Hi @george-kollamkulam
The "Dongle" is standalone and can be paired with any system with USB and 5V.
The "add-on" specifically plugs into VOXL 2 B2B connectors.
This info may help you to better understand our Add-on boards:

Hi @18257581
Sometimes our newer boards are lacking in full documentation, so thanks for your patience.
We have not publicly posted our uCoax pinouts and not sure yet if we plan to. For now it is required to use our full solution which is host adapters, cables, and sensor boards.
I'll bring it to the team. But, we are unlikely to open this up since in order for us to test the components, which are very fragile, they need to be bundled together and not separated, so it would actually cost us more (costing our customers more) to test units individually for customer designs.
Only the Coax cable we sell individually and that is pinned 1:1 with all 26 conductors present unlike some of the other COTS FPV systems.
However, for JST and other cable-to-board and board-to-board connectors, yes, we need to get that listed.
The pinout on J4 of M0201 (the replacement for M0153) is in the same Dronecode inspired format we use at ModalAI for UART + I2C, but in this case since it is not UART, it is 2 GPIOS.
So,
Pin 1 = 3.3V
Pin 2 = GPIO_1 (Undefined/Unavailable/Reserved for Future Use)
Pin 3 = GPIO_2 (Undefined/Unavailable/Reserved for Future Use)
Pin 4 = GIMBAL_I2C_SDA (3.3V Logic Levels, 2.2K pull-up resistor present)
Pin 5 = GIMBAL_I2C_SCL (3.3V Logic Levels, 2.2K pull-up resistor present)
Pin 6 = GND
Thanks @aheyne for alerting us.
I had made the updates to our site and the 3D models are now there.
Let us know if you need any more help.
Thanks!
@mkriesel This cable will help if you do not already have one: https://docs.modalai.com/cable-datasheets/#mcbl-00091
Quick Edit/add: I just noticed our team never had these listed on our shopify site, so they are adding them soon! Thanks!
HI @Jetson-Nano
Yes, absolutely. That was the way we designed it. Some customers need a mounting point, others do not care.
We refer to it as "M0178" when the mounting hole is present, and "M0171" when it is removed, hence the double markings.
The edge there is v-scored, so just gently use a small pair of pliers or strong tweezers to remove that semi-circle, and check for burs (frays/splinters of laminate) and gently smooth it with any ESD safe method like a Kim-wipe or anything you have.
Thanks!
@Sam-Kiley , yes, every Starling 2 / MAX is going to have M0173 board installed and needs to use the option 1.

@mkriesel , you should try to communicate with the ESC from a linux PC using a serial to usb adapter and voxl-esc tools. This will remove VOXL2 from the loop and allow you to test the ESC independently.
It seems there may be some intermittent issue, since you are saying that sometimes you are able to manually spin. what about voxl-esc-scan.py ? Check UART cable?

@psafi the html file is saved in the same folder where you run voxl-esc-spin* scripts if you have --enable-plot 1 . on VOXL2, the plot wont show up on screen, since there is no screen attached to VOXL2 (which would work on a linux pc), but it will be saved to html. In order to save to html, you will need to have plotly installed. You may first need to install pip3
apt update
apt install python3-pip
pip3 install plotly --upgrade

Hello All - I will be trying to recraete this issue in the coming days - will keep you all posted.
From your post i see that you are using the Linux Kernel that is configured for camera front end M0173. I can tell this from mach.var: 1.0.1 in your voxl-version output above.
You need to re-install your SDK and make sure to select the kernel option. You will need to select option 0. See the following thread for more details, however the that user's issue was the opposite - they had 1.0.0 and needed 1.0.1. You need 1.0.0.
