TFMini-S — description and specs

TFMini-S technical specs: 12 m range, 100 Hz, UART.

TFMini-S is the older cousin of the TF-Luna in the Benewake family. Similar protocol, similar pinout, slightly different range envelope.

Spec card

Spec	Value
Range	0.1 – 12 m
Accuracy	±6 cm typical
Frame rate	100 Hz
Field of view	2°
Interface	UART 115200 baud
Power	5 V, ~140 mA
Frame format	9-byte packet (different fields from TF-Luna A03 — see datasheet pitfalls)

Differences from the TF-Luna:

Longer range (12 m vs 8 m).
Higher current draw (140 mA vs 70 mA).
Different frame field layout — fields 4-7 in TFMini are str_L str_H res mode, while in TF-Luna A03 they’re Amp_L Amp_H Temp_L Temp_H. The driver code needs to know which it’s parsing.
