Adafruit CRICKIT HAT for Raspberry Pi
Develop your own robot with CRICKET - Adafruit's Creative Robotics & Interactive Construction Kit. This is an expansion board for the popular Raspberry Pi platform and is compatible with Allen models with a 2x20-pin header.
Simply plug the Crickit circuit board onto your Raspberry Pi and control servos, motors and much more immediately. The Cricket has seesaw support and only uses two I2C data lines of the microcontroller to control all existing components (I / Os, timers, PWM outputs, sensors). Only the audio output is not provided via seesaw.
The Crickit offers the following product features:
All inputs and outputs are designed for voltages of 5 V. 9 or 12 V components are not supported. Please note that you need a 5V power supply to operate the cricket, which is not included in the scope of delivery.
