Hi I’m looking into GPS modules and came across the SUP500F (provided by SFE) and the ST22 ([data sheet) which both use SKYTRAQ’S Venus634flpx chips. Now I can’t find any differences between them apart from the price (the SUP500F claims -161dBm sensitivity as opposed to -160dbm but I presume that is rounding by looking at the other specs given).
Has anyone used either of these or know the difference between them (if there are any differences!)?
Cheers,
Mark
