PureThermal Mini Pro JST-SR (with FLIR Lepton 3.5)

The PureThermal Mini Pro JST-SR with Thermal by FLIR is an innovative thermal camera that can be customized to your needs. This product comes ready to use as a plug-and-play UVC 1.0 USB thermal webcam, compatible with standard webcam and video apps on all major platforms. The reference firmware and viewer software are open source, providing a flexible platform for developers.

With multiple connection options, including soldering straight to the board or using a custom cable via the JST-SR port, the PTMini Pro is highly versatile. The product features four mounting holes and less complex circuitry, simplifying the embedding process into a production system. The inclusion of USB DFU further enhances the product's usability.

The PTMini Pro comes with a FLIR Lepton 3.5, a radiometric-capable LWIR camera solution that is smaller than a 10-cent coin. This powerful camera captures accurate, calibrated, and noncontact temperature data in every pixel of each image, making it an invaluable tool for a wide range of applications.
