(The shutter can be removed if unneeded or manually controlled via i2c) Overall it produces better quality images. The shuttered version of the lepton automatically does a flat field correction on power-up and when needed(This calibrates the sensor, reduces noise, and gets rid of the lines reported on some of the sensors).The PCB has the same size and mount holes as the standard raspberry camera.To configure the camera settings you also need an i2c port, although this is not required.To read an image from the lepton module all you need is an SPI port.This board will accept from 3-5V input and regulate it to what the Lepton Module wants.This revolutionary camera core is poised to equip a new generation of mobile and handheld devices, as well as small fixed-mount camera systems, with thermal imaging capabilities never seen before.Lepton contains a breakthrough lens fabricated in wafer form, along with a microbolometer focal plane array (FPA) and advanced thermal image processing.

It packs a resolution of 80 × 60 pixels into a camera body that is smaller than a dime.

The FLIR Lepton™ is the most compact longwave infrared (LWIR) sensor available as an OEM product. This board provides the socket, power supply's, 25Mhz Crystal Oscillator, 100 mill header for use in a breadboard or wiring to any host system such as an ARM based Arduino or a Raspberry Pi. This is a Breakout board for the Lepton Thermal Camera Module. Stock is being refilled, in the meantime you can get the camera and breakout here: What is it?
