiFi 802.11 b/g/n, and others feature better  WiFI 802.11ac (WiFi 5), but according to ACEMAX no model comes with a 2T2R (2 transmit / 2 receiver) antenna setup (aka 2×2 MIMO) except for their G12S TV box sold on Aliexpress for $55.99.

So if you aim for the best WiFi throughput possible in your TV box, it might be worth having a go. ACEMAX normally adds their brand on OEM product, and the actual manufacturer should be ShiningWorth with the G12x2 model.

On the Acemax website this product is listed as K12 with similar specs but a different logo.

Guess we’ll see that appear elsewhere.

Seems a nice device though with value for money. Not sure how good their 2×2 solution. It would also be interesting to know what WiFi solution they use.
