16-channel PWM / Servo Controller This board allows you to control 16 PWM or Servo channels using a simple I2C interface. Pulse frequency can be set anywhere between 16Hz and 1500Hz (max 400Hz for servos), making it ideal for motor speed control, LED brightness control and also for generating accurate Servo pulses.
Operating power supply voltage range of 3.3V to 5.5V. 1MHz Fast-mode Plus compatible I2C-bus interface

Arduino UNO*Pro Arduino UNO*Pro
The UNO is still a great development board, but it loses out to its big brother the Arduino Mega2560 in many areas. The Mega has 4x the flash program space, 8x as much RAM, 4 serial ports and many more IO pins, but comes in a larger format and a number of shields are not compatible.

This is where the UNO*Pro upgrade board comes in. The UNO*Pro is a simple plugin replacement for the existing ATmega328 chip (DIL socket version) and turns your existing UNO (or Duemilanove or Diecimila) into something much closer to a Mega board whilst retaining the UNO form factor and shield compatibility. The UNO*Pro has 128K of program space, 16K RAM, 2 serial ports and much more.
