Vehicles - MultiRotors / Re: Current sensor for osd

You are welcome.

What the difference between attopilot 45A, 90 A and 180A?

It is the maximum current that can go through the sensor. If you think your motors won't pull more than 30A and you have 4 motors, then just 4*30A = 120A max.
You can add 15% for safety so 120+120*0.15 = 138A. Power boards I linked are 184A and 140A (each output 35A max per motor).

OSD with data from FC gives you more info, like current, voltage, heading, throttle, flight mode, GPS, RSSI etc.. which is nice. On tiny models I just want voltage, so I skip OSD and use RunCam Swift Micro 2 camera which has input for battery 8-36V that does OSD but only overlays voltage info.

Can i use this one?
 http://s.aliexpress.com/yaqUrUra

This says
"Voltage and current measurement configured for 5V ADC"
The ADC on the Revolution is the 3.3V one. So no, you can't. You need voltage divider that scales voltage to 3.3V level.
There are plenty PCB boards that do include votlage dividers that scale voltage to 3.3V level.

For example this one https://www.banggood.com/Matek-FCHUB-6S-Hub-Power-Distribution-Board-5V-10V-BEC-Built-in-184A-Current-Sensor-p-1147591.html
Says ADC 3.3V. All STM32 chips to my knownledge have 3.3V ADC (Analog to digital converter) used to measure voltage.

So don't order the one in your link, 5V feed to ADC would fry your Revo.

These two power distribution boards do have OSD included

Hello.
I'm new in the world of multirotor.
I have make a quad500 with revolution board.
I have a minimosd but when i connect my batterie on it i don't have my batterie level (stay at 0.00V).
So i think i need to use current sensir who is connnect to the revo board.
Librepilot said to use this one https://www.sparkfun.com/products/9028
But it's hard yo find it.
Can i use this one?

I still haven't seen the question answered as to whether the user has installed the LP bootloader using the links already supplied.

What happens when you try this:
- Disconnect board
- Click Rescue button
- Connect board

Please post a picture with your board.

Both wiki pages are ok.

Latest next build can be found here: LibrePilot-16.09+r522-gd9cce5e_i686.exe

what affraids me is that i don't know, when i change firmware inside 'next', what i need to recalibrate, or change settings...

I tried future 16.09  when it was yet 'next' and that was my problem.

But I can give a try if you give me a link for installing next please.

In particular are  the
- https://librepilot.atlassian.net/wiki/spaces/LPDOC/pages/57671696/Linux+-+Building+and+Packaging
and
- https://librepilot.atlassian.net/wiki/spaces/LPDOC/pages/14876735/Windows+Building+and+Packaging
up to date ?

Thank you

what is missing for me is an ASWA function that works.
I don't really want to move to next version because it can be buggy.

Ok, but naming something "release" won't make it less likely to have a bug, it is usually more reliable because people fly it, which you don't want to ? :)
Any software can have bugs and actually it is more often the case for software that is released more frequently (statistics).
Think about like this, "next" contains latest fixes, that are not released yet.

I do fly "next" since OP days on all my builds, never complained, few times I had issue when I got new hardware which was not popular yet, but then it got fixed in 1 day after submitting jira ticket and I didn't even have to wait for any release.

P.S If you need help with compiling just let me know, I am glad to help.
