I wonder what is the difference of cAP lite https://mikrotik.com/product/RBcAPL-2nD-307 vs cAP https://mikrotik.com/product/RBcAP2nD. Both are 2.4Ghz only, have same CPU und same size RAM.
While on paper they look pretty similar, disassembly would show otherwise. Both of them use a completely different PCB's and internal components. cAP version has metallic antennas with higher maximum gain.
The only truth from the speculations is that they have different physical designs. Where cAP-lite is actually much smaller or "slick".The manufacturers sometimes do that trick - create two identical things (say Lenovo x1 carbon and T4xxs series), one is a bit more slick and compact compared to another, then they charge more for the former. Suppose this is the case.
