CRICKIT for Circuit Playground Express

Adafruit CRICKIT for Circuit Playground Express is a creative robotics and interactive construction kit and add-on to the Circuit Playground Express. Bolt on the Circuit Playground using included stand-off bolts and control motors, servos, and solenoids. Signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output are also included. Extend the Circuit Playground and use all the goodies on the CPX, but with a robotics playground as well. The Crickit is powered by seesaw, I²C-to-whatever bridge firmware. Only two data pins are needed to control the huge number of inputs and outputs on the Crickit. All those timers, PWMs, sensors are offloaded to the co-processor.
