Circuit Playground Express + Crickit

by Adafruit

Image of Board

Crickit is a Creative Robotics & Interactive Construction Kit. It’s an add-on for the popular Circuit Playground Express that lets you #MakeRobotFriend using CircuitPython (and more).

Bolt on a Circuit Playground using the included stand-off bolts and start controlling motors, servos, solenoids. With CRICKIT you also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends the Circuit Playground so you can still use all the goodies on the CPX, but now you have a robotics playground as well.

The Crickit is powered by seesaw, a I2C-to-whatever bridge firmware. So you only need to use two data pins to control the huge number of inputs and outputs on the Crickit. All those timers, PWMs, sensors are offloaded to the co-processor.

Includes:

  • 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

All are powered via 5V DC, so you can use any 5V-powered servos, DC motors, steppers, solenoids, relays etc. To keep things simple and safe, CRIKIT does not support mixing voltages, use only 5V - not for use with 9V or 12V robotic components.

CircuitPython 4.0.1

This is the latest stable release of CircuitPython that will work with the Circuit Playground Express + Crickit.

Start here if you are new to CircuitPython.

Release Notes for 4.0.1

CircuitPython 4.0.0-rc.3

This is the latest unstable release of CircuitPython that will work with the Circuit Playground Express + Crickit.

Unstable builds have the latest features but are more likely to have critical bugs.

Release Notes for 4.0.0-rc.3

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for it. They are stored on Amazon S3 by language (some which may be unreleased.) Try them if you want the absolute latest and are feeling risky.

Past Releases

All previous releases are available on GitHub. They are handy for testing but we recommend the latest stable otherwise.
