P-NUCLEO-6180X2

P-NUCLEO-6180X2 Proximity, gesture, ambient light sensor expansion board based on VL6180X for STM32L053R8 Data brief integrate the VL6180X in customer’s application. • Basic gesture recognition application can be developed using the VL6180X sensor on the expansion board and/or up to three sensors on the satellite boards. Description The P-NUCLEO-6180X2 is an evaluation pack that provides an introduction to the proximity, ranging and light sensing capabilities of the VL6180X sensor, combined with the ultra low power STM32L053R8 microcontroller. Features • 1x VL6180X (proximity, gesture and ambient light sensing module) expansion board. – Slider switch controlling 2 functions: - Ranging measurement. - Ambient light sensing, up to 100KLux.(a) – 4-digit display, displaying either the distance of a target from the proximity sensor or the lux value from the ambient light sensing (ALS). – Excellent ranging accuracy, independent of the reflectance of the target. • 1x NUCLEO-L053R8 board • Power management access point • Equipped with Arduino UNO R3 connector. • RoHS compliant. The VL6180X is the latest product based on ST’s patented FlightSenseTM 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), the VL6180X precisely measures the time the light takes to travel to the nearest object and reflect back to the sensor (Time-of-Flight). The STM32 Nucleo board, NUCLEO-L053R8, provides an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller line, choosing from the various combinations of performance, power consumption and features. • Full system SW supplied, download from www.st.com/vl6180x in the folder “Design resources”. • 3x VL6180X satellite boards can be connected on the VL6180X expansion board, in order to a. VL6180X detects up to 100KLux but since the display is 4 digits only, maximum displayed value is limited to 9999 Lux June 2015 DocID027625 Rev 3 For further information contact your local STMicroelectronics sales office. 1/8 www.st.com Ordering information P-NUCLEO-6180X2 Ordering information Table 1.

VL6180X expansion board The board allows the user to test the VL6180X functionality, to program it and to help understanding how to develop an application using VL6180X. It integrates: • a 4-Digit display to render either the range value in mm or the ambient light value in Lux. • a switch to select the value type to be displayed. • a 2.8V regulator to supply the VL6180X. • two level shifters to adapt the I/O level to the micro controller main board. • the necessary connectivity for the application. It is required to program the NUCLEO-L053R8 board in order to control the VL6180X expansion board. For the NUCLEO-L053R8 board, the required software suite is available on www.st.com, on the P-NUCLEO-6180X2 page, and is composed of STSW-LINK008, STSW-LINK7 and the X-CUBE-6180XA1. The VL6180X expansion board and the NUCLEO-L053R8 board are connected through Arduino compatible connectors CN5, CN6, CN8 and CN9 as shown in Figure 1 and described in Table 2 and Table 3.
