16-Channel 12-bit PWM/Servo Shield - I2C interface

USD $17.50

It's an independent 16-channel, 12-bit PWM chip breakout that's ideal for driving LEDs or servos over an I2C network. Pretty handy for "Set-it & forget-it" installations.

DESCRIPTION

Pulse-Width Modulation (PWM) is the method microcontrollers use to set LED brightness and the position of servos, so it is a pretty well-understood technique. This 16-Channel 12-bit Interface lets you set these PWM signals to 16 devices through the convenient 2-wire I2C interface. Set your pin assignments over an I2C call, and forget it - the chip will keep generating the signals until told otherwise!

This breakout board is configured to allow up to 62 live in a single chain, letting you run up to 992 PWM outputs. That's a lot of servos/LEDs under your control!

Specifications

  • 1.6kHz Maximum PWM frequency
  • 16 channels
  • 12-bit resolution (set 4096 levels of timing; 4µs resolution at 60Hz update rate)
  • 3.3V - 5V compliant (allows a 3.3V device drive up to 6V outputs on the chip)
  • 62-device chain capable
  • Configurable open-drain / push-pull driver output
  • Dimensions (no headers or terminal block) 54mm x 70mm x 3mm (2.1" x 2.7" x 0.1")

Features

  • Power input terminal blocks with reverse-polarity protection, or 0.1" headers
  • Green and red "power-good" indicator LEDs
  • 4 groups of 3-pin connectors for easy 16-servo attachment (servo plugs will "crowd" 0.1" headers)
  • Stackable design using 90 degree 3x4 headers
  • Position for large power filter capacitor
  • Output lines have 220 ohm protection resistors (also allows direct LED attachment to the board)
  • Solder jumpers for the 6 address select pins
