Yes, use the normal RC port. But cannot use an SBUS receiver with that port.

Great to hear @mikhail-mayers . I tested the module you sent back and it baffles me... must be some internal silicon damage to the IC since it had all in-spec inputs, and no faults on any outputs, but it was just not turning on... so, it is now one of my Mechanical Samples

Glad we could get that resolved for you and thanks for your patience.

Unfortunately, the M0065 board is supported on ArduPilot only for use with PWM ESCs. There is no support for RC.

Hello @zaimin78 ,

Without any changes, you can have 1 Boson and 3 ov7251 only. I would suggest connecting Boson to J8, so that the mounting tab on the M0181 aligns withe the VOXL2 mounting hole. So you would have:

J6L : slot 0, cci bus 0 : ov7251
J7L : slot 2, cci bus 2 : ov7251
J7U : slot 3, cci bus 3 : ov7251
J8L : slot 4, cci bus 1 : Boson

In order to connect the 4th ov7251 (it would go to J6U, via M0135), you would need a device tree change in the kernel (need a different kernel).

Also I need to double check to see if any other signal routing changes would need to be made (on M0135).. Let me get back to you soon.

@mrawding , I am sorry, but it looks like we are not going to be officially supporting Ubuntu2.0 Kernel on VOXL2, as we are working on enabling next gen hardware.. We did start the effort but it is not going to be finished for the general availability for VOXL2.

@PatkirkMartin,

I will pass on your note about the order to our team.

Regarding DSHOT, can you please clarify which features are a must-have for your application? specifically, do you need both DSHOT control (lets say Dshot600) and DSHOT telemetry? Or UART Telemetry.. or no telemetry..

Thanks,

Alex

Hello @patkirkmartin ,

DShot could be used with VOXL2 when using Flight Core V2 as an external flight controller (stm32-based). However, Flight Core V2 is EOL.

The IO expander board (M0065) does have capable hardware to generate DSHOT signals, however, integrating and testing DShot-based ESCs is not in the scope of our team's effort.

Have you considered using a 3rd party flight controller as well as the ESC and using VOXL2 as a companion computer?

And the latest build of our fork with this fix is here: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.14.0-2.0.146-202607161052_arm64.deb

Here is the PR for upstream PX4: https://github.com/PX4/PX4-Autopilot/pull/27931

This is the commit that I'm planning to propagate: https://github.com/modalai/px4-firmware/commit/c4fd40afc9f0c79a83a633023013f11b1185cf23
