Input Supply Voltage: 2.8 V, 1.2 V, 2.5 V to 3.Sensor Technology: Uncooled VOx microbolometer.Thermal Imaging Cameras FLIR T865 W/ 42 Lens, 640x480, -40 C to +2000 C, w/FLIR Thermal Studio Pro - 3 Month Subscription + FLIR Route Creator Plugin for Thermal Studio Pro - 3 Month Subscription. Non-Uniformity Correction (NUC): Automatic with shutter Teledyne FLIR Lepton: Thermal Imaging Cameras Lepton 3.5, 160x120, 56 degree, radiometric, with shutter.Image Optimization: Factory configured and fully automated.Array format: 80 × 60, progressive scan.Optimum Temperature Range: -10☌ to +80☌.Non-Operating Temperature Range: -40 ☌ to +80 ☌.Mechanical Interface: 32–pin socket interface to standard Molex® socket.Package Dimensions - Socket Version (w x l x h): 11.8 x 12.7 x 7.2 mm.Control Port: CCI (I2C-like), CMOS IO Voltage Levels.Output image independent of camera temperature. Spectral Range: Longwave infrared, 8 µm to 14 µm.Scene Dynamic Range: -10-140 ☌ (high gain) up to 450☌ (low gain) typical.Radiometric Accuracy: High gain: Greater of +/- 5☌ or 5% (typical) Low gain: Greater of +/- 10☌ or 10% (typical).Output Format: User-selectable 14-bit, 8-bit (AGC applied), or 24-bit RGB (AGC and colorization applied).Input Clock: 25-MHz nominal, CMOS IO Voltage Levels.Effective Frame Rate: 8.6 Hz (commercial application exportable).The radiometric Lepton captures accurate, calibrated, and non-contact temperature data in every pixel. With a focal plane array of 80圆0 active pixels, this Lepton easily integrates into native mobile-devices and other electronics as an IR sensor or thermal image sensor. There are a few private utility functions to start/end transfers, reset the camera and read various amounts of data.The FLIR Lepton® 2.5 - Thermal Imaging Module is a radiometric-capable long wave infrared (LWIR) camera solution that is smaller than a dime, fits inside a smartphone, and is less expensive than traditional IR cameras. The implementation of this driver is simple. It is certainly possible to refactor this code and not buffer the entire frame. Rear System Overview and Second Camera (future project ])Īllocating a FrameBuffer as part of the Lepton_t struct was a decision I made to keep the driver self-contained. The Lepton module can be ripped out the Flir One iPhone accessory for now. ![]() You can pick up one from Tindie if you are interested. I am using a breakout board provided by Pure Engineering. This setup is running at 21MHz with no issues. I have used some simple jumper wires to interface with this camera. I have implemented my own colorization and min/max scaling before uploading the frames to the GPU. ![]() Attached to it is a Gameduino 2 which incorporates the FT800 graphics processor. This is all running on an STM32F4 processor on a Nucleo board. I have successfully implemented a driver for the Lepton module and displayed frames on an LCD. The resolution is 80圆0 at 14bpp which is remarkable despite sounding low. ![]() The footprint of the camera module (and optical assembly) is about the size of a dime. These are absolutely incredible devices that I believe will pave the way to consumer devices incorporating thermal imaging cameras. I recently got my hands on a pair of Flir Lepton thermal imaging sensors and have spent the last week bringing them online in my spare time.
