The Four In One ESC for Pixhawk from Hobby wing & Favourite

Published by editor on February 22nd, 2017 - in Uncategorized

Like to perches Quattro ESC visit
The Four In One ESC is a great option for Quadcopters, it has several advantages over individual ESCs.
• Four in One “Quattro” ESCs are available in 20 and 25 amp 2 to 4 cell versions and a 30 amp 2
to 6 cell version.
• The 4 in 1 ESC centralizes all your power wiring and eliminates the need for a power distribution
board or block.
• The thick aluminum plate on the front of the ESC serves as a heat sink which is more than adequate
for normal use.

• The design eliminates DC power wiring to individual ESCs reducing DC magnetic field and
interference to magnetometer.
• The ESC comes with a good length of quality high flex motor wire which terminates in standard bullet
• For use in a quad copter with a controller which has a built in magnetometer the ESC should be
mounted aluminum plate side up..
• The Four in one ESC is great for building new quadcopters or for retrofitting to old ones and it is easy
to install.
• Using the available ESC “Throttle Signal Hub” Below all 4 internal ESCs can be programmed
and calibrated at one time.
• On the site I link you to above, the “Hub” comes with the more expensive version of the 20 and 25
amp ESCs. (Get The “Hub”).
• I also (VERY) highly recommend the Hobbywing ESC programmer on the right below for much
easier programming.

Calibration and Programming Below is for 20 and 25 AMP ESCs, 30 Amp
For a PX4 or Pixhawk the receiver needs to be set to standard (not PPM-Sum) mode.
(Optional!) Four In One ESC Calibration using all at a time “Hub”

• Optional! Calibrate all four ESCs at once using the “hub” and your RC transmitter and receiver.
• Later it is necessary to calibrate the ESC while connected to the APM or Pixhawk, so this step
probably has no benefit.
• At this time for an APM, PX4 or Pixhawk I recommend you skip this procedure and go to
“Programming” the ESC below.
• If you are going to perform this calibration the receiver will need to be temporarily set to standard
(not PPM-Sum) mode.
• The ESC should be installed in your copter and connected to the motors but with props off, motor
direction does not matter now.
• Solder the ESC’s main power and ground wires to your battery power input connector (Do not
connect the battery at this time).
• Connect all 4 ESC signal cables to the “Hub” block in any order but be sure black wires are the – and
white are on the S side.
• Connect the “Hubs” 3 wire cable to your RC receivers throttle channel ensuring signal and ground
are on correct sides.
• Turn on your RC Transmitter and put the throttle stick all the way up to full throttle.
• Connect the battery to the main power connector, (This is the step to return to for a repeat
attempt on any failure below).
• You should hear 3 short beeps followed within 6 seconds by another two beeps (If not disconnect the
battery and try again).
• If above is OK move the throttle all the way down: Two more beeps within 3 seconds indicates
calibration is done.
• If it did not produce the final two beeps when the throttle was lowered, repeat the procedure from
the beginning.
• Once it has produced the final 2 beeps move the throttle up just a bit to see if all 4 motors start at the
same time.
• If the motors start at significantly different times, repeat the procedure, otherwise calibration is
• When you are satisfied with the calibration disconnect the main battery and turn off your RC
Connect the Four In One ESC to the Quadcopter
• Mount the ESC with 2 strips of Velcro tape in your quadcopter with the Aluminum plate on top.
• Note in the image below left the 4 in 1 ESC is tucked between the two upper frame plates on my FLIP
Sport quadcopter.
• Connect the Motor leads to the four motors based on convenient wire connection (we will remap
them as needed).

• Write down the motor (M1, M2, M3, M4) connected to each ESC signal (S1 – Red, S2 – Orange, S3 –
White, S4 – Brown).
• Plug S1, S2, S3 and S4 ESC leads into the APM, PX4 or Pixhawks M1, M2 , M3 and M4 outputs
according to the data above.
• Make sure the ESC control signal wires are on the correct edge of your autopilots servo buss, APM
and Pixhawk are opposite.
• If you are not using the ESC’s BEC to power the Autopilot Servo Bus, disconnect the red power
BEC wire from the ESC.
• The ESC’s BEC power lead is the center (red) wire of the S3 BEC Signal cable between black – ground
and white – signal.
• If you need to disconnect BEC power remove the pin from the connector and tape it so you can
reconnect it for programming.
• For the PX4 you normally use it’s built in power supply and for the Pixhawk you normally use it’s
supplied power module.
• However, both of these also permit isolating the servo bus power to allow separate power to be
provided for external servos.
• If you are going to use additional external servos you should isolate the bus and leave the ESC’s BEC
red power wire connected.
• If you are using an APM without an additional power supply, leave the red power wire from the ESC’s
BEC connected.
Configure the Autopilot with the ESC
• Connect the APM, PX4 or Pixhawk Autopilot to Mission Planner with the USB cable.
• Also ensure there are no propellers installed and connect the flight battery.
• Place the copter on a table in front of you with the rear of the copter nearest you.
• In Mission Planner, select the Terminal Mode tab and select test mode then select Test, Motors.
• The motors should each rotate in a clockwise sequence beginning with the right motor furthest from
• Based on APM notation right front is motor 1 and rotates first then motor 4 then motor 2 then motor
3 as in image above right.
• If the motor order is not correct move the ESC’s signal cables on the autopilot servo bus until motor
order is correct.
• It is important that each of the motors has a similar performance when it is powered up.
• You must ensure that the direction each motor turns is correct as indicated in the above right image.
• If a motor is not turning in the correct direction simply exchange any 2 motor / ESC wire connections
for that motor.

