SXTsq Lite2, 500m, OrangePiZeroLTS as Access Point.

I need to establish network communication between OrangePiZeroLTS SBC and other device on maximum 500m distance. I found out that SXTsq Lite2 “propably” will be good enough to establish stable connection, but there are few problems: place is outdoor and has many natural objects like trees, probably will be quite crowded, there are other access points working in 2.4 Ghz and single board computer will be placed in moving vehicle.I can link mentioned place on Google Maps. Mentioned SBC have ability to work as an access point, but it’s gain(?) is comparable to Android phones access points. Network setup will be temporary - only for few ours. I don’t need high speed link between devices. OrangePi will only send diagnostic data from vehicle. Is this Mikrotik device proper to this job? Should i change it to something else?
