However, like any sophisticated piece of hardware, its performance heavily depends on the firmware running on its mainboard. Finding the correct Two Trees Sapphire Pro firmware link can be frustrating due to outdated forums, broken Google Drive links, and confusion between different motherboard versions (MKS Robin Nano V1.2, V1.3, V2.0, etc.).
