The TFA300 series includes the ultra-light TFA300-L without housing version and the TFA300 with IP67 protective housing. Both models feature a high frequency of up to 10,000 Hz. In applications such as Electro optical/infrared (EO/IR) Gimbals, SAR（search and rescue）Drone, and Utra High-speed FPV racing Drone, the TFA300 series facilitates camera focal distance auto-adjustment, precise localization, stable altitude maintenance during cruise, and obstacle avoidance during high-speed flight.
The TFA300 series defaults to 1 ~ 1,000Hz and can be adjusted to 10,000 Hz under ultra-high frequency working mode. It collects data at 10,000 times per second, detecting objects at Mach 1 with real-time distance updates every 3.4 cm. This allows for faster obstacle detection and quicker distance updates, giving drones more time to react.
The TFA300-L weighs 10.5 g with a size comparable to dual stacked dice, while the IP67-rated TFA300 housing adds protective durability at 34.5 g. The series' compact form factor enables direct integration into EO/IR gimbals, achieving SWaP-C (Size, Weight, Power, and Cost) optimization.
TFA300 series uses industry-standard JST GH connectors for direct connection to flight control platform without adapters, featuring a CAN interface for next-gen flight control architectures. With an SDK supporting the DroneCAN protocol, it offers plug-and-play compatibility with mainstream flight controllers, significantly reducing development time and deployment costs.
TFA300 series is fully optimized for complex drone applications, including operation under extreme temperatures, 100 KLux ambient light, and harsh outdoor conditions such as rain, fog, and dust. It effectively resolves frequent false dection issues common in conventional LiDAR systems. To date, this technology has enabled delivery drone customers to achieve over 400,000 accident-free package deliveries globally.
