Matek 405 build advice

mateksys-f405-std
(Rusty Marmot) #1

I managed to get a standard Matek 405 FC pretty cheap so thought I would build a small quad with some bits I have leftover from crashed quads. I’m going to use a Matek PDB XT60 that has a BEC 12v and 5v.

The FC loaded firmware 3.7.0 without a hitch so I would like to add a current and voltage sensor to the setup.
Q1/ Suggestions for which sensor to use and
Q2/ How to wire and set up.
Q3/ I could work it out by trial and error but does any know in advance which signal pad number matches which motor number.

Theres lots of info in the docs:http://ardupilot.org/copter/index.html

See here for a few power module options:

http://ardupilot.org/copter/docs/common-powermodule-landingpage.html

How much current do you expect to draw? if its is <60A continuous, <90A burst, you can use the classic 3DR design power module: http://ardupilot.org/copter/docs/common-3dr-power-module.html
They are available pretty much anywhere and a pretty cheap. Search for “3DR power module”

If you expect to draw more than that, then I recommend a Mauch Power module:http://www.craftandtheoryllc.com/product-category/mauch-hall-sensor/

See the above links for wiring.

Here is a link that describes configuration through mission planner:

Thanks for that. I really appreciate the input. Do you know how to wire up one of these power sensor modules to a Matek 405 Flight Controller ?
