Power & Source of Big Ideas

SATA HAT using Marvell 88SE9215 Chipset. In datasheet is info about power consumption up to 1W... But SATA HAT (without drives) consume much more. I think - something is wrong in HAT design... :cry: I need to add small fan too :cry: Is here some way, how to drive this fan speed to make them: * less ...
Because 4GB variant doesn't cost $50. M4V2 cost $70, but M4 4GB was for $75.
I had same problem - no HDMI output, only solid red & twice flashing green LED.
Lot of of iso files - still same. Then I changed power supply - from modern 20W power supply with fast charge support to old 5V@2A charger and voila! Its works!

Maybe can help for someone ;)
