Creality 4.2.2 mainboard schematic in PDF format, carrying a 28-5-22 date in the name. The 4.2.2 board is common in Creality printers, and the diagram shows how the stepper drivers, heater outputs, endstop and thermistor inputs and voltage regulators are wired. Repairers use it to find a blown MOSFET, a dead regulator or a miswired connector. Check the silkscreen version against 4.2.2 before relying on it, since the related 4.2.7 board uses different driver chips.
