Note: The SSD installation instructions can be found here.
The SSD slot on the BrightSign XTx43/XDx33 is an M-keyed M.2 connector compatible with SATA drives. NVME/ACHI drives are not supported.
We recommend 80mm SSD modules for use with these players. There are holes to accommodate standoffs for 42mm and 60mm SSD modules, but you will need to install your own standoff to secure the module to the circuit board.
