      Question from user:

      "I have Modal AI V2 with two of your pcb boards, I intend to use micro hard PMDDL2450 with them. My issue sis when I put the slave unit together with the pcb board and plug it into the computer, the USB drive shows code 10 and doesn't recognize the USB! Do I need any drivers? What can the issue be? The master unit is the voxl drone already. Please help"

        We believe you have a Microhard add-on plugged into a VOXL 2. If this is the case, the Microhard should be providing an IP connection to the VOXL 2's CPU.

        It sounds like you might be trying to use VOXL 2 as an IP tether? That isn't something we support. If you want a USB dongle as tether, you don't need a VOXL 2. You can use this Microhard USB dongle here: https://www.modalai.com/products/mdk-m0048-2

                        @aimseis You likely have to install a LAN7500 driver on your windows machine

                            @aimseis We can only really help with support on linux, I specifically recommend with Ubuntu 22.04.

                                1. The voxl-modem service doesn't need to keep running for the entire time. All it does is a run a few initialization steps and then exits, so that's not an issue.

                                2. I'll get someone from the hardware team to comment

                                  Per Microhard the ABS max of the 5V rail is +10% consistent with USB specs, so 5.5V.
                                  Anything above that will risk damage to your device.
                                  There are other components on our M0048 design that will be damaged at 6V.

                                  What voltage did you apply to this board @aimseis ?

                                        Hi @aimseis
                                        When you use a plug-in board with Voxl or Voxl2, they and the plug-in board manage the input 5V and other voltages so all you need is to provide the correct power module to your Voxl or Voxl2, and the rest is handled.

                                        I'm not able to provide answers on shipping time as I am in Hardware Engineering, not shipping/production. Sorry.

                                            @aimseis Are you able to ping the voxl from your pc over the Microhard network?
