RE: CoolPI 4B-PRO Product Introductionposted in News
@Mz3D-0 This product is currently not in mass production, and a separate prototype can be provided. Alternatively, it is recommended to pay attention to the CM5 machine, which offers two types of products: EVB and NOTEBOOK.

RE: CoolPi 4B硬件扩展一：40PIN接口介绍posted in Hardware
@AugustRobot_Zou 按照5V 3A的标准来配置。一般散热按照12W评估。正常工作也就5W左右。

RE: RK3588 coolpi 4b找不到测试8k解码的方法posted in Pi 4B
@test 3588 8K视频解码是有部分限制，目前ubuntu22.04使用GST可以比较流畅播放。其它系统版本暂时不行。这里不是解码的问题，是显示的数据格式转换问题。如果开发8K视频类应用建议直接使用ubuntu22.04或者android。

RE: android 12系统怎么加入特殊分辨率？posted in Pi 4B
@yushaotai 还有就是EDIE读取回来的时序，要和实际写到代码里边的数组一致，否则也不能正常显示的，你需要什么分辨率？

RE: CoolPi 4B硬件扩展四：GPIOposted in Hardware
@zensation
If you need to use PWM function, it is recommended to use PIN12 (PWM3-M3). This port defaults to the pull-up port, and you can increase the resistance to ground by 2K. The default level can be reduced to below 0.6V. If you need GPIO function, except for PIN3 PIN5 PIN32 PIN40 PIN8 PIN10, all other IOs can use pull-down resistors to change the default level.
