content: I am considering buying a FLIR Lepton with USB interface board so I can use it on my laptop computer. There seem to be 3 such boards available, all from GroupGets. These are PureThermal Mini, PureThermal Mini Pro, and PureThermal 2. Which is the best one to use, and what features does each one have? I'd like a comparison table with the features of each of them, so I can decide which one to buy, yet I can't find any feature comparison on the GroupGets website. If anybody here has experience with these boards, please let me know the difference in features. I want to make sure I get one that will allow me to use the official FLIR Lepton software to put the device into raw mode (get actual raw data, not a pseudo-colored image generated by the camera in RGB mode). I'm not sure all 3 interface boards will support all the USB commands that the official FLIR software will try to send. The software is available athttps://lepton.flir.com/wp-content/uploads/2015/06/LeptonUserApp_1.3.2.msi_.zip

content: I have been looking for a Lepton board that is not too expensive as I cannot justify spending much on that core. I was going to write a post on the various options available but, as you say there, the options are quite limited. I would like a Lepton to composite video and Lepton to USB webcam interface for my needs. I have the Lepton 3 cores already as I have some faulty FLIR ONE G2’s.If you are looking for a cheap LEPTON 2 80 x 60 core for experimentation, there is a chap on eBay UK selling them for £45 each but he offered me one at £30. They are left over from a large project and he has around 100 of them! Without a useful and affordable interface board I am not that interested in them however.The PURE boards appear to be good but still too expensive to justify for a LEPTON project in my opinion. I looked at the PURE web site for more details on the boards but, as you say, such appeared lacking. I suspect there is a Github repository with all the data you are looking for. I have not looked but people are using these boards to there will be a data repository somewhere on the net. The new Mini board has very little detail provided. I suspect it is a size reduced version of the larger board.I will revisit this at the end of this week.Fraser

content: Quote from: GeorgeOfTheJungle on November 06, 2019, 07:42:29 pmRadiometric Lepton 3 is actually called Lepton 3.5.And what you linked to cost WAY more than the Groupgets PureThermal board already populated with a Lepton 3.5. Your recommended priduct costs over $500.Purethermal Mini with Lepton 3.5 costs $318.99Purethermal 2 with Lepton 3.5 costs $354.99Purethermal Mini Pro with Lepton 3.5 costs $378.99All of the Purethermal options for Lepton 3.5 are cheaper than the product you suggested.
