The TLC5940is a 16 channel PWM unit with 12 bit duty cycle control
(0-4095), 6 bit current limit control (0-63), and a daisy chainable
serial interface. This breakout board is a good way to take full
advantage of this useful IC. All 16 PWM channels are broken out to
standard 0.1" headers, which run alongside convenient voltage and
ground rails. Also, because the TLC5940 can be daisy-chained, the
breakout is designed to support that feature. On the left-hand side of
the board all serial inputs are broken out to 0.1" headers and
likewise with output on the right-hand side.

Use this board to increase the number of PWM pins available to your
microcontroller for applications such as Monocolor, Multicolor or
Full-Color LED Displays, LED Signboards, Display Backlighting, Servo
control, or any other project where a large number of PWM drivers are

Note: While each 3-pin PWM header is 0.1" spaced, the space between
each header is slightly larger in order to accommodate servo
connections. In order to make this board suitable for use with servos,
2.2k pull-up resistors have been included on each output as well.
Finally, the 2.2k resistor on the Iref pin sets the output current to
17.8mA but a parallel through-hole connection is provided for an
additional resistor to increase the current if necessary. To determine
the resistor value you need for a given output check the equations
provided on the schematic.
