RE: M0138: VOXL FPV ESC - No Current Readings When Calibrating
Hey @Alex-Kushleyev please disregard this. I just read through a post here that mentions the current measurement on the calibration script is not currently working. It also states that M0138 only has current monitoring on
id 2
I will run spin test command below for now to capture current via
id 2
:./voxl-esc-spin.py --id 2 --power 40 --ramp-time 2.0 --timeout 2.5 --enable-plot 1 --cmd-rate 250

M0138: VOXL FPV ESC - No Current Readings When Calibrating
Hello @Alex-Kushleyev I was hoping you could help me figure out why I am not seeing current readings when calibrating the ESC.
SW Setup:
FW Build - m0138_1_v0_39_RC11HW Setup: Connected directly to J1 on the M0138 ESC with a UART adapter to a PC running Ubuntu 22.04. ESC externally powered by batteries.
Issue Summary:
No calibration data is being displayed when running voxl-esc-calibrate.pySteps to Reproduce:
- Connect M0138 to motors, battery and via J1 to a PC with a UART to USB adapter
- Run:
./voxl-esc-calibrate.py --id 0 --pwm-min 10 --pwm-max 95
Actual Results:
Expected Results:
- My expectation for voxl-esc-calibrate.py would be to output the current data after the calibration test.
Questions / Comments:
- I saw some discussion within the forum that for some of the ESCs current sensing is setup for all 4 channels and the output of the current is a total current measurement for all 4 channels. Does the M0138 measure current individually on each channel or as a combined measurement of all 4 channels?
- As a follow up to the last question, I tried to run calibration on each channel individually and did not see any current readings. Is there a way to run the calibration for all motors at once such as the spin test with running id
255
? I attempted to pass this argument and it failed:./voxl-esc-calibrate.py --id 255 --pwm-min 10 --pwm-max 95
- Do I need to configure anything in FW to read current?
Any help would be greatly appreciated!

RE: What connector do you use for integrating a peripheral into MAVLink Instance 1 on TELEM 2?
@Alex-Kushleyev thank you for your response, this answers my question!

What connector do you use for integrating a peripheral into MAVLink Instance 1 on TELEM 2?
Hello,
Looking through your documentation here I found mention of the following:
"MAVLink Instance 1
hard coded to TELEM2 as itβs routed in the PCB, defaulted at 921600 baud in Normal mode
this is the primary serial interface to communicate with VOXL
the baud rate and mode are configurable by the user, but recommended to use the defaults"**I cannot find mention of TELEM2 in any of the documentation for connectors and see that it is routed on the PCB and is the primary serial interface. What is the correct connector on the VOXL Flight for interfacing with TELEM2? Can any UART work, and if so, how would that connector be defined as the interface to route MAVLink messages? **
Thank you very much for your time and any help on this matter.

RE: Does VOXL Flight Support Express LRS?
Express LRS does work via the above wiring on VOXL flight after testing in Q Ground Control

RE: 12V Output Option for Power Module v3
@Vinny thank you so much for the thorough and punctual response!
I will give this rework a shot per your instruction and report back if I have any issues.

RE: VOXL 2 mini w/ Camera Adapter M0076/M0084: Are there any versions that have smaller FR4 / footprints?
@Moderator Thank you for the response.
I did come across this product of yours here: https://www.modalai.com/products/mdk-m0135?_pos=1&_sid=e4d19a51b&_ss=r that should work great after looking through some of your user guides and technical documentation.

Does VOXL Flight Support Express LRS?
Hello,
I am wondering if VOXL Flight can support Express LRS via J1004 - RC input / Spektrum/SBus/USART6 Connector?
Our plan is to pull 5VDC off of J1003 and use G / Tx / Rx from J1004.
Thank you,

12V Output Option for Power Module v3
Hello,
I was wondering if you could provide documentation on what components to swap out on the stock power module to convert the 5VDC to 12VDC? I have a few extras and wanted to rework the PCBA rather than purchase a new one is possible?
From a previous post from @Vinny I see that you mentioned "We have already configured and tested 12V versions of our power module as an FYI.
Thank you,
