A light-to-frequency converter is connected to an 8 x 8 array of photodiodes. Sixteen photodiodes have blue filters, 16,photodiodes have green filters, 16 photodiodes have red filters, and 16 photodiodes are clear with no filters. The colour group used for conversion is pin-selectable.
Communicates directly with a microcontroller Pin-selectable colour Pin-selectable output scaling Power down Stable temperature coefficient of 200 ppm/°C
