Folks: I’ve been doing a lot of SW work using the U-blox ZED-F9P chip over the past few months. Being a SW guy, I try to minimize the amount of breadboarding and HW integration I have to do. For several months most of my work has been using the SimpleRTK2B board from Ardusimple in Barcelona Spain: US$193 plus shipping. https://www.ardusimple.com/simplertk2b/ However, recently I noticed that SparkFun just up the road from me in Boulder Colorado has a GPS-RTK2 board with a F9P: $220 plus shipping. https://www.sparkfun.com/products/15136 The GPS-RTK2 is little more than the SimpleRTK2B, with different additional capabilities. Since ultimately all I needed was the USB connection for my SW hosted on a Raspberry Pi, the SparkFun board worked with my SW with zero changes or drama. :John -- J. L.

Hi There was a lot of discussion on the Sparkfun F9P board about six months ago. Since then uBlox came out with their own board for the F9P. Like the Sparkfun board and the bare F9P modules it shows up at Digikey “most of the time”. For whatever reason, they go in and out of stock (which is understandable) and also go in and out of “obsolete” (which is a bit harder to follow). The uBlox C099-F9P https://www.digikey.com/products/en/rf-if-and-rfid/rf-evaluation-and-development-kits-boards/859?k=F9P <https://www.digikey.com/products/en/rf-if-and-rfid/rf-evaluation-and-development-kits-boards/859?k=F9P> Seems to be the best option in terms of “bang for the buck”. It’s slightly more expensive. It does come with an antenna and a bunch of interesting bits and pieces on the board. Indeed if none of that is of any use to you, the other boards are indeed cheaper.
