ClusterBoard questions (eMMC, consoles, etc.)

[arrigo]

I've been looking at the Wiki and through the threads here and have a couple of questions on the ClusterBoard I have just received:

1) the eMMC slot maps to the SOPINE module in slot 0, correct? The other slots cannot be connected to the eMMC?

2) where does one connect the serial console for the SOPINE modules? I bought the serial console "PINE64 USB SERIAL CONSOLE/PROGRAMMER" but where should I connect it to access the consoles of the SOPINEs?

3) reading the threads it seems that heat is an issue: I bought my three SOPINE modules without heatsinks - is the ROCK64 / PINE A64 / PINE H64 Heatsink OK for the SOPINE?

4) are there pins on the ClusterBoard where one can connect fans (see 3 above)? Should they be powered independently or is there somewhere to pick up a 5V supply off the main PSU?

I plan to run my ClusterBoard as the "CPU cluster" off a Rock64Pro NAS providing disk space so thermal issues are important for me.

Thanks,

Arrigo
