16 CHANNEL 12 BIT PWM SERVO DRIVE SHIELD

    1.6kHz Maximum PWM frequency
    16 channels
    12-bit resolution (set 4096 levels of timing; 4?s 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")
    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
