Supported Motherboards %26 Wiring Guide - thisiskeithb/PrusaAIO GitHub Wiki
Note
To simplify wiring, I recommend picking up an SKR Extension Cable Kit which converts Prusa's wiring to JST connectors (not needed for BTT002).
Important
Prusa MK2.5S users must swap to 12V hotend cooling fan (4010) since the stock fan is 5V. Stock parts cooling fan (5015) is 12V, so that should work without an issue.
