PureThermal 3 by GetLab

Description

PureThermal 3 (PT3) is a hackable thermal webcam for the FLIR Lepton (2.x - 3.x and FS) LWIR camera core. It has the same basic functionality of the PureThermal 2 but with a few changes and additional features. Unlike the PT2, the PT3 does not have pads to install an RF shield and the Tag-Connect TC2030 programming connector is replaced by the Tag-Connect EC-10-IDC.

Design, PCB Fabrication, and Assembly Done in the USA!

New Features:

• USB-C connector
• Flash custom firmware with USB DFU
• Castellated edge with full JTAG breakout for rapid flashing
• Works with Tag-Connect EC-10-IDC
• Better buttons for Boot and Reset


• 3x STM32F412CG GPIO pins




• PC15, PA0, PH1




• Breakout for SPI to communicate directly with the Lepton




• SPI bus is 3V with a 56 Ohm series resistor




• Partially MikroBUS™ compatible breakout pin configuration




• See the mikroBUS™ standard PDF.


• +5V is V_IN and +3.3V is +3V on PureThermal 3

Features:

• STM32F412 ARM microprocessor: Execute on-board image processing without the need for an external system or SBC.


• USB UVC works on Windows, Linux, Mac, and sometimes Android


• Open source reference firmware is on the GroupGets Github


• Open source reference image viewer software for Linux and macOS


• USB-C connector


• Flash custom firmware with USB DFU


• Castellated edge with full JTAG breakout for rapid flashing


• Better buttons for Boot and Reset
