Raspberry Pi FLIR: A Hackable Thermal Webcam

The PureThermal 3 board is a unique device that works similarly to a USB camera, but requires specific software to visualize the data. For Linux and macOS users, the GetThermal open-source image viewer is a great option. This hackable thermal webcam ships with the low-cost FLIR Lepton FS module and is compatible with FLIR Lepton (2.x - 3.x) LWIR camera core.

One of the key features of the PureThermal 3 board is its versatility. It has a misc section that includes boot and reset buttons, making it easy to troubleshoot and control the device. The board also features a castellated edge with full JTAG breakout for rapid flashing via Tag-Connect EC-10-IDC, allowing users to flash custom firmware using USB DFU.

In terms of I/Os, the PureThermal 3 board has a partially MikroBUS compatible breakout pin configuration with GPIOs, UART, I2C, SPI (3V), +5V (V_IN), +3.3V (+3V), and GND. This makes it easy to integrate with other devices and systems.

The board also features a USB Type-C port with USB UVC, making it compatible with Windows, Linux, Mac, and sometimes Android. This means that users can connect the device to their computer or mobile device and start using it right away.

One of the standout features of the PureThermal 3 board is its micro thermal camera module. It ships with a FLIR Lepton FS non-radiometric 160 x 120 resolution camera module, which provides high-quality thermal imaging capabilities. The board also supports LIR Lepton (2.x - 3.x) LWIR camera cores, making it compatible with a range of different cameras.

The microcontroller used in the PureThermal 3 board is an STMicro STM32F412 Arm Cortex-M4 MCU running at 100 MHz with up to 1024 KB flash and 256 KB SRAM. This provides plenty of processing power for the device's various functions.

Overall, the PureThermal 3 board is a powerful and versatile hackable thermal webcam that offers a range of features and capabilities. Its compatibility with a range of devices and systems makes it a great option for users who want to integrate thermal imaging into their projects.
