Optimal external power source

power

#1

Hi,

We have the 2.7 version and we are trying to plug an external power supply. We’ve been reading in the forum and we think that we need 12v but our problem is about the current. What is the optimal current?. Thank you.

Hi Jose:

You need enough current so that the board boots without a drop in voltage. I don’t know exactly what that would take, but I would get at least a 2A or 3A power supply. Note that this is enough to spin the propellers in air, but is not enough to drive the motors in water.
