PURETHERMAL-3, 500-0771-FS1

Product Description

Upgrade to a Lepton 3.5 for $50! 

PureThermal 3 (PT3) is a hackable thermal webcam for the FLIR Lepton (2.x - 3.x) LWIR camera core. It has the same basic functionality of the PureThermal 2 but with a few changes and additional features. Unlike the PT2, the PT3 does not have pads to install an RF shield and the Tag-Connect TC2030 programming connector is replaced by the Tag-Connect EC-10-IDC.

New Features:

  • USB-C connector
  • Flash custom firmware with USB DFU
  • Castellated edge with full JTAG breakout for rapid flashing
  • Better buttons for Boot and Reset
  • 3x STM32F412CG GPIO pins
    • PC15, PA0, PH1
  • Breakout for SPI to communicate directly with the Lepton
    • SPI bus is 3V with a 56 Ohm series resistor
  • Partially MikroBUS™ compatible breakout pin configuration

Teledyne FLIR Lepton FS

Lepton FS is a non-radiometric 160 x 120 resolution micro thermal camera module with reduced thermal sensitivity, reduced scene dynamic range, and up to 3% inoperable pixels but the lowest price ever for a factory Lepton. These units balance performance and price, enabling monitoring applications where radiometry is not required and pixel-level image information is less important than broad thermal data. With the lowest cost per pixel in the Lepton family, low power consumption, and simple integration, Lepton FS provides integrators an appropriate thermal capability for innovative thermal monitoring products in smart building automation, security, occupancy sensing, and more.

Lepton 3.5 is available as an add-on accessory in the case that Lepton FS does not meet your performance requirements.

Important Information

  • All international customers that are ordering any Thermal Imaging Camera will be required to fill out an End Use Statement document before shipment.Once you place your order we will email you the documents.
  • We can only ship this product with a Lepton to North America, Australia, United Kingdom,and the European Union Countries.Any orders for this product with a Lepton placed in a country other than those will be canceled and refunded. We are sorry for the inconvenience.
  • Number of non-defective pixels shall be >97% Adjacent clusters, rows, columns may contain defective pixels that are not factory corrected and unable to be corrected. 3% of operability failures allowed. Temperature compensation Automatic. Output image independent of camera temperature.
  • Lepton FS units are not guaranteed against any radiometric accuracy and users whom wish to use Lepton FS products for radiometric applications do so at their own risk. Teledyne FLIR and GroupGets will not support questions pertaining to calibrating Lepton FS units.

Tips for integrating Lepton into a Housing

  • Recommended Material
    • PORON®
  • Socket Stack
    • Socket > Lepton > Foam > Window > Enclosure
  • Maximum Force
    • < 1Kg (more force will damage the shutter)
  • The foam must be cut out so that it does not interfere with the mechanical shutter pins.
  • Thickness
    • Depends on the enclosure and spacing, do not exceed 1Kg of force.