• At this point you can also recalibrate the ESC through the APM and Mission Planner if you feel you
need to do so.
• Disconnect the Battery from the copter and the USB cable from the AutoPilot.

The AS5048 is a magnetic Hall sensor system manufactured in a CMOS process. A lateral Hall sensor array is used to measure
the magnetic field components perpendicular to the surface of the chip. The AS5048 is uses self-calibration methods to
eliminate signal offset and sensitivity drifts.
The integrated Hall sensors are placed around the center of the device and deliver a voltage representation of the magnetic flux
Through Sigma-Delta Analog-to-Digital Converter (ADC) and Digital Signal-Processing (DSP) algorithms, the AS5048 provides
accurate high-resolution absolute angular position information. This is accomplished by a Coordinate Rotation Digital Computer
(CORDIC) calculates the angle and the magnitude of the Hall array signals.
The DSP is also used to provide digital information at the outputs that indicate movements of the magnet towards or away from
the device’s surface, in the z-axis.
A small diametrically magnetized (two-pole) standard magnet provides the angular position information. Depending on the
system requirements different magnet diameters are possible. Additional flexibility is given by the wide range of the magnetic
input range. The AS5048 can be combined with NeFeB, SmCo and alternative magnet materials e.g. hard ferrites. The AS5048
provides a 14-bit binary code representing the angular position of the magnet. The type of output is pre-programmed as SPI
version A or I2C version B. Simultaneously a PWM output signal is available in 12 bit format.
A simple programming of the zero position is possible over the interface. No additional programmer is needed. The AS5048
uses one time programmable (OTP) fuses for permanent programming of the user settings. The verification is possible over a
simple digital readout of the OTP content.
The 16 bit SPI Interface enables read / write access to the register blocks and is compatible to a standard micro controller
interface. The SPI is active as soon as CSn is pulled low. The AS5048A then reads the digital value on the MOSI(master out
slave in) input with every falling edge of CLK and writes on its MISO (master in slave out) output with the rising edge. After 16
clock cycles CSn has to be set back to a high status in order to reset some parts of the interface core.

DIY Rasberry PI HD FPV & wifi telemetry Pix hawk

Published by editor on June 3rd, 2015 - in Uncategorized


My DIY HD FPV project just doing some testing now using wifi

what trying to accomplish stream real time HD video from a small drone, as well as connect to GCS on the same wifi network. I attempted this last year gave up on the Raspberry PI move to a much faster board, after the release of PI 2 I decided to try one more time;  for an fordable price and lots of man hours in work ;).

Parts used: 

1. raspberry PI 2

1. pi camera

1. camera mount or

1. project box

1. wifi adapter

1. 4 gb SD card

1. double sided Velcro tape

1. USB to RC BEC adapter/iphone charger

1. copter Pixhawk ESC MOTORS from

suggest smaller Wifi adapter you must supply 5V 2A to the adapter. both adapters have the same chip set but smaller one works better.

wifi install

camera install

Set up Raspberry PI to connect to Pix Hawk, do not auto start services from /etc/init.d/ skip that part .

there are some more cavorts to this seal to comport communication need to be set up .

prepare com port of Pix Hawk:

sudo apt-get update 
sudo apt-get upgrade

sudo apt-get install python-dev

sudo usermod -a -G tty pi
sudo usermod -a -G dialout pi

sleep infinity >/dev/ttyAMA0 &

sudo apt-get install ser2net

sudo nano /etc/ser2net.conf

add to the bottom of file so you can connect to Pixhawk/APM over wifi on TCP port 2000

2000:raw:600:/dev/ttyAMA0:57600 8DATABITS NONE 1STOPBIT banner

sudo /etc/init.d/ser2net restart

sudo apt-get install apache2 -y

Check to see if the camera is working ” you can add video embedded code to html page here can be viewed here ” http://PI.IP.ADDRESS.

raspistill -v  Test the camera is up and running all streaming apps are installed, using raspistill module and VLC to display video on port 8554. Also 8081 8080 should work, recording can be done from the client end VLC. Http server is also running on PI you can access video there if IP changes edit ip on page.

Run Video command: (disable motion from starting at boot id you ar not using this module for FPV)

sudo apt-get install vlc

sudo apt-get install motion

sudo apt-get install libv4l-0

sudo apt-get install uvccapture

dmesg | tail, you should see you camera attached in the output message, if it is connected to your HW

edit /etc/default/motion and set “start_motion_daemon” to no( you do not want to auto start )

edit /etc/motion/motion.conf edit the settings

set “daemon off”

Start video stream run the following commands: choose with script works for you run it at start up.

raspivid -o – -t 0 -n -w 720 -h 480 -fps 25 | cvlc -vvv stream:///dev/stdin –sout ‘#rtp{sdp=rtsp://:8554/}’ :demux=h264

This command to a script by using the following

sudo nano sudo nano

sudo chmod +x

start the stream automatically:

If you want to start the stream automatically you have to add the script to crontab. To make this work you need to make another script run by cron . try to edit  /etc/rc.local file remove your script there or create an /etc/init.d/ scrip with proper run level to enable at boot run sudo update-rc.d SERVICE-TO-START-AT-BOOT enable . You may need to remove any services you installed from start at boot  (VLC can’t be run as sudo so make sure you’re in the right cron so not use sudo crontab -e ). You may need to add “nice” at the binning of the command so camera do not crash at start up. for mavproxy use (sudo crontab -e ) because runs as root.

sudo nano




sudo chmod +x

crontab -e

add to crontab file this will run the script file at boot

@reboot /home/pi/

Or python script

@reboot python /home/pi/ &

watch the video stream

To watch the video stream, open VLC on a computer on the same network as the raspberry pi you are using for streaming. Press Media -> Open Network stream and paste the following in the field:
