Schematic PDF for Creality mainboard version 4.2.7, with a date code of 28-5-22 in the name. Creality 4.2.x boards drive many of the brand's 3D printers, and this drawing helps trace stepper driver wiring, heater MOSFET outputs, thermistor inputs and the power supply section. It opens in any PDF reader and is handy for checking connector pinouts or a failed hotbed circuit. Confirm the version printed on your board, because 4.2.2 and 4.2.7 differ mainly in their stepper drivers.
