tCam-Mini is a small wireless streaming thermal imaging camera designed by Dan Julio to make it easy to get and use radiometric data from a Flir Lepton 3.5 sensor. Radiometric data includes the temperature of every pixel captured by the Lepton allowing all kinds of interesting thermographic analysis. Of course that data can also be turned into the beautiful false-color images everyone associates with thermal imaging.
tCam-Mini comes with a capable desktop application, running on Linux, Mac OS X and Windows, making it easy-to-use, right out of the box. Custom applications running on any platform can easily communicate with tCam-Mini via a socket interface. Commands and data are transferred as easy-to-parse json strings.
The companion desktop application makes it easy to use the camera and analyze the data from it.
The hardware and firmware design files are available in Dan's Github repository. The firmware is designed to be compiled using Espressif IDF tools and new code can be loaded via the built-in USB Serial port. Precompiled binary files are also provided for easy upgrades.
Development is ongoing with new features and additional software support planned including a python library and web server.
This campaign introduces tCam-Mini and leverages Group Gets manufacturing capability to make tCam-Mini available to thermography enthusiasts everywhere.

Hi Andrew, thanks for the feedback. We love and offer Paypal payments over in our store. It was a design decision however not to use it for pre-orders because of the delayed payment aspect of our platform. There was simply not a good way to handle delayed payments with PayPal 7 years ago, although maybe things have changed. We'll take a look.
Is the board compatible with the older 80x60 lepton modules (not the shuttered ones)? I think I recall reading that the newer ones used the same socket/pinout? if its physically and electrically compatible, I think I could manage any software changes.
Reason: I have an older module in addition to a 3.5. I'd rather risk the older one for poking around engines whenever I could get away with it.
Hi Woodr. I don't have any experience with Leptons other than the 3.5 but, at least, the Engineering Datasheet shows them having the same pinout. The code I wrote isn't compatible with the older 80x60 pixel leptons. All my work has been focused on their higher resolution radiometric sibling, but if you felt comfortable with ESP32 programming, you could take my code and modify the vospi.c and lep_task.c modules to support your lepton. Basically vospi.c would only have to worry about receiving one segment (instead of four) and in lep_task.c you'd want to pixel double the 80x60 image to 160x120 pixels to feed the rest of the pipeline and external supporting software. Also you could take a look at the schematic for the board. All can be found in my github: https://github.com/danjulio/lepton/tree/master/ESP32/tCam-Mini
Fair question and thanks for pinging. We were due to get them from our local fab on Jun 8 but didn't. We should get them this coming week but since today in Sunday, I can't confirm. We will put out an update as soon as we know more on Monday. The good news is that we were able to get all of the parts and they are in manufacturing.
Hello. You can download the desktop application from my website (http://danjuliodesigns.com/products/tcam_mini.html) and it, and the entire design are also available in the github repository (https://github.com/danjulio/lepton) in the ESP32 directory.
