@night 机器TYPEC前端电源芯片耐压可以达到28V，极限可以到34V，所以你的适配器规格没有任何问题。
开发板的电源部分一直是我们设计最优先考虑的方向，所以前端第一级电源花了很多功夫，考虑到用户各种各样适配器的规格，最终选择目前国内少数几家真正能做车规级别电源方案的厂家。尽量保证前端电源稳定可靠。

If you need to boot armbian normally, you need to update the loader file to version 0104.

Follow the steps below to update the loader:

• Download the latest loader file One Drive
  ![5594e1d4-3a7b-46fc-a7b5-2a9fe418dfc0-image.png]
  

• Short the 2 pins shown by the arrow.
  

• The USB interface and computer connection.
  

• Plug in the power supply and open the upgrade software. The machine enters the maskrom upgrade mode.
  

• choose to write by address
  

• Click Execute to complete the loader update.
  

• If the computer prompts that the USB driver cannot be found, please download and install the driver software first.One Drive
  

1.Introduction

Cool Pi has a modern and powerful hexa-core ARM based processor, RK3588S inside, it offers significantly improved performance versus other popular SBC boards. All models are equipped with LPDDR4X RAM and optional high performance eMMC modules, boost all applications.

2.Machine size

The size is only 56mm × 85mm.

COOLPI-V11-20220911.dxf

3.Performance

4-core A76+4-core A55 gold combination, giving consideration to high performance and low power consumption.

CPU

测试方法：

sudo apt install sysbench

RK3588S单核心每秒事件数2598，8核每秒事件数13846；同步对比 i7-7700 ，单核每秒事件数1438，8核每秒事件数8469。可见ARM在CPU方面并不比X86弱。

GPU

测试方法：

sudo apt-get install glmark2* -y

X11 gl

X11 gles 3.1

WAYLAND gl

WAYLAND gles 3.1

@zensation The radiator can be matched with raspberry pi. A separate fan is OK. Normally, it is not necessary to add aluminum alloy fins on the CPU.

内核已经更新，同步develop代码到最新，编译替换内核，KO文件解压到/lib/modules目录，重启机器会看到两个WIFI节点。

使用其中一个连接外网

另外一个可以作为热点

The latest ubuntu22.04 firmware（20230303-ubuntu-22.04-preinstall-desktop-arm64） integrates ffmpeg and gstreamer video frames, and can call the hardware codec module of Rockchip, which can greatly improve the video codec performance of the device and reduce the CPU load.

• With kmssink, the CPU utilization of 4K video playback is reduced to about 10%.The disadvantage is that it occupies one layer.

• The following command can obtain layer information.

   sudo cat /sys/kernel/debug/dri/0/state | grep "plane"

• Use the following command to play the video and replace xxx.mp4 with the actual path. 88 represents the layer, kmssink only supports the display of Esmart layer.

   gst-play-1.0  xxx.mp4 --videosink='kmssink plane-id=88'

• You can also use other plug-ins, such as xvimagesink glimagesink waylandsink, etc.

CoolPi的MINI-DP接口只能支持标准的DP协议，分辨率可以达到4KP60，不能支持INTEL DP++协议，所以市面上普通的minidp转HDMI线材大部分是不能使用的。DP转HDMI线材需要使用主动式的线材。下图是几个验证过的线材的链接地址：

@xingzhan2012 声卡选到耳机输出

@allen 看看内核部分是否确认一些配置。自己加上更新一下。

@xingzhan2012 四月初各个店铺上架。

@lej40 said in Type c power port:

Is the the type-c PD port also a USB-c data port

Sorry,This port is used for power supply and has no data connection.

@tonyone0902 如下图所示，板子的BOTTOM面有测试点，可以焊接外部电源。

机器本身不具备电量侦测功能，可以外加库仑计通过I2C接口。

@tonyone0902 最低输入电压5V，所以并联是不行的，串联12V从TYPEC输入没有问题。

• Product image
  
  

• All interface functions have been debugged and are currently undergoing performance optimization.

• It is expected to be sold normally in early April.

@test 这是没有正确识别到TF卡的系统分区，TF卡先格式化一次，然后重新制作启动盘。

@xingzhan2012 摄像头的调试周期会比较长，做AI部分对摄像头像素要求不会太高，可以考虑先使用USB接口的摄像头模组。
