SWITCH SCIENCE Conta Digital Color Sensor Module

This sensor module uses ROHM's BH1745NUC digital color sensor to detect the color components (RGB) of light and obtain the illuminance and color intensity of ambient light. It uses an I2C interface and operates at a voltage of 2.3V to 3.6V. The sensor also supports 1.8V I2C buses; if you would like to change this setting, please refer to the BH1745NUC datasheet. This product can be used standalone or mounted on a Conta base shield. Pin headers are pre-soldered. *The Conta standard is a standard that ensures interoperability between breakout boards by establishing certain rules for their external dimensions, connectors, signal layout, etc.
*About ^I2C bus pull-up resistors: *This module does not have a built-in I2C bus pull-up resistor. If necessary, add a 1608 chip resistor to R2 and R3 on the surface of the board as appropriate. *How to set the ^I2C slave address: *The I2C slave address of this module can be selected by shorting solder jumper SJ1 on the surface of the board to either H or L. *Connecting the center pad to the "L" side will set the address to "38h", and connecting it to the "H" side will set the address to "39h" (this is the default setting at the time of shipment). Also, be sure to connect the center pad to either H or L.
