The board can only be powered by V_IN - in my case,
like you I chose to connect the battery directly to this pin to run the two
board regulators - 3.3v & 5v.
The V_BATT pin is solely to register the battery in
the GCS. I solder bridged Jumper 2 to register the battery voltage from the
V_IN pin.
Others are not closing this jumper and registering
the battery voltage connected to the V_BATT pin and powering the board via the
ESC on the V_IN pin.- not applicable in your case I would have thought
using i2c.
And I would certainly not use the board's 5v power
rail to drive servos or anything else, only to send the
signal.

Hi,
Thanks for the doing the diagram. I received my Lisa/M yesterday and had it
up and running within an hour thanks largely to this.
One comment on the power supply: with the board in its default state (no
jumpers bridged) I needed to apply power to V_IN (I chose to use 11.1V for
testing). Using V_BATT as indicated in your diagram would not power the board
which puzzled me at first, but then I didn't have the ESC and servos in place as
I am using I2C and no servos.

@ Eduardo It seams that 11.1V (or what ever) is
to high to use it directly. I think I'll take the 5V/2A BEC from my ESC
to V_IN and connect the battery to V_BATT like you. (I think you've mixed
up the vin and v_batt in your text)
@ Stephen As far as I see -
you've connected the 11.1V to V_IN. What did you do with the
Jumper?
I've studied seen the Jumper part before but there is a thing
that I don't understand: From the Wiki: "In our case the ESC will
supply both the servos and the board with power from the main battery. This
is the default setup of Lisa/M, so there is no need to solder anything on the
board. "
My LisaM has no Jumper soldered yet. So it's "default". This
means now I can power the board by connecting BEC (SERVO1 SV/GND)? and the
Battery to V_BATT.
So what happens when I solder JP1? I think this
will connect the V_IN to SERVO1_SV to use the BEC power to power the
board.
---> Main question ;-) : So: All Jumper not bridged
-->Battery to I2C1 V_BATT and BEC 5V to V_IN or to SERVO1_SV?
I
hope my suggestions aren't too confusing ;-)

Bruzzlee, the correct way to powert lisa/m is the i2c1 as you
say. The vin in used to monitor the battery voltage. In my setupi i
use 7v to power the lisa/m because the onboard regulator work very HOT
with 12v. So i connect the vin directo to battery and a 7v to v_batt
pin.

[Paparazzi-devel] Lisa M wiring layout
Thanks for the
answers.
@ Eduardo Of course I will share my tests to the
community
@ Eric Is the Lisa M usually been powered by the I2C1
CAN plug with 11.1V? Because this looks strange to
me...

Bruzzlee, i am using lisa/m too. Please, report your
tests to the group.
I have strange behavior with my
copter. Some of this caused by vibration and other that i not know
the cause.
