which variety of the CM4 Module #6

Just wondering... which variety of the CM4 Module (with EMMc memory, with MictoSD card, with or without WiFi, with 2,4,8 GB RSM is presumably the best bet? Thanks!

Hello Careyer, EMMc is mandatory, ochin board doesn't have the sdcard header. The reasons why are: save space for other connectors (i wanted to keep the same size of the cm4), emmc is much faster and durable, the interface is used for emmc OR sdcard (cm4 with EMMc doesn't work with sdcard). If you want to use OpenHD 16GB are enought (maybe 8GB but not sure). I'm also developing a sw, totally different in goal and type from OpenHD and it may need more space, i'll tell you more very soon. About the RAM, OpenHD guys say that 1GB is enought, with other sw you may need more, depends on what you want to do, for example for computer vision, machine learning etc, more is better. In my opinion 16GB EMMc 2GB RAM is a good option, but if you want to develop sw you better go to 32GB.

Thank you! Shall i take a variety with WIFI+BT or without? I mean ... will it interfere when using external Wifi adapters?
