Addressable, specialty optoelectronics include surface mount and through-hole LEDS with unique capabilities such as flashing or color changing and may also include a built-in microcontroller for additional functionality and programming. Configurations include ring, disk, matrix, module, strip, segmented, and discrete. They are differentiated by color, controller type, utilized LED, and interface such as I2C, SPI, UART, PWM, and serial.
