Hmmm, I wonder if Ardusimple has been reading this thread? They have recently released a whole line of UM98x based boards. 
They have a nice configuration page. Look at the bottom of the page for a nice bonus.

Possibility… Yes, but prices are far from competitive.
Definitely. I’ll keep using the UM982 boards from Ali for $105.
That firmware (the lastest mentioned in the command reference manual) was given to me by Witmotion 1 month ago, when I bought the board, but the problem is that if you check the binary, the date of compilation is december of 2023 for that 11826 build. It should be available a more recent one, that’s why I asked here if somebody succeded in contacting Unicore.
Not sure what their release cadence is like. uBlox goes for a year or more sometimes between publicly released updates.
The funny part is how they don’t put in their servers the latest version of the Uprecise software. Maybe because this was updated 1 week ago?
The latest version for um980 is 11833, for f9p it is 1.50, for um982, if I’m not mistaken, 11826.
Which TTL module should be used for UM982 ?
I have the PL2303 module, but it doesn’t work.
The ones I use are based on the CH340B chip.
