EQ5 and 6 mounts require a minimum 4 V to make it work not the other way around.
I would check the specs properly on the EQ8 if it is 3.3V then many people have it connected wrong. It may work OK for a period of time but may fail very early voiding any warranty.
3.3V is also a high speed logic level so running at 5V will limit the speed of communications as well.

The schematic for the hand controller that appears in the EQ8 users manual shows both the TX and Rx lines as 3.3V so I assume that distinguishes it from the EQ5 and 6. I read somewhere that the interface is 5 volt-tolerant but is designed for 3.3.
