Sovol KlipperScreen (Makerbase MKS KLIPAD50)

These pages refer to the RK3328 MKS-Klipad50 board, sold by Sovol as “KlipperScreen” for the SV06/SV06+/SV07/SV07+ printer range.\

The “ACE” product line (e.g. SV06-ACE) uses a different, RK3308 based board. Those are NOT covered by this guide (and as I don’t own such a board, so I can’t tell much about it).
