FLIR Lepton 3.0 & 3.5 Micro Thermal Camera Modules

FLIR Lepton 3.0 & 3.5 Micro Thermal Camera Modules

FLIR Lepton 3.0 and 3.5 Micro Thermal Camera Modules offer 160 x 120 active pixels and <50mK thermal sensitivity in a small 11.8mm x 12.7mm x 7.2mm package. The 3.0 module is non-radiometric, while the 3.5 module has a radiometric thermal imaging system. Both modules feature a CCI (I2C-like) control port and video over SPI video data interface. While the 3.5 offers the same size, it also provides calibrated radiometric output across the entire 19,200 pixel array. FLIR Lepton 3.0 and 3.5 Micro Thermal Camera Modules feature low power consumption, unmatched image quality, and simple integration.

FLIR Lepton Camera Breakout Board v2.0

FLIR Lepton Camera Breakout Board v2.0 quickly connects all versions of the FLIR Lepton camera module to common platforms like Raspberry Pi or custom hardware. This easy-to-interface evaluation board provides onboard power supplies, generated from 3V to 5.5V, and a master clock. By using a jumper, the master clock, local power supplies, and power-up sequence components can be bypassed. FLIR Lepton Camera Breakout Board is designed for applications where SWaP, cost, and quality are critical.


  • Space-saving
  • Works with all FLIR Lepton modules
  • Access to SPI and I2C camera module interfaces
  • Dual low-noise LDO
  • Designed for quick prototyping and development, not for production use
