2.8V Regulator - Provides the required 2.8V for the sensor
I2C Level Shifter - Provides logic level conversion from 2.8V to VCC
Ambient Light Sensor
Measures absolute range up to 10cm
Two Programmable GPIO
Sharp Sensor Board Layout
VIN This is the main 2.7 V to 5.5 V power supply connection. The SCL and SDA level shifters pull the I²C lines high to this level.
GND The ground (0 V) connection for your power supply. Your I²C control source must also share a common ground with this board.
SDA/SDI/SDO Level-shifted I²C data line: HIGH is VIN, LOW is 0 V
SCL/SPC Level-shifted I²C clock line: HIGH is VIN, LOW is 0 V
GPIO0/CE This pin is configured as a chip enable input on power-up of the VL6180X; the board pulls it up to VDD to enable the sensor by default. Driving this pin low puts the sensor into hardware standby. After the VL6180X powers up, this pin can be reconfigured as a programmable interrupt output (VDD logic level). This input/output is not level-shifted.
GPIO1 Programmable interrupt output (VDD logic level). The VL6180X also drives this pin low when it is in hardware standby. This output is not level-shifted.
