The TLC5940 is 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.<br> This breakout board is a good way to take full advantage of this useful IC.<br> All 16 PWM channels are broken out to standard 0.1" headers, which run alongside convenient voltage and ground rails.<br> Also, because the TLC5940 can be daisy-chained, the breakout is designed to support that feature.<br> 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.<br> Specification:<br> 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 necessary.<br> Size: Approx. 60x 32x 3.5mm/ 2.36x 1.26x 0.14inch<br> Package Includes:<br> 1 Piece LED Driver Breakout<br> Note:<br> While each 3-pin PWM header is 0.1" spaced, the space between each header is slightly larger in order to accommodate servo connections.<br> In order to make this board suitable for use with servos, 2.2k pull-up resistors have been included on each output as well.<br> 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.<br> To determine the resistor value you need for a given output check the equations provided on the schematic.<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-DIMEANI official store
