Remora - ethernet NVEM / EC300 / EC500 cnc board

Hi Guys, I'm pretty new here and just getting started with LinuxCNC, I've been retro fitting a rf31 mill and have a NVEM V2 I was using with Mach3 on an old laptop. the laptop started to play up and lost all my motor settings so i decided to ditch it all and buy a Raspberry Pi 5, load it with LinuxCNC and set it up solely for this machine.
I recently got my STlink all setup and now I need to confirm which bin file I need to download from GitHub? is it the Remora-NVEM-STM32-1.0.0.bin file in the Remora-NVEM/firmware directory or the Remora-NVEM.bin file in the Remora-NVEM/Remora-NVEM-STM32/Firmware directory? 
I'm going off the Scott 3D Youtube videos, but the GitHub info seems to be a bit out of date. Is any of the info in those videos still up to date or should I be looking elsewhere?
Thanks

is it for sure an STM32 board?

I believe so. 

just use the one here github.com/scottalford75/Remora-NVEM/tree/main/Firmware
use only the files in that repo for linuxcnc installation as well, the remora-nv one
everything in the videos about this stm board will still be relevant im sure


these stm ethernet boards have more users than i would have guessed

Thanks, much appreciated!
Yeah, the board was a pretty attractive option when I bought about 6 years ago.
