Using SIYI Gimbal and Smart RC Controller with VOXL2
-
@Raza-Rizvi We have never attempted to integrate one of these. But I took a look at their documentation and it looks like it connects to the flight controller with 2 interfaces. One is UART for Mavlink which could be connected to an application processor (Linux) UART via one of our add-on boards. And the other is SBus for RC input. This would require one of our M0065 IO boards since we do not support SBus on VOXL2 directly.

M0065 IO boards
Hey Eric,
Thanks a lot for a super quick response.
Can you like me to the add-on board and the IO boards you are mentioning?
-
@Raza-Rizvi Here is an add on board with UART: https://www.modalai.com/collections/voxl-2-add-ons/products/m0151?variant=47083939791152, and here is the M0065 IO board: https://www.modalai.com/collections/expansion-board/products/voxl2-io?variant=40610514206771

@Eric-Katzfey Awesome, thanks.
I'm also buying the VOXL 2 Ethernet and USB Hub Add-on to integrate a Livox Mid 360 lidar on VOXL2. In this case, I wont need to buy an additional Add on board with UART right, since the VOXL 2 Ethernet and USB Hub Add-on also has a UART expansion?
-
@Raza-Rizvi Yes, you should be able to use J9 on that board.

J9
Best.
One more thing, the control input to the gimbal comes from a telem from the flight controller, as can be seen in the image attached.
Which port should I use from the VOXL2 for that purpose?
-
@Raza-Rizvi That one may prove to be more challenging. Is there a PX4 driver that sends commands to it over UART?
-
@Raza-Rizvi In that diagram it shows PWM out to the ESCs. Are you planning to use PWM ESCs or the UART based ModalAI 4-in-1 ESC?
-
@Eric-Katzfey I wanted to know whether we can directly control a gimbal motor using PWM or gimbal control board directly through telem data from voxl 2
-
@Jetson-Nano VOXL 2 does not have PWM out. You would need our IO expander board M0065 to bridge between UART and PWM. https://www.modalai.com/products/voxl2-io?variant=40610514206771
