    both the FMU and IO processors have LEDs, so it depends on which ones are flashing

    Just stepped on it this morning : 6DoF inertial measurement unit (IMU), with Machine Learning Core, Finite State Machine
    Nice video showing how to train using the supplied tools

    Hi everyone! :) Is it ok to ask question here? I'm building drone on Raspberry pi 3 and Pixhawk. Question related to calibrating engines and other stuff - can I do calibration using USB gamepad connected to the ground station? I just wanted to know if I really need RC transmitter and receiver, to just calibrate for the first flight.

    @patrykbilka you might have more luck on forums for those types of questions - more dev related in here. however, it’s not considered a good idea until you have everything tested nd tuned: https://discuss.ardupilot.org/t/how-i-can-fly-quad-copter-without-transmitter-and-receiver-using-apm-2-8/26693

    Hi guys ! I'm looking for a drone frame which include indoor protection for drone, like the AR Drone 2.0 for example with its EPP (expanded polypropylene). But I want to manage all the system inside (flight controllers, electronics etc.). I can still make everything by myself, but it will take time (and not sure to succeed well), so if I can avoid it, it would be cool.
    Have you seen similar project, or have models in head to propose ? Thanks in advance !
    (I have found that "Hardware" is the closer topic for this question. But if you think it has to be somewhere else, do not hesitate)

    has anyone seen a back to back comparaison of the different compass/magnetometers compatible with ArduPilot ?
    I am looking for something better than my ''not so reliable'' QMC5883L

    Hi, do you know any good brushless motor at 800kv ?

    @Ozzy33
    You did not mention the size of motor, but I have had good luck with the rcx BE motors, low cost, good balance, look here http://www.myrcmart.com/advanced_search_result.php?search_in_description=1&keywords=be28&osCsid=p9nljaoq1temejpoose3vcc5k6&x=0&y=0

    If your equipment is compatible with DSHOT, no calibration is necessary.

    Does anyone know how to drive BLheli_s ESC with arduino, I test pwm, the motor with no response

    Pretty simple, d/l blhi_suite, then select your arduino board, then flash it, then goto the motors tab and test.

    @Ozzy33 Nice thanks ! I am looking this kind of motors. I am modding them to go underwater for small UAV. But my old model isn't sold anymore

    I was using this one https://hobbyking.com/fr_fr/2213n-800kv-brushless-motor.html so if you know any one similar let me know ! thanks

    @Ozzy33
    @Silvanosky you wont be disappointed with the rcx BE motors if you were happy with that HK motor. I also recommend using BLHeli_S ESC, very smooth, very low stable rpm and reversible (3D mode). Compared to regular airplane or even simonk esc, these are much better imo. I love the RS30A V2, they are tiny, reliable, low cost, if you need 4 you could go with the 4n1. https://www.banggood.com/Racerstar-RS30A-V2-30A-Blheli_S-ESC-OPTO-2-4S-Support-Oneshot42-Multishot-for-FPV-Racer-p-1072073.html?rmmds=search&cur_warehouse=CN

    @Ozzy33 great thanks a lot ! I will try that

    @Ozzy33 great thanks a lot ! I will try that

    your welcome, I use these esc in my quads, I love them, zero desync even at the highest rates the gyro allows, have fun https://www.youtube.com/watch?v=uHoFfpLSb2g&t=2s

    Hello guys - can I ask drone-assembly related question here? I would like to connect Rpi to pixhawk. Decided to use USB(rpi) -> microUSB(pixhawk) with red 5V cable cut. The last thing to cover is powering Rpi. From what I know, to power Rpi I need UBEC 5V - like this one: https://www.modmypi.com/power-1137/hobbywing-5v-3a-ubec-step-down-converter
    What i think: One output goes to Rpi GPIO to power Rpi, then the other side of BEC is connected with Power Distribution Board (that is connected to Lipo) - Did i miss something?
    auturgy
    @auturgy
    What you’ve suggested will work. Personally I’d be using a serial port on the Pixhawk, not USB. Also, powering a Pi over the GPIO bypasses the polyfuse. There are pads on the bottom of the Pi near the micro USB that you can solder 5V to.
    So: I’d do it differently to be more robust, but your way is easier and will probably be fine.

    before hardware goes, I wonder where I can find the latest Rover framework for simulating? Cause the latest Rover has come to 3.5, however i could only find the 2.5 version
    Anyone knows about this~Thanks in advance
    Amilcar Lucas
    @amilcarlucas
    @DaHaiHuha firmware.ardupilot.org should have all you want and need

    Except a good acro mode :(

    @DaHaiHuha
    Thanks, yes it's firmware...

    @DaHaiHuha
    I have been wondered if I could find a way to output a constant 5V and adjust it to lower electric lever like 1v from main out pin or Aux pin in Pixhawk(using rover), already check the docs and find out I can use main out to output PWM or Aux to output an instant high/low level, they will act as a signal for controling other equipments,

    @khancyr are you aware that DJI might release a ROVER today ?
    patrickpoirier51
    @patrickpoirier51
    The DJI rover stuff. Not actually new, just hasn’t been marketed to consumers before
    patrickpoirier51
    @patrickpoirier51
    Interesting, they will start to sell parts
    Hopefuly with some "openess" of the underlying protocols ;-)

    Hello all, just curious if anybody knows if the RPLidar A2 can be used for obstacle avoidance with the current version of rover?
    I noticed in the docs that dodge does not work with the 360 degree lidars and I was hoping to be able to use it for obstacle avoidance on a survey type mission.

    @amilcarlucas
    Yes, it can with a PR from Tom Pittinger

    If I am having hardware issues with an RFD900x where should I post?
    bj-neilson
    @bj-neilson
    @TunaLobster what sort of issue? I briefly experienced one of those. Was a poor connection on the radio end of the cable from my Cube. Ensure the radio has sufficient power (not from Cube) as a start.

    @OXINARF
    @TunaLobster You should contact the store/manufacturer.

    My issue turned out to be from the Windows serial mouse driver activating when it saw the mavlink data. Kind of odd, but it makes sense. Andras helped me out on the forum.
