二、SKR 主板通电
SKR 主板上电之后，左下角的 D4 红灯会亮起，表示供电正常；板子中部的
5V SEL 是电源选择端；
1） 当使用 USB 给主板供电时，需用短路帽连接+5V 和 USB 两脚；
2） 当使用 12V-24V 供电时，需用短路帽连接+5V 和 INT 引脚；
注：可同时接【12V-24V 电源】、【USB】，打印过程必须用短路帽连接+5V
和 INT 两脚。
After the SKR motherboard is powered on, the red light D4 in the
lower left corner will light up, indicating that the power supply is
normal; The middle of the board 5V SEL is the power supply selection
end;
1) when using USB to power the motherboard, short circuit cap
should be used to connect +5V and USB feet;
2) when 12v-24v power supply is used, short circuit cap shall be
used to connect +5V and INT pins;
Note: it can be connected to both [12v-24v power] and [USB] at
the same time. Short circuit cap must be used to connect +5V and INT
in the printing process.
三、SKR 主板与 PC 通信
SKR 主板通过【USB】接口与 PC 通信，需要装驱动才能正常使用。
1. smoothieware-usb-driver-v1.1 驱动安装
驱动可从开源网 http://smoothieware.org/windows-drivers 获取；
2. 安装完驱动，用 USB 线连接 PC 和 SKR 主板
打开电脑“设备管理器”，可查看到“smoothieboard USB Serial”异步通信
口所属的 COM 号。
SKR motherboard through the [USB] interface and PC communication, need to
install the driver to use normally.
1. Smoothieware-usb-driver-v1.1 driver installation
Drivers are available from the open source web at
http://smoothieware.org/windows-drivers
2. After installing the driver, connect the PC and SKR motherboard with a USB
cable.
Open the computer "device manager", and you can see the COM number of
"smoothieboard USB Serial" asynchronous communication port.

五、SKR 主板固件说明
出厂的主板里会装有测试使用的固件（I3 机型），可以直接使用，也可根据己
需自行更改。
1. SKR 主板固件获取方式
问客服或者技术人员获取；
登录开原网址进行下载：https://github.com/Smoothieware/Smoothieware
2. SKR 主板固件更新方法
1） 在下载好的固件包中选择适合自己机型的文件拷贝到SD 卡根目录，包括：
①固件 firmware.bin（根据自己机型进行选择）
②配置文件 config.txt（可根据自己需求自行更改配置）配置文件中的详
细功能选项可参考开原网址：http://smoothieware.org/configuration-options
注：不可更改文件名，firmware.bin 必须为小写！
2） 将 SD 卡插入主板 SD 卡槽中，重新上电或者按一下复位键，等约 10S 之
后即可更新完成；
Our motherboard will be equipped with firmware (I3 model) for testing, which can be used
directly or can be changed according to your own needs
1.The SKR motherboard firmware access method：
Log on to the open source site to download：
https://github.com/Smoothieware/Smoothieware
深圳市必趣科技有限公司
BIG TREE TECH
2.2. Firmware update method of SKR motherboard
1) select the file suitable for your model from the downloaded firmware package and copy it to
the SD root directory, including:
(1) firmware. bin (all that can be decided based on your own machine)
(2)Configuration file config.txt (you can change the configuration according to your own needs)
The details of the configuration file can be referenced in the open source web address:
http://smoothieware.org/configuration-options
Note: file names cannot be changed, firmware. bin must be lowercase!
We do not recommend using the tmc2130 spi on this board. If you really need to use spi on this
board, you need to change the firmware by yourself, and we do not have relevant firmware to
provide. In order to make it more comfortable for you to use, please directly use the STP/DIR
mode of tmc2130

六、注意事项：
1.
主板 5V SEL 必须连接INT 和+5V 两个引脚，方可进行
打印（即必须有 12V-24V 电源给主板供电才能进行打印）；
2.
主板所接热床功率必须小于等于 110W（即热床电阻值
大于 1.3Ω），要是用大功率热床时，必须外接热床功率扩
展板；
3.
SD 卡中的固件文件名字不可更改（包括大小写）；
4.
接线过程和插驱动过程必须是在断电前提下进行，在检
查线路正确连接及驱动正确插入后方可上电，防止接错线导
致主板和驱动被烧毁，造成不必要的损失；
5.
若要更换配置文件，请将出厂的配置文件备份，以记录
各
部分芯片引脚标号，然后对新的配置文件进行更改！
Attention:
1. 5V SEL of the motherboard must connect INT and +5V
pins before printing (that is, 12v-24v power supply must
be provided to the motherboard before printing);
2. Hot bed board receive power must be less than or
equal to 110 w (that is, the hot bed resistance is
greater than 1.3 Ω), if with high power hot bed, have
to external thermal power expanded bed plate;
3. The wiring process and plug-in driving process must
be carried out under the premise of power failure. The
power can be turned on after checking the correct
深圳市必趣科技有限公司
BIG TREE TECH
connection of the line and the correct insertion of the
drive, so as to prevent the wrong connection of the line
from burning the motherboard and drive and causing
unnecessary losses;
4.If you want to change the configuration file, backup
the factory configuration file to record the pin number
of each part of the chip, and then make changes to the
new configuration file.
