../_images/crickit-cpb.jpg

The Adafruit Cricket is a baseboard which accepts an Circuit Playground Bluefruit (CPB) on top and adds motor drivers, servo output connectors, motor power input, and more. It operates independently from the CPB, communicating via an I2C bus connected via screws.

Features

  • 4 x Analog or Digital Servo control, with precision 16-bit timers

  • 2 x Bi-directional brushed DC motor control, 1 Amp current limited each, with 8-bit PWM speed control (or one stepper)

  • 4 x High current “Darlington” 500mA drive outputs with kick-back diode protection. For solenoids, relays, large LEDs, or one uni-polar stepper

  • 4 x Capacitive touch sensors with alligator-pads

  • 8 x Signal pins, digital in/out or analog inputs

  • 1 x NeoPixel driver with 5V level shifter

  • 1 x Class D, 4-8 ohm speaker, 3W-max audio amplifier

The Crickit can drive up to six small DC motors or pumps using the four Darlington and two motor drive outputs.
