What are the differences between M0125 and M0151? I can't find any references to M0151 in the forums or technical docs.

@Vinny Extremely useful. Thanks Vinny!

Specifically this one

Hi. The technical documentation page is currently blank but I was wondering if the step or sldprt file for the new VOXL 2 Ethernet and USB Hub was readily available. Thanks

@Vinny Thanks for this info this is super helpful. I 100% agree about the last thing you said and if I can use the ModalAI power adapter then I definitely will. I got the 7.4V spec by assuming nominal 2S battery voltage to nominal 6S, which was probably a bad assumption. Even so, a 2S battery from dead to full charge is typically 6.4V to 8.4V so I figured 5V input was probably not sufficient for the power module as it was not in the range of 2S to 6S. Seems like this may not be the case though which is excellent

@Vinny Unfortunately I will not be able to get the 7.4-22V input the ModalAI BEC requires so I'll try the one from the link i sent above. Rated for 4A so it will hopefully suffice

When I plug a camera into J6 on the Voxl 2 Mini, the mounting hole gets partially covered. Is there an ideal mounting solution for this board?

@Vinny The documentation says that the Voxl Mini requires 6A inrush current capability. Is that true? Just looking for alternative BEC's for our system because in our system we only have a 5V and 12S supply at our disposal. Looking at the following component specifically https://www.amazon.com/DSN6000AUD-Converter-Regulator-Photovoltaic-Generation/dp/B09BDXZSRZ

@wilkinsaf google seems to suggest changing a /etc/network/interfaces file may do the trick but this file does not exist in the voxl filesystem

@wilkinsaf Actually it seems these settings don't stick after rebooting the voxl... Any ideas?

@wilkinsaf This worked! Thank you

@wilkinsaf I was just connecting to my laptop for now. Laptop set with a static IP

https://docs.modalai.com/voxl2-mini-shell-access/

The bottom of this doc says "If using wired ethernet, set up a static IP address." but I've tried doing ifconfig eth0 ~ip address~ netmask ~subnet~ to no avail. I've also tried ip addr add xxx.xxx.xxx.xxx/yy dev eth0 to no avail (always sets ip to 169.254.4.1). I know the Voxl 2 wasn't able to have a static ip set so if it is the same for the mini then so be it, the doc just made it seem like it may be possible so I was just curious

@Vinny Thanks Vinny!

@Vinny Thanks Vinny for looking into this! I'm going to do some bench tests knowing this and will let you know how it goes!

If I were to use a USB C breakout board to connect to a USB A ethernet adapter (just a pdb for consolidating space), will the Voxl require a CC resistor on the USB for negotiation? Or could I just use something like this https://www.digikey.com/en/products/detail/adafruit-industries-llc/5180/15287551?utm_adgroup=&utm_source=google&utm_medium=cpc&utm_campaign=PMax Shopping_Product_High ROAS Categories&utm_term=&utm_content=&gclid=Cj0KCQjwtJKqBhCaARIsAN_yS_lTlKOorgebACjn6JgJ4PSgA-ffYGH5xnw3K0EXZeDwTNLaVlZdyCAaAoz2EALw_wcB

I noticed the disclaimer in the docs that stresses the Voxl 2 Mini only gets 3.8V power supply and I just had a couple follow up questions.

1. Can the mini alternatively receive power only through the USB - C port (5V)?

2. Can the mini operate normally on 3.3V (a more standard value)?

3. What is the best way (or any way) that you'd recommend to step down 5V to the required 3.8V? The power adapter provided by ModalAI looks like it would not function on 5V as it requires a minimum of 2S supply?

Thanks!

@tom Oh totally missed that, thanks! Also, do you know if when using that board, one USB can be used for an ethernet adapter and the other can be used for UVC Cameras?

https://docs.modalai.com/5G-Modem-datasheet/#j9-uart--i2c

Can the UART on this board be used for external flight controllers? It looks like its using the QUP13 UART but the M0125 board uses GPIO_22_UART7 on /dev/ttyHS1.

@tom Thanks for the reply. Yea I’ve spent a good while poking around the web page in the past. I’m also not actually connected using a second radio over RF, I have the voxl plugged into the DEV USB of the radio and then my computer plugged into the regular Eth wires of the radio, which could be the issue. If you guys haven’t experienced this tho I can reach out the Doodle too and see if they have any suggestions
