DNG-TOF20 Eicut Distance Module Description
DNG-TOF20 (also referred to as TOF20) is a miniaturized direct Time-of-Flight (dToF) optoelectronic distance measurement module. It utilizes VCSEL laser technology and a high-sensitivity SPAD detector to achieve precise ranging up to 20 meters. The module supports both UART and I²C interfaces, offers high ambient light immunity (100 KLux), and is designed for ultra-compact integration in IoT, robotics, drones, and industrial applications.

Super small and light (barely 1.3g), fits anywhere. Gets me 17–19 m on white walls inside, still pulls 11–13 m outside in daylight on decent targets. 100 Hz and even 250 Hz feel smooth if you filter a bit. Power draw is tiny too.
