Your HEQ5 has newer rev C controll unit, that is installed in all HEQ5 made since 2019.
It uses newer (and quieter) TMC5130 stepper drivers as opposed to the rev B that used A3959 stepper drivers.
Rev C also has more powerfull STM32 controller.
The difference between firmwares is Rev B - FW: 2.x.xx
Rev C - FW 3.x.xx
The firmwares are not compatible between boards due to the HW being completely different.
Skywatcher website has both firmwares for rev b and c (or Version 2. Version 3.)
Hope this cleared things up for you

These is a rail kit I've been looking for, for a while now. So I just wanted to share it.
