Teledyne Teledyne FLIR Lepton 3.1R Thermal Camera Module, 160×120 LWIR Radiometric

Description

The Teledyne Teledyne FLIR Lepton 3.1R (500-0758-03) is a high-performance, long-wave infrared thermal camera module engineered for embedded vision and IoT sensing. Its 160×120 pixel uncooled microbolometer sensor operates in the 8–14 µm spectral range, capturing detailed thermal imagery with radiometric output for precise per-pixel temperature measurement. The module communicates via a standard SPI interface, simplifying firmware development on platforms like Arduino, ESP-IDF, and Raspberry Pi OS.

Designed for low-power operation, the Lepton 3.1R is suitable for continuous monitoring in battery-powered devices. Its 56° horizontal field of view offers wide-area coverage for applications like industrial equipment monitoring, building automation, and security systems. The module’s OEM-ready compact build allows for direct integration into custom enclosures and PCBs, providing reliable thermal data output for advanced analytics and edge processing.
