      @Alex-Kushleyev I found that buying an off-the-shelf raspberry pi heatsink that is 14mm x 10mm (meant for the RAM chip) and combining with a fan works great for the underside of the SIP (on the opposite side of where the main board joins the Ethernet/USB board. Brought my temps down by at least 10-20 degrees even under intense load.

      Hi @joseph-vale , i tested the python script from FLIR help site (Radiometry.py). I just had to modify it to use the correct USB and Video devices. The script ran find, but since my Boson does not support radiometric output, the reported temperature was like 70 degrees colder than it should be (reporting -50C at room temperature). Are you able to get correct temperatures with your device using this script?

      As i mentioned before, there is a way of getting the image data from voxl-camera-server into python. I think it would be interesting to try running the same exact conversion and annotation code from the FLIR example. This would allow you to first check the temperatures using a USB connection and then check them using the VOXL2 pipeline.

      I am going to set up an example that that uses pympa (python wrapper for MPA) to get the 16bit data from Boson and plot + convert it to temperature using the reference code.
