Batianda

Batianda TFmini-S 2 in 1 accessory .1-12m 1000Hz UART I2C

SKU CH-T18H-6JTDN

A compact LiDAR distance sensor measuring 0.1 to 12 metres at up to 1000Hz with UART and I2C interfaces

  • Precise ranging with a 10 cm blind zone
  • Real-time detection at 1000 Hz configurable frame rate
  • Dual UART and I2C interfaces for flexible integration
  • Compact 42×15×16 mm module weighing only 5 g
  • Eye-safe 850 nm Class 1 laser with 70 Klux ambient immunity

Purpose and audience

The Batianda TFmini-S is a 2 in 1 accessory that combines a ToF laser radar distance sensor with UART and I2C interfaces. It suits robotics engineers, drone builders and automation integrators who need real-time ranging from .1 to 12 metres. The module is not intended for buyers who require longer detection ranges or multi-point 3D mapping.

Thermals, noise and power

The sensor operates from 0C to 60C with a Class 1 eye-safe 850nm VCSEL and draws minimal power through a 3.3V TTL UART connection. Its 5g mass and 42x15x16mm footprint add negligible thermal load to a Raspberry Pi or industrial PC. No active cooling is required and the solid-state design produces no acoustic noise.

Sustained-load behaviour

At the configurable 1000Hz frame rate the module maintains 6cm accuracy from .1 to 6 metres and 1% accuracy from 6 to 12 metres with 1cm resolution. Strong ambient light immunity up to 70Klux keeps readings stable during continuous outdoor operation. The reduced 10cm blind zone ensures consistent close-range data throughout extended runs.

Questions about this item

How do I wire the TFmini-S to a Raspberry Pi and which step do people often miss?

Connect the module to 5 V power, ground, and either the UART (TTL 3.3 V) or I2C pins; the step many miss is sending the configuration command to switch between UART and I2C modes before reading data.

What part of the sensor will need replacement first in long-term use?

The 850 nm VCSEL laser emitter is the only active optical component; its output gradually declines after extended operation, so the emitter eventually limits the module's useful life.

What limit appears first when the sensor runs continuously at 1000 Hz?

Sustained 1000 Hz operation pushes the internal processor and laser driver to their thermal ceiling in the 0-60 °C range, so temperature rise becomes the first bottleneck before frame-rate or accuracy specs are affected.
