The SparkFun Qwiic dToF Imager TMF8821 is a direct time-of-flight (dToF) sensor that includes a single modular package with an associated Vertical Cavity Surface Emitting Laser (VCSEL) from AMS.
The dToF device is based on a Single Photon Avalanche Photodiode (SPAD), time-to-digital converter (TDC), and histogram technology to achieve a 5000 mm detection range. Due to its lens on the SPAD, it supports 3x3, 4x4, and 3x6 multizone output data and a very wide, dynamically adjustable field of view. A multi-lens array (MLA) inside the package above the VCSEL widens up the FoI (field of illumination).
