      @大法师 建议尽快支持一下树莓派的HQ Camera,传感器型号是IMX477R,现在这款摄像头很火,可以匹配各种不同的镜头。IMX708支持自动对焦,是新出的产品。

      @大法师 The latest ubuntu22.04 image can already support this camera.

      20230210-ubuntu-22.04-preinstalled-desktop-arm64-coolpi.rar

      V4L2-TEST can start the camera by operating the video11 node

      B

      @retroman Because the pi 4b box has no power key location, direct use will cause pwr key is stuck. In addition, the size of the DP output port is larger than Pi 4b, and the size of the metal radiator of PI4b is too far from the DP interface. 3D printing is the only option before the surrounding accessories of the cool pi come out.

      Does Cool Pi 4B support parallel RGB like the Raspberry Pi 4b? I would love to put Cool Pi 4B board in the PiBoy DMG instead of the Raspberry Pi 4B.

      @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.
