scan switches for 198 LED dots:
  * Supply range from 2.7 V to 5.5 V
  * 0.1mA - 50mA per current sink
  * 1MHz I2C and 12MHz SPI control interface
  * 8-bit analog dimming
  * 8/16-bit PWM dimming
  * individual ON and OFF control for each LED dot
  * globat 3-bit Maximum Current setting for all LED dots
  * individual LED dot open/short detection

I'm not really sure what you're attmpting here with the minItems: 1, maxItems: 12.
Are you sure you didn't mean maxItems: 1, minimum: 1, maximum: 12?
