The base has a built-in 600mAh rechargeable lithium-ion battery and comes equipped with a power management IC for easy use as a portable, handheld device. There are 5 RGB LEDs each on the left and right sides of the base, PORTB and PORTC interfaces on the top, and POGO PIN contacts on the bottom of the backside of the base through which it can be charged from the charging base.
