UBLOX MAX-M8 series Driver Availability

[Gandalf_Sr]

I need to choose an updated GPS module for a design that currently uses an old Navsync CW25 GPS module.  The data needed is position, altitude, date, time, and 1PPS. I prefer the GNSS (multi-system) modules that are now available and I'm looking for advice on what the new module should be; requirements are for:

1. Ease of use (for me) which means drivers available that I can drop into a C code IDE
2. Runs off 3.3 volts
3. Supports an active (powered) antenna system

My existing system runs on the M0+ core of a PSoC 6 which communicates with the old module via UART and, initially, I'd like to drop in a replacement that uses the same (or close) UART Comms (so I can get it running quickly) but, in the medium term, the desire is to change over to I2C or SPI to talk to the new module, which I assume will have to involve some kind of proprietary Comms system (I'm not familiar with any of them).

I've been looking at the UBLOX MAX-M8 Series and there are drivers available for it on github here but they seem only to be for the serial Comms.  What would you guys reccomend (or not) as a module that meets my needs and are there any easy-to-use code downloads for the non-UART Comms?

Thanks in advance.

Not sure if it satisfies all your requirements but this is a nice and small GPS receiver: http://navspark.mybigcommerce.com/navspark-mini-6pcs-pack/.

the new modules from ublox seem to be quite popular, F9P and F9T (timing).
Not sure if they also managed to lower current consumption with the new generation of chips?
an active antenna might want +5V, not just 3V3.

most (all?) settings available through their u-center program are also adjustable on a low level through the UART.
