If you dont need GPIO then you are probably better off looking at TV boxes or boards intended for that market instead of an SBC. That market is starting to see PCIe and USB3 attached 4x4 wifi chips and at very cheap prices. I brought back some dirt cheap RK3399 TV box boards back from China in June with AP6255 (2T2R) chips that perform much better than expected as an AP for upto 5-6 simultaneous clients. I get approx 425Mbps with 1 client, ~295Mbps with 3 clients and ~165Mbps with 6 clients. Tha
