Laser distance up to 4 m over I²C
The ET-S05 is built around the ST VL53L1X — 940nm laser ToF, up to 4m, up to 50Hz, programmable ROI. It connects over I²C 0x29 (changeable in software at runtime) and is powered from VIN 3.3–5.5V, onboard LDO.
Two Qwiic / STEMMA QT connectors let you chain it with other boards without soldering, and the 2.54 mm header fits a breadboard.
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Obstacle avoidance for robots
- Liquid and bin level sensing
- People counting and presence
