    • RE: 请问coolpi 4b 电源输入功率多大合适,有电流保护吗?

      @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。

    • Introduction to COOL PI CM5 interface

      Top-level interface

      1.png

      • The 2X20 pin interface is compatible with CP4 and integrates multiple UART, I2C, SPI, CAN and other functions.

      • Three function keys are PWR, RST and LOADER.

      • 2X2 PIN POE connector,such as CP4.

      • 30pin fpc vertical connector can directly drive standard 30PIN EDP interface LCD. Resolution up to 3840 * 2160

      • The MICRO HDMI-RX interface can support up to 4KP60 video signal input.

      • TF card with self-locking.

      • Two native USB3.0 interfaces, one of which supports OTG function.

      • Two Gigabit Ethernet interfaces, one of which supports POE function.

      • Two HDMI2.1 interfaces with a maximum resolution of 8K.

      • Stereo headphone stand with MIC input function.

      • Two native USB2.0 interfaces.

      • One TYPEC power supply interface, consistent with CP4.

      • The external power interface of 2PIN can support DC power input.

      • 1 standard PCIE 4X connector, currently only supports PCIE3.0 2X/1X mode.

      • SSD interface, only PCIE-M2-2242 size hard disk is supported.

      • Standard 7PIN SATA3.0 interface, 4PIN power interface.

      • M.2 WIFI module interface, supporting multiple general WIFI modules.

      • Dual MIPI LCD interfaces support simultaneous output of two MIPI interface LCDs. The resolution of a single LCD is up to 1920 * 1200. It supports the MIPI DSC function.

      • Four independent MIPI camera interfaces support four camera inputs at the same time. It can be configured as 2X4LINE or 4X2LINE mode.

      Bot-level interface

      The use of cloud storage images requires updating uboot to the latest version. Currently, RK3588/3588S uses a unified image, and machine models are distinguished in uboot. As for the partitions of the image, they are boot and rootfs. Boot stores kernel related files.
      As shown in the following figure:
