Overview

The Yahboom TinyF is a high-precision laser ranging module (single-point ToF distance sensor) designed for fast distance measurement in compact robotics and UAV projects. It uses a Time of Flight (ToF) ranging principle and supports a 2–400 cm measurement range (20–4000 mm), with measurement accuracy within ±3% and ambient light immunity up to 190 kLux.

Key Features

ToF distance measurement principle; millimeter-level measurement accuracy (test data table provided below).
Detection distance: 20 mm to 4000 mm (2–400 cm / 4 m max).
Frame rate: 30 Hz to 90 Hz (default 30 Hz; 30 data sets per second).
Ambient light immunity: 0 to 190 kLux (supports distance measurement outdoors under strong light).
UART serial communication; compatible with mainstream development boards (Raspberry Pi, JETSON, RDK series, MSPM0, STM32, ESP32, AR, micro:bit).
Compact housing with screw-mounting holes for integration on robot cars, robots, and drones.
Development materials are provided for Raspberry Pi, JETSON, RDK series, MSPM0, STM32, ESP32, AR, and micro:bit.
3D model files will be provided.
