When inserting it into the breakout board be sure to use proper personal grounding, such as a grounding wrist strap, to prevent damage the module. The Lepton module is extremely sensitive to electrostatic discharge (ESD). I am trying to use a python program on the raspi to capture raw thermal images from the lepton 3 which i can then process with python and open CV to filter out the pixels in the image which are above a certain temperature. I just got my PT2 + Lepton 3.5 and for my use, I need to stream video from the Raspberry to another device, but I also need to be able to control the. Note: The PureThermal 2 does NOT include a FLIR Lepton imaging module and will need to be purchased separately or in the Dev Kit. I have a flir lepton 3.0 on a pure thermal 2 breakout board connected to a raspberry pi 4b via a micro usb cable. For a secure connection, you could also use solder a custom Raspberry Pi hat using a prototyping board. The PureThermal 2 and GetThermal both support the radiometric mode of Lepton 2.5 & 3.5 and can view Lepton data on x86 Linux and macOS platforms or even on a Raspberry Pi. The rules for this challenge are to use the Flir Lepton 2.5 in radiometric mode using either the Raspberry Pi Zero W or ESP32. Raspberry Pi 3 B+ Starter Kit FLIR Radiometric Lepton Dev Kit Note: To reduce the number of components used, you could wire the thermal camera straight to the Pi using F/F jumper wires. It’s easy to get started with the PureThermal 2 with the open source software application, GetThermal. If USB isn’t neccisarily your desired medium, this board has also been fitted with 0.1" pins to interface over UART or I 2C. With a Lepton inserted into the PureThermal 2 you will be able to achieve 9Hz color video over USB using the USB UVC class. to Flir Lepton Here is another way to connect a Lepton 3.0 or 3.5 to a Raspberry Pi that obviates some of the performance issues when trying to read the VoSPI directly. ![]() For developers, its reference firmware, viewer software, and hardware schematic are all open source!Įach PureThermal 2 is equipped with the reliable STM32F412 ARM microprocessor capable of processing images without any external system inputs. Based on the powerful FLIR Lepton 3.5, this camera was initially designed to detect Asian hornet nests. Each PureThermal 2 ships pre-configured to operate as a plug-and-play UVC 1.0 USB thermal webcam that will work with a standard webcam and video apps on all major platforms. The PureThermal 2 Smart I/O Board is a hackable thermal USB webcam breakout for the FLIR Lepton® thermal imaging camera core.
