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 [Hide]
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
