Sparkfun原廠 TLC5940 Breakout (BOB-10616)
SparkFun LED Driver Breakout - TLC5940 (16 Channel)
影片：https://youtu.be/caIay1MoPyY
Description:
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. 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.／TLC5940 是一個 16 通道 PWM 單元，具有 12 位元佔空比控制（0-4095）、6 位元電流限制控制（0-63）。
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.／使用此板可以增加微控制器可用的 PWM 引腳數量，以用於單色、多色或全彩 LED 顯示器、LED 標誌、顯示背光、伺服控制等應用或任何其他需要大量 PWM 驅動器的項目。
【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.
＊雖然每個 3針 PWM 接口的間距為 0.1 英寸，但為了方便連接伺服電機，每個接口之間的間距略大。
＊為了使該板適合與伺服馬達配合使用，每個輸出端都配備了 2.2kΩ 上拉電阻。
＊最後，Iref 引腳上的 2.2kΩ 電阻將輸出電流設定為17.8mA，但並聯的通孔連接提供了一個額外的電阻，以便在必要時增加電流。
＊若要確定給定輸出所需的電阻值，請查閱原理圖上提供的公式。
