    • RE: cool pi 4b 3D 打印外壳 base

      Why not use all the cases for raspberry pi 4 out there with a little modification for the minidp port? That's what I did and it is much better quality than 3D printing this one. Isn't that one of the points of making the Cool Pi 4B in the form of Raspberry Pi 4 is to use as much Raspberry Pi 4 assesscories as possible? But OK. Question for Cool Pi: What's the point of the miniDp port? Why not make 2 micro-hdmi ports like Raspberry Pi 4?

      Does this version have Vulkan support? I tried to run a program with Vulkan and it doesn't work.

      Hello! Thank you for working hard during your Chinese New Year! I don't want to bug you on your break, but when you get a chance can you enable bluethooth on Android? I really need bluetooth for my project. Thanks!

    • RE: 如果制作的启动盘无法加载

      Thanks for the effort but we can't read Chinese. Does Cool Pi 4B only target Chinese users? If so, that's a pity because Cool Pi 4B is a very nice board.

      @george OK. Updating loader file works. But no wifi and bluetooth in this build?

    • RE: Android on Cool Pi 4B

      @大法师 Thank you, but please provide onedrive link or some other link because I can't download from baidu. Does this version also support bluetooth? In addition, does this version enable the use of the top USB3.0 port? The old version makes the the top USB3.0 port unsuable.
      Thank you!

    • RE: microSD Card Performance on the CoolPi 4B

      @Bret Thanks! I see you have different sizes. Does size effect read/write speed? Would it be better or more accurate to test with all same size?

    • RE: Can the Raspberry Display using MIPI DSI work with COOL PI?

      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.

    • RE: Would Cool Pi provide Batocera, Retropie, Lakka, Recalbox devs cool pi 4B boards for support?

      @大法师 But it will be faster and better if you get Cool Pi 4B boards to those devs. They are willing to provide support but they need the boards. Look at orange pi, they seem to be moving at lightning speed in terms of 3rd party software support. We love the Cool Pi 4B form factor because it is 99.9% same as Raspberry Pi 4. Your sales will go through the roof if you distribute these boards to 3rd party devs in the retrogaming scene. Retrogamers love your Cool Pi 4 but they are afraid of lack of support.
