Subject: | Re: [Paparazzi-devel] Powering the servos for Yapa and doubt about the airframe file |
Date: | Wed, 21 Mar 2012 22:23:15 +0100 |
Hello,I have a couple of questions:1) I know that for Yapa2, I can write the airframe configuration file with either twog or tiny as board. Is there any difference between writing any of them?2) I want to power externally the servos. I know that it is possible but I don't find a clear procedure. Given my little experience with batteries and the fact that I already burned a Yapa, I would like to clearly know which procedure to follow. Any 5V battery would be fine? Where should I connect it? I don't want to brigde the Yapa for this since I have read is not too recommendable. I use Futaba S3305. Details of these servos can be found below. Futaba also states: "Per Futaba this servo is approved for use with NiCd batteries ONLY! This servo can produce high-current draw from your batteries. If using NiMH or LiPo batteries, make sure they are capable of delivering sufficient amps."
