X-NUCLEO-6180A1 Data brief Proximity Time-of-Flight sensor expansion board based on VL6180 for STM32 Nucleo Features VL6180 Time-of-Flight (ToF) proximity sensor Ranging measurement up to 62 cm 4-digit display, displaying the distance of a target from the proximity sensor Excellent ranging accuracy, independent of the reflectance of the target In order to easily integrate multiple VL6180 devices into customer devices, up to 3 external breakout VL6180 boards can be connected to the expansion board Breakout boards can be ordered using the reference VL6180-SATEL Compatible with STM32 Nucleo board family TM Equipped with Arduino UNO R3 connector RoHS compliant. Full system software supplied, downloadable from www.st.com/vl6180 in the folder Tools & Software Description The X-NUCLEO-6180A1 expansion board features the VL6180 proximity sensor, based on STs FlightSense, Time-of- Flight technology. It is an evaluation board that provides an introduction to the proximity ranging capabilities of the VL6180 module. The VL6180 is based on patented FlightSense technology. This is a ground-breaking technology allowing absolute distance to be measured independent of target reflectance. Instead of estimating the distance by measuring the amount of light reflected back from the object (which is significantly influenced by color and surface), Product summary the VL6180 precisely measures the time the light takes to travel to the nearest object VL6180 expansion and reflect back to the sensor (Time-of-Flight). X- board for STM32 NUCLEO-6180A1 It is compatible with the STM32 Nucleo board family, and with the Arduino UNO R3 Nucleo board family connector layout. Several ST expansion boards can be superposed through the Arduino connectors, which allows for the development of VL6180 applications with Bluetooth or WiFi interface (for example).
