It arrives with an on-board Intel Core i7-8665U processor running at 1.9 GHz base frequency and a maximum turbo of 4.80 GHz. The board integrates discrete AMD Radeon graphics for visual output.

It reuses the laptop's current memory, storage, battery and display cables. Swapping the board restores full platform function without requiring a new enclosure or peripherals.
