Teledyne Teledyne FLIR Lepton UWFOV (500-1387-00) Thermal Camera Module, 160×120 LWIR, 160° HFOV, Radiometric, SPI

The module is designed for seamless integration with popular embedded platforms. It connects directly to Raspberry Pi and BeagleBoard boards using its SPI video port and I2C-like CCI control interface. For microcontroller projects, you can use it with Arduino (via compatible shields) or STM32 using provided driver libraries. Official Teledyne FLIR software development kits (SDKs) and communication protocols are available to streamline image capture and temperature data extraction on your chosen system.

Power the module using its specified voltage rails: 2.8V and 1.2V for the core, and 2.5-3.1V for I/O. A typical setup involves a regulated power supply or LDO. For interfacing, connect the SPI lines (MISO, MOSI, SCLK, CS) to your host controller for video data. The I2C-like CCI port (SDA, SCL) is used for sending configuration commands and reading telemetry. Ensure proper signal level translation if your host operates at 5V logic. Refer to the Teledyne FLIR Lepton Engineering Datasheet for detailed pinout and timing diagrams.

In radiometric mode, the Lepton outputs calibrated data where each pixel value corresponds to a precise temperature, enabling accurate thermal measurement and analysis. Non-radiometric mode provides standard video imagery optimized for display without the computational overhead of temperature calibration. You select the mode via the CCI interface. For applications requiring temperature readings, such as fault detection or environmental monitoring, you must configure and process the module in radiometric mode using Teledyne FLIR's provided algorithms.

The module's housing operates from -10°C to +80°C, while the detector can image scenes from -10°C to +400°C in high-gain mode. Extreme ambient temperatures can affect the sensor's calibration and noise floor. For accurate measurements, allow the module to thermally stabilize after power-on. Teledyne FLIR provides calibration data and software tools to perform periodic non-uniformity corrections (NUC) to maintain accuracy, especially if the housing temperature fluctuates significantly during operation in harsh environments.
