Hello, I'll keep it simple. I'm just attempting to get the motors spinning at this point. Here is what I have and what I'm seeing. 

**Hardware:**

![wiring diagram.jpg](https://forum.modalai.com/assets/uploads/files/1704993055265-wiring-diagram.jpg) 

As you can see from the wiring this is my component list

* Voxl2 
* 4in1 ESC
* Expander Board
* Power Module
* USB Expansion
* USB adapter for Wifi antenna
* Four T-Motor F90 motors 

**Software:**
* QGroundControl Version 4.3
* Voxl
    * System-image 1.7.1
    * Kernel 4.19.125
    * hw version m0054
    * voxl-suite 1.1.0
    * Packages
        * voxl-px4 1.14.0-2.0.55

If you need any other version information, let me know and I'll update the OP. 

I believe I have the VOXL2 configured for proper communication. If I run *voxl-inspect-services*, the following services are active. 

* voxl-cpu-monitor    Enabled    Running
* voxl-imu-server       Enabled    Running
* voxl-mavlink-server Enabled    Running
* voxl-portal               Enabled    Running
* voxl-px4                   Enabled    Running
* voxl-softap               Enabled    Running
* voxl-vision-hub        Enabled    Running
* voxl-wait-for-fs         Enabled    Running

When I run *voxl-inspect-mavlink mavlink_to_gcs* I see heartbeat and other informations update rates. 

**QGroundControl:**
* Airframe - Quadrotor x
* Vehicle - Generic Quadcopter
* Firmware v. - 1.14.0
* CustomerFW ver. - 2.0.55
* Sensors:
        * Gryo - Check
        *  Accelerometer - Check
        *  Level Horizon - Check
        * Compas - Failed: No Mags found
* Actuators Setup
        * Configuration - VOXL ESC

I've worked through the Voxl Dev Bootcamp. I've also used the following links for reference. 
[Modalai: Using VOXL ESCs with PX4](https://docs.modalai.com/modal-esc-px4-user-guide/)
[PXF: Modalai VOXL 2](https://docs.px4.io/main/en/flight_controller/modalai_voxl_2.html)

Any help would be much appreciated.

@mascenzi , with ModalAI ESC you don't need the M0065 expander. You need to connect the ESC J2 (6-pin Hirose connector) to VOXL2 J18 (4-pin JST GH) using MCBL-00029 : https://www.modalai.com/collections/cables-1/products/mcbl-00029 . Communication between ESC and Voxl2 will happen using UART.

@Alex-Kushleyev thank you so much for reaching out with support. I had to tear down the voxl2 setup and build out a pixhawk unit so I could complete thrust testing for our initial frame design. I will get the voxl2 model back up and running and test out your configuration. I actually don't think we have that cable. I'll have to put in order in for it. I'll post back with verification once I have the result.
