    Hi @nshahrestani Our power modules provide the needed voltage and current demands of both Voxl and Voxl2 (and a new version for V2-Mini). It is a well tested and proven design, so please make sure you still have one in your collection to compare against should you have any issues with your own design. We've had some customers make their own smaller modules, and they experienced issues with power in the system. For Voxl2, we expect 5V +/- 5% to keep the eFuse happy. We have our power module set for 5.08V at no-load to help compensate for any cable drops. You also must have up to 6A of in-rush support during power-on. The steady-state depends on your applications and whether or not you use any plug-in boards (5G modem, Microhard, etc), but we easily can see over 2-3A continuous. However, if you design with a 3A DC/DC, you will likely not be able to boot the system due to power on in-rush. Power is one area you cannot cut corners with, so please use a 6A device for success, and have at least 188uF of bulk capacitance (qty-4 47uF for example) to match our power module performance. Hope that helps.
  • Send Motion Capture System pose data to PX4

    Alright, solved it. I adjusted the MCS pose rate to be at 30 Hz (should be fine up to 50 Hz according to PX4 documentation), although this does not seem to have any significant impact. The problem was that the EKF2_AID_MASK must be set to 24 (only position and yaw fusion) for motion capture, instead of 280 (default with VIO, which sends odometry messages including velocities). Hence the following fields must be set as follows: ... vision position fusion vision yaw fusion ... vision velocity fusion <-- Disable for Motion Capture (enabled by default for VIO) I did not have to modify any other parameters. @James-Strawson, thanks again for the help!

    Nothing, it's totally vanilla VOXL2. Our code is all user space python we run manually, and this thing hasn't run really since the beginning so it has the minimum. Also this time I ran Voxl-inspect-cpu every so often and it shows the processors all running in the 500-800 mhz range nothing being warm.

    @olearypa I just tried and it worked for me but that doesn't mean others aren't having the same issue. I'll send you an email.

    That is really a function of the flight controller. PX4 1.14 will supposedly have this capability. We'll explore how well it works once a stable build is released

    @Alex-Gardner I am trying to get the C270 uvc camera to record its video or frames to the Seeker's onboard SD card. I have not had any luck using Gstreamer for this. Has this been successfully done with the voxl-record-video command from the dev branch? If so, how would I go about getting this to work?

    @Andrew-Yingst You'll want to use a combo of MCBL-0010(https://www.modalai.com/collections/cables-1/products/mcbl-00010) and a USB-A to micro-usb(example: https://www.amazon.com/Charger-USB-Adapter-Replacement-Charging/dp/B08CBDZM6L/ref=sr_1_11?keywords=micro+usb+cable&qid=1682534177&sr=8-11) MCBL-0010 plugs in to the "USB to host PC" connector on the bottom of the standalone board. The micro-usb cable plugs into MCBL-0010 and the other end plugs into your PC. [image: 1682533795941-c05d0fa4-b23f-48d1-8969-d4f32e70103e-image.png] Your PC will then see a new network interface come up. Once it assigns an IP address you should be able to ping the microhard modem (192.168.168.1). Next, navigate to that IP in your browser and you'll be able to access the web server

    @KevinChan 0.9.5 is the newest, 0.9 is second newest, 1.3.1-0.8 (0.8) is super old. We changed our naming scheme some time ago so I can understand the confusion

    That is not really possible, there are too many interdependencies
