## Description

Designed for FLIR Lepton Longwave Infrared (LWIR) camera cores, this board turns a compatible Lepton into a hackable thermal webcam module. It ships preconfigured as a plug-and-play UVC 1.0 USB thermal webcam for standard webcam apps, including VLC Media Player on PC, Linux, Mac and Android.The onboard STM32F412 ARM microprocessor can process images without external system inputs. With a Lepton fitted, the board can deliver 9Hz colour video over USB using the USB UVC class, and it can be powered from USB-C or VIN.For hardware development, the PureThermal 3 breaks out UART, I2C and GPIO via standard 0.1 inch holes. Reference firmware, viewer software and the hardware schematic are open source, with DFU over USB and JTAG debugging options supported.Note: A FLIR Lepton imaging module is not included and must be purchased separately. Lepton modules are extremely sensitive to electrostatic discharge (ESD), so use proper personal grounding such as a grounding wrist strap when inserting the module.Features:Power: Powered via USB-C or VINUSB thermal video: Get thermal video over USB right out of the box using freeware apps like VLC on Mac, Linux, Windows, or AndroidUSB UVC output: 9 Hz colour video over USB using the USB UVC classProcessor: STM32F412 ARM microprocessor.
