I'm reading the eoma spec at elinux and there is limited information regarding the power requirements. It states "a maximum of 3.5 watts should be respected" and "Type II Cards should not exceed an average of 3.5 watts power consumption" and "must adjust accordingly and stick within the 4 watt heat dissipation budget".

Is there a minimum requirement for supply current that must be available to the cpu card from a housing/device/socket for compatibility with multiple cpu cards (3.5 or 4 watts)?

What is the A20 cpu card power consumption (average/peak)?
