[time-nuts] Re: Is this a standard form factor for timing GPS?

[Daniel]

Thanks for the info. My plan was to buy one of these cheap LEA-M8T and 
design a board around it, knowing that I can later upgrade to a ZED-F9T 
just swapping the boards (and probably upgrading the firmware of the 
microcontroller that talks to it). Seems feasible? I'll dig the HUAWEI 
LEA-M8T pinout and see if it's compatible with the ZED-F9T...
