Not directly related to agopengps but what would be a good gps chip for a speed only application? What I have in mind is something similar to an F9P or um980 dev board but cheaper. I don’t need high absolute position accuracy just decent accuracy for speed. I was thinking .1 to .2 mph (.16-.32 KPH) error would work. Just something I can used to generate a speed pulse signal for some older rate controllers when they are not hooked to any other GPS.
if it is only Speed no need so advanced GPS speed
a basic one can do the task
after an arduino to catch the GPS speed and transfert the pulse by Tone function can be enouth

That’s a better price on a prebuilt one than I remember. Wonder how well those last. I have had two similar products and they never lasted that long.
