Color 15 Click Board™

Product Code: MIKROE-5121

How Does The Color 15 Click Board™ Work? The Color 15 Click Board™ as its foundation uses the CLS-16D24-44-DF8/TR8, a digital I2C compatible interface color light sensor from Everlight Electronics. It supports parallel output for Red, Green, Blue, White and Infrared light (R, G, B, W, IR) and converts them to a 16-bit digital value (0-65535). This sensor is characterized by high resolution designed to reject IR in light sources allowing the device to operate in environments from sunlight to dark rooms, with a maximum detection lux of 204.679lux. Besides, an integrated ADC rejects 50Hz and 60Hz flickers caused by artificial light sources. It also has stable performance over a wide temperature range of -40°C to 65°C, suitable for measuring the present color light. The CLS-16D24-44-DF8/TR8 does not require a specific Power-Up sequence but requires a voltage of 1.8V for its interface and logic part to work correctly. Therefore, a small regulating LDO is used, the MAX8511, providing a 1.8V out of both 5V and 3.3V mikroBUS™ power rails.

The Color 15 Click Board™ communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 400kHz, fully adjustable through software registers. Since the sensor for operation requires a power supply of 3.3V, this Click board™ also features the PCA9306 and SN74LVC1T45 voltage-level translators. The I2C interface bus lines are routed to the voltage-level translators allowing this Click board™ to work with both 3.3V and 5V MCUs properly. Also, it uses an interrupt pin, the INT pin of the mikroBUS™ socket, used when an interrupt occurs to alert the system when the color result crosses upper or lower threshold settings. The Color 15 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library that contains easy-to-use functions and an example code that can be used, as a reference, for further development.
