"OK thanks Dean!

the APM2.5 has a very odd power system. there are to date 20,134 different ways to run power to it. LOL"

"hey dean... the package looks like its UAVPWR (not UAVPWR2) i think im looking at what you made before LOL

thanks for the advice on the LC filtering. Does the APM2.5 have an lc filter and LDO when i apply 5V into one of the APM's input pins or when…"

"hi dean... that sounds great.

I just realized that my LC filter wont handle the load of servos (1A max). Can you advise me on what kind of filter i can build that can handle the load... or do i even need one since you are building one into the new…"

"thanks dean! im gonna look this over. looks like were not using the 2 output idea then, right? i wish i had one idea of what your design means... electronics theory mostly eludes me.
is it ok if i share your design  on other forums ( crediting you…"

"hi dean....

just found this... based on a LTC 4416.

not sure if this helps.

"the 4412s do look better.. way easier to solder to i suspect. Ill order them up and send them to you if you want. theyre only $2 direct form linear."

"yes the guy who made the post showed them switching over with no reboots. I am thinking now that the SBECs I have will output 6.4V or so and even a 700mv drop would still be to high for my APM 2.5.

Thats why I was interested in the 4415... only…"

"OK Dean thanks for the insights.
I have 2 of the 4415's coming... would it be worthwhile to send them to you for testing? I dont know if Im wrong but I thought the max V of the 4415 was OK for my application ( a tricopter with 1 tail servo and a…"

"hi dean....

I was planning to use the 4415. I can send you what i made.... its likely no good. can I PM you a copy?

Hey if you can design a simple board Id gladly paypal you something for your time... and thank you very much for the offer, thats…"

"thanks dean! I looked at it but it seems its for the other model of chip. Im not sure I have the expertise to make this work... I made a pcb with dip trace but I dont know how to export it as a pdf for people to look at.

Im trying to run both the +…"

"Hi everyone...

On page 2 of this thread Dean Franks posted a schematic or PCB layout but the link is dead....


does anyone have a copy of this file?

Im trying to make the LTC 4415 work with 2 turnigy lownoise 3A SBECs.

thanks
