Do you see what we see? With the FLIR Radiometric Lepton® Dev Kit you will be able to bring FLIR's thermal imaging reliability and power to your Arduino, Raspberry Pi, or any ARM based development tool all in an easy to access breadboard friendly package. This kit includes a breakout as well as the Lepton® 2.5 longwave infrared (LWIR) imager. All you need to do to get this kit set up, simply attach the Lepton® imager module into the provided breakout, connect the headers, and you will be seeing in full darkness in no time!
The Radiometric Lepton® LWIR module included in each Dev Kit acts as a sort of camera and packs a resolution of 80 × 60 active pixels into a camera body that is smaller than a dime and captures infrared radiation input in its nominal response wavelength band (from 8 to 14 microns) and outputs a uniform thermal image. The Lepton 2.5 can output a factory-calibrated temperature value for all 4800 pixels in a frame irrespective of the camera temperature with an accuracy of +/-5˚C. Meanwhile, each breakout board in these kits provides the socket for the Lepton, power supply's, 25Mhz Crystal Oscillator, 100 mil header for use in a breadboard or wiring to any host system. A few things to consider about this kit: the breakout board will accept a 3-5V input and regulate it to what the Lepton® wants, to read an image from the lepton module all you need is an SPI port, and to configure the camera settings you also need an I2C port, although this is not required.
Note: This kit comes in two separate parts and will need to be assembled once received. The Radiometric Lepton module is extremely sensitive to electrostatic discharge (ESD). When inserting it into the breakout board be sure to use proper personal grounding, such as a grounding wrist strap, to prevent damage the module.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Really cool and easy to use for prototyping thermal imaging applications, but the resolution is too low to capture details, however, it's still quite handy and fun.
Followed the instructions and got things working after some painful digging into the specs. Would not work as shown in the hook up guide. Had to change the CS location to the one mentioned in the github info. Even the github info shows CS attached to the wrong place in the pictures, but the text will guide you to success. Mine had to be on CE0 (pin across from CLK). Anyway after wasting hours trouble shooting It is running great now. Thanks sparkfun..keep the cool products coming!!!!
I bought the kit for a home system, to watch over objects and plants. Everything works fine, and very easy to interface with. Cabling is straightforward and interacting is simple with the available libraries.
The sensor itself feels of very good quality (hence the price), and the images produced are really usable---I did not know what to expect from a 80x60 matrix. Sensing is a bit slow to my taste but it just works fine.
My working settings: * Raspberry Pi 3 Model B+ * Connected on SPI 0 * Interfacing code in Python, using the pylepton library.
If you opt for pylepton, please be careful with what version of the FLIR you get. This is a LEPTON 2.5 and works out of the box with pylepton. I also have a LEPTON 3.5, and we need to use a specific version of pylepton (from the source code, branch lepton3-dev). I lost so much time on that one---hope you don't.
