The FLIR Lepton® 2.0 camera core is a long-wave infrared (LWIR) thermal imaging breakthrough in size, power consumption, and price. It currently packs a resolution of 80x60 pixels into a 8.5 x 11.7 x 5.6 mm package that draws only 150 mW nominally. The frame rate is 9 Hz at a spectral response wavelength range of 8 - 14 microns (nominal) and it can be purchased for under $200 in single quantities. Lepton 2.0 is the same thermal imager inside of the first generation FLIR One and the CAT S60 Rugged Smartphone. The new Lepton 3.0 with twice the resolution is available now in our store. Looking for a radiometric Lepton? The Lepton 2.5 is the only radiometric Lepton core available at this time.

The FLIR Lepton is enabling new innovations in industry, science, smartphones, and medicine worldwide. We are proud to have enabled thousands of developers worldwide by being first to make Lepton available in sub-1000 quantities in 2014. We also aim to lower its technical barrier of entry with our custom hardware and open-source software and firmware. Below is a thermal image from Lepton using our latest, the PureThermal 1 FLIR Lepton Smart I/O Module, a hackable USB thermal webcam.
Why use a thermal imager?
Contactless temperature measurement over relatively long distances
Human or animal presence detection in day or night
Finding hot spots on circuit boards without burning your finger (our favorite)
Human position detection in day or night with more privacy offered than a daylight camera (you don't see EVERY detail)
Gesture recognition for contactless control in apps like gaming and smart homes
Human vs. robot detection
Disease and distress detection
Search, rescue, and collision avoidance with UAV/UAS and robotics platforms
The list above barely scratches the surface of Lepton's potential which is what makes this product special. This technology used to only be available at 10x the cost and in larger package size, heavier weight, and greater power consumption making it not suitable for low-cost and portable solutions.
50 degree Lepton DOF/Distance test
The FLIR Lepton 2.0 currently comes in three major variants:
50˚ HFOV with shutter and automatic flat-field correction (FFC) ideal for low-noise images especially with static scenes

Development Tools and Accessories
GetLab has designed multiple useful accessories for Lepton applications and development such as the classic lepton breakout board that makes Lepton's digital interfaces easily accessible and the PureThermal 1 FLIR Lepton Smart I/O Module (PT1) that takes Lepton development to a higher level with multiple I/O paths to command, control, and view Lepton imagery. We've also developed a plug-and-play Raspberry Pi 3 kit that allows you to overlay thermal images over the 8MP PiCam daylight images in real time. The kit has a custom (open-source) test program developed with our "pylepton" python library pre-installed to get you quickly up and running quickly. You can download and learn more about our pylepton library to make your own Lepton applications on the kit at our Github link below.
-In order to do do radiometry with the Radiometric FLIR Lepton 2.5, Y16 firmware is required. Y16 firmware requires specialized software to work such as GetThermal.
-For those wishing to apply possible future updates or load custom firmware themselves, we created a JTAG adapter board which can be purchased here. This adapter will also allow you to do more advanced debugging of PT1 along with faster flashing. Please note that firmware upgrades through DFU mode do not work reliably and are no longer supported on the PT1.
