RE: 买的lcd屏幕 hdmi的在orangepi里有显示。但是在你们这个板子上黑屏posted in Ubuntu
@tscmga 在你自己做的这个板子上面把HPD信号的驱动能力增强试试。极限情况下可以直接接5V.
下面这款我们有测试过:

@tscmga 这种非标设备暂时没有很好的办法兼容,会导致故此失比,我们之前有测试一款7寸的HDMI+USB触摸的是可以正常使用的,晚一点发链接给你。

RE: 请问coolpi 4b 电源输入功率多大合适,有电流保护吗?posted in Peripheral
@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。

@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.
