Adafruit 16-Channel 12-bit PWM/Servo Shield - I2C interface
Adafruit 1141 - Adafruit Assembled Data Logging shield for Arduino
Introducing Adafruit FONA 808 GSM + GPS Shield, an all-in-one cellular phone module with that lets you add location-tracking, voice, text, SMS and data to your project, in Arduino shield format for easy use. Adafruit 2636
This Kit with fully-dedicated PWM driver chip handles all the motor and speed controls over I2C. Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors; you can also connect any other I2C devices or shields to the same pins. This makes it drop-in compatible with any Arduino, such as the Uno,...
