siliconray：ColorPAL Color Sensor Module

Brief introduction:
The ColorPAL is a light sensor and miniature color which doubles as a color generator through its RGB LED. For sensing color, the ColorPAL uses its LED to illuminate a sample, one color component at a time, along with a broad-spectrum light-to-voltage converter to measure the light reflected back. The amount of light reflected from the sample under illumination from each red, green and blue LED can be used to determine the sample’s color.

Features:
* Generates 24-bit color using onboard RGB LED.
* Detects a full range of colors, and outputs data as RGB (Red/Green/Blue) components.
* Detects broad-spectrum ambient light with sensitivity down to 44μW/cm2 per lsb.
* Onboard EEPROM for saving custom color detection and generation programs.
* Plugs into servo headers (with optional cable) or wireless breadboards.
* Color detection and generation details handled by onboard microcontroller.
* Autorun feature permits running a pre-designated EEPROM program with only a power supply.
* Single-pin interface uses a simple serial protocol to define and initiate color detection and generation.
Key Specifications:
* Power requirements: 5.0 VDC
* Communication: Serial 1-Wire (asynchronous serial, open drain)
* Dimensions: 1.72 x 0.90 x 0.65 in (44 x 23 x 17 mm)
