The 9Tripod X3568 v4 is an RK3568-based SBC, just like the RK3568-EVB.
It always uses soldered connections between the X3568CV2/X3568CV3/X3568CV4 core board
and the X3568bv4 I/O board.

The differences between the core boards
- PCB size, layout
- CPU (RKK3568B2/RK3568J)
- Memory type (DDR4/LPDDR4/LPDDR4X) and size
- eMMC size
- DSI/EDP resistor values
Although the components vary, they maintain full compatibility.

The X3568 board has multiple hardware revisions, and we currently support v4 (I/O board).
