FLIR LEPTON 3.5 Thermal camera with VOXL 2

[Jetson Nano]

Hello @Alex-Kushleyev @modaltb @Eric-Katzfey

I would like to know whether I could connect a Flir Lepton 3.5 camera to VOXL 2 board. Using the Starling 2 Image Sensor Micro-coax Front-end Adapter board link.
I want to stream the video from the camera through RTSP protocol, is it possible.
VOXL 2 - D0014 Architecture (Starling 2)
here it is mentioned about the flir lepton , I would like to know whether I can stream the lepton Thermal camera data as RTSP stream from this connection.

Hello @modaltb @Alex-Kushleyev @Vinny @Eric-Katzfey
I am using VOXL2, with m0173-1-04 camera board, which has port for lepton thermal camera. there is no documentation available for the m0173-1-04 board , is there any pinout difference

voxl-configure-camera is 29
Flir Lepton 3.5
while I run the voxl-lepton-server command I am getting the following error. can anyone help me with the process. I tried with different configurations, but the error is the same, I2C connection issue. can anyone guide me in the right direction.

@Jetson-Nano , I just tested this and it's working. You may have an issue with pinout, please check https://docs.modalai.com/M0173/#j6---sm08b-srss-tb

@Alex-Kushleyev Thank you for reverting back.
I am using custom Board for the Lepton, with MCBL-00105-02 cable for the connection. I will verify the pinouts.
I checked the camera with different board and it is working now.

Hi @Alex-Kushleyev @modaltb @Eric-Katzfey
I still have the same error when i use my custom board. Could you verify my board pinouts.
