Product Overview

The PureThermal Mini Pro JST-SR is a powerful, hackable thermal camera development kit designed for the FLIR Lepton thermal imaging core. This board combines plug-and-play simplicity with the advanced, embeddable features that developers need. This kit comes with a pre-installed radiometric FLIR Lepton 3.5, making it one of the fastest and most versatile ways to start streaming thermal data.

Plug-and-Play UVC Thermal Webcam

Right out of the box, the PureThermal Mini Pro comes pre-configured to operate as a UVC 1.0 USB thermal webcam. This means it works instantly with standard webcam and video applications (like OBS, VLC, or even web browsers) on all major platforms, including Windows, Linux, and macOS—no special drivers or software required.

This "JST-SR" version features a locking JST-SR connector, allowing you to use a JST-SR to USB Cable, or your own custom cable, for a more secure and reliable connection than standard USB.

The 'Pro' Advantage

Beyond its base webcam mode, the PureThermal Mini's "Pro" distinction highlights this board's design as a fully hackable development kit, ready to be embedded directly into a production system.

  • Easy Firmware Updates: Features USB DFU (Device Firmware Upgrade) support, making it simple to load new or custom firmware.
  • Fully Hackable: The reference firmware and viewer software are completely open-source, allowing you to have full control over modifying and adapting the board to your specific application.
  • Embeddable Design: The board features four mounting holes and a simplified circuit layout for easy integration into an enclosure or larger system.
  • Flexible Connections: In addition to the JST-SR port, all critical pins are available on 0.1"-spaced headers for soldering or direct connections.

FLIR Lepton 3.5 Sensor Included

This board comes with a fully certified FLIR Lepton 3.5, Long-Wave Infrared (LWIR) camera that is smaller than a dime. The Lepton 3.5 is radiometric-capable, which means it captures accurate, calibrated, and non-contact temperature data for every pixel in its 160x120 image. This allows you to not only see heat but also measure it, making it ideal for applications such as thermal inspection, non-contact temperature monitoring, and machine vision.
