UAV Lightweight Thermal Camera Module
≤40 mK NETD, 640 × 512 VOx LWIR, <8.6 g — ultralight thermal Camera Module module for UAV gimbals, robotics, and mobile platforms.
System Detail
What It Is
The XTM2640LT is an uncooled LWIR thermal imaging Camera Module module using a vanadium oxide focal plane array, classified as an Uncooled LWIR Thermal Camera Module Module optimised for UAV gimbal payloads, FPV drone integration, robotics platforms, and mobile surveillance units requiring minimal payload mass.
Performance
The XTM2640LT delivers thermal sensitivity of ≤40 mK NETD measured at F/1.0 and 25 Hz. The 640 × 512 VOx detector operates across an 8–14 μm LWIR spectral range with a 12 μm pixel pitch and supports frame rates of 30 Hz and 60 Hz on both the sensor and digital video output. Power consumption is ≤0.7 W at 25 °C from a 5 VDC supply. The module weighs under 8.6 g without lens and measures 21 × 21 × 10.3 mm, making it compatible with payload-constrained drone platforms.
Key Technical Features
- Quad digital video output supporting DVP, BT.656, USB, and MIPI CSI simultaneously, alongside analogue PAL/NTSC, with UART, I²C, and USB serial communication for flight controller and embedded processor integration.
- Digital zoom from 1× to 8× in 0.1× steps with shutterless non-uniformity correction algorithm, eliminating the mechanical shutter click cycle that disrupts continuous UAV imaging streams.
- Standard lens at 9.1 mm focal length with optional lenses from 9.1 mm to 55 mm including F/1.0 manual focus options, with iFOV values from 1.3 mrad down to 0.22 mrad for long-range target observation from altitude.
- Built-in electrical protection against over-current, over-voltage, reverse-polarity, and high-voltage surge, with image mirroring in horizontal, vertical, and diagonal axes for flexible gimbal mounting orientations.
Platform Compatibility
The XTM2640LT is designed for integration into UAV gimbal assemblies, FPV racing and surveillance drone platforms, ground robots, and vehicle-mounted mobile surveillance units. The XTM2640LT bare-core module variant targets board-level integration in custom payload enclosures and robotics chassis.
UAV-Optimised Thermal Core
The XTM2640LT uses a 640 × 512 vanadium oxide uncooled focal plane array in a 21 × 21 × 10.3 mm package weighing under 8.6 g without lens. This form factor is sized for direct installation into small UAV gimbal assemblies and FPV drone payload bays without weight penalty.
Quad Digital Video Architecture
The module simultaneously provides DVP, BT.656, USB, and MIPI CSI digital outputs alongside analogue PAL and NTSC, with UART, I²C, and USB serial control. This breadth of interface support eliminates signal conversion overhead when connecting to diverse embedded processors and flight controllers.
Shutterless Non-Uniformity Correction
The XTM2640LT supports a shutterless NUC algorithm in addition to standard shutter-based correction, removing the mechanical correction cycle from the imaging timeline. Continuous NUC delivery maintains calibrated image quality throughout extended airborne missions without interrupting the video stream.
Sub-Watt Power for Long Endurance
Operating at ≤0.7 W from a 5 VDC supply, the XTM2640LT is engineered for battery-powered UAV platforms where thermal budget directly affects flight endurance. The low operating current allows sustained continuous imaging on small lithium-polymer cells without forced cooling.

Designed for the Field
UAV Gimbal and Drone Payload
The XTM2640LT addresses UAV payload weight budgets requiring a full-resolution thermal imaging engine below 10 g without lens.
Robotics and Mobile Platform Integration
The module supports ground robot and mobile surveillance platform integration where low power draw and compact form factor are primary constraints.
OEM Payload and Embedded System Integration
UAV payload manufacturers and robotics OEMs embed the XTM2640LT into custom gimbal housings and embedded vision systems using its quad digital video interface architecture.
UAV Gimbal and FPV Drone Payload
The XTM2640LT serves as the thermal imaging core in UAV gimbal assemblies and FPV drone payload bays where mass and power budgets are the primary integration constraints. A module weighing under 8.6 g and consuming ≤0.7 W at 25 °C fits within the payload envelope of commercial and tactical drones without requiring active cooling or dedicated power regulation circuitry. The 640 × 512 VOx detector delivers ≤40 mK NETD imagery at 30 Hz or 60 Hz frame rates, with MIPI CSI and DVP outputs directly compatible with Raspberry Pi, NVIDIA Jetson, and similar onboard processors used in autonomous surveillance and target detection workflows.
