The ToF HAT is a high-precision laser-ranging sensor designed for the M5StickC development platform. Built around the VL53L0X Time-of-Flight module and a 940 nm VCSEL emitter, it delivers fast, accurate distance measurements up to 2 m regardless of target reflectance.

The 940 nm laser is invisible to the human eye and includes internal infrared filters for improved ambient light immunity and cover-glass crosstalk rejection. Communication is via I2C (address 0x29) on GPIO0 (SDA) and GPIO26 (SCL).
