Notice:
When the SKR motherboard is electricity , the red light D2 in the lower right corner will light up, indicating that the power supply is normal. The middle of the Board DC SEL is the power selection end
1, when using USB to power the motherboard, short circuit cap should be used to connect +5V and USB Pins
2, when using 12v-24v power supply, short circuit cap shall be used to connect +5V and INT pins

Attention: Can be connected [12v-24v power], [USB] at the same time , the printing process must be connected with a short circuit cap +5V And INT
3,The Board 5V SEL must be connected to INT and +5V two pins before it going to print 4,It must be connected with an external hot bed MOS Extension Module if you need to use with Heatbed, it is very significant that Motherboard can not connect with heat bed directly.

How to use
The SKR motherboard connects with the computer via the [USB] interface. After the driver is installed, the motherboard can be inserted into the computer to recognize the port for data transmission. Without the driver installed, it is easy for the computer to not recognize the USB port

1,The driver can be obtained from our open-source website: https://github.com/bigtreetech, named by “mapleDrv” file
2. After installing the driver, connect the computer and SKR motherboard with USB cable
