FLIR LEPTON 3.5 Thermal camera with VOXL 2
-
@Jetson-Nano did you ever figure out a solution to this? I'm getting similar imagery. Is this an FFC issue? Running the same breakout board on a raspberry pi produces completely normal imagery.
-
To close the loop here: we solved our issue of seeing lines by providing power to the lepton via one of the 3.3V pins on the voxl2 mini instead of relying on the power pin of J10 on the sparrow board.

Hi @KLindgren
You raise a concern and something I will run by the team, but if you are powering the M0187 at 3.3V directly, you are violating the FLIR specs for the Lepton and our system design constraints.
How are you connecting M0187 to M0188? Maybe your cable is introducing some extra losses giving you a lower than 2.8V supply?
-
@Vinny apologies, I should have clarified we're using this PureThermal breakout board which regulates VIN from 3.3-5V
-
@KLindgren
OK, M0188 will not work with anything other than our M0187.
Thanks for clarifying. -

M0187
Hi @Vinny - I'm guessing the M0187 is your FLIR breakout board? Do you sell these?
-
Hi @jared
Presently they are integrated within certain drones...
https://docs.modalai.com/stinger-vision-datasheet/I can poke the team to see if we can get it listed separately in the near future.

@KLindgren I am also using the same board but my video stream is with high disturbances, i have posted a image above in the chat. could you please share the image from your camera so that i could figure out what is wrong with my setup. Also the details of your setup, it would be of great help.

@Jetson-Nano our images looked the same as yours when providing power to the PureThermal from the sparrow board (m0188) but using a 3.3V from the voxl2 mini fixed the issue and gives us this imagery.
We are using power from the voxl2 mini's J19 and currently working on running 2 leptons with an RGB using the sparrow board.

@KLindgren thank you for reverting back. From which port are you taking the 3.3 V also how did you complete the circuit, the image you provide is confusing with respect to the connections, it would be great if you would provide further details.
-
Thanks @Vinny

@Jetson-Nano Our 2 Leptons are connected as described in this image - though we're using PureThermal boards instead of M0187s for the Leptons. The 3.3V VIN is provided from the VOXL's J19 port via this cable and a "Y" split jumper we've soldered together.
