PureThermal Mini - FLIR Lepton Smart I/O Module with Lepton 3.0
GroupGets, FLIR
Mfr. Part #
PURETHERMAL-M, 500-0726-01
Product Description

PureThermal Mini is the world's smallest hackable thermal webcam for the FLIR Lepton (2.x - 3.x) LWIR camera core. It is the result of listening to our thousands of PureThermal 1 & 2 users and giving them what they want: four mounting holes, less complex circuitry, and perhaps best of all, USB DFU. That's right, a JTAG breakout board will no longer be required to update the board. This is a development kit ready to be embedded into a production system.



  • Get Thermal video over USB right out of the box using common apps like VLC Media Player on Mac, Linux, PC, or even Android (see video below).
  • Power Input, Video Output, and Firmware Updates All Over USB (micro B type connector)
  • Compatible with all production FLIR Leptons, including radiometric 2.5 and 3.5 cores
  • Use one standard and included USB type A to micro B cable cable for all major functions

    Is there any way to get the module with the 3.5? The extended thermal range is of interest, thanks!
