Spi Pwm Led Driver

The TLC59711 and TLC5947 breakout boards are ideal for applications requiring precise control of lots of LEDs.

The TLC59711 can control 12 separate channels of 16-bit PWM output. This is the highest-resolution PWM board we ve seen.

The TLC5947 has even more channels. It can control 24 separate channels with 12-bit PWM output.

Both boards have a 2 or 3-pin SPI interface. Our library lets you use any two TLC59711 or three TLC5947 free pins to drive them. Best of all, you can chain multiple boards together to control hundreds or thousands of LEDs.

Outputs from these boards are constant-current and open drain. You can drive multiple LEDs in series. One resistor is used to set the current for each of the outputs, the constant current means that the LED brightness doesn t vary if the power supply dips.

We supply these with a 3.3K resistor for about 15mA per channel. But you can solder a thru-hole resistor over it if you d like to change that value

For all of you out there who want to control 24 channels of PWM, we salute you. We also would like you to check out this breakout board for the TLC5947 PWM driver chip. This chip can control 24 separate channels of 12-bit PWM output. Designed and ideal for LED control, this board is not good for driving servos. If you need to drive servos, we have a controller for that over here.

Only three SPI pins are required to send data our Arduino library shows how to to use any digital microcontroller pins. Best of all, the design is completely chainable. As long as there s enough power for all the boards you can chain as many as you d like, like a little trail of blue PCBs stretching out into the sunset. Each of the 24 output s is constant-current and open drain. You can drive multiple LEDs in series, with a V anode supply of up to 30V. If you want to drive something that requires a digital input, you must use a pullup resistor from the drive pin to your logic level to create the full waveform.

One resistor is used to set the current for each of the outputs, the constant current means that the LED brightness doesn t vary if the power supply dips. We use a 3.3K resistor for about 15mA but you can solder a thru-hole resistor over it if you d like to change that value. Check the TLC5947 datasheet for details on resistor-to-current values.

We include a few extras to make this board easy to use: a durable 5V low-dropout regulator with reverse polarity protection in case y know, you plug it in backwards, a green power-good LED, four mounting holes and a current-set resistor. A bit of 0.1 header is also included so you can solder it on and plug into a breadboard.

To use: Power V with 5-30VDC, and connect ground to the common ground. Then send 3-5V logic SPI data on DIN data in, CLK clock and LAT latch. If you d like to quickly turn off all the outputs, raise the OE pin - it s pulled low to enable the PWM outputs.Our Arduino library will get you started with blinking LEDs, install it and run the example code with the noted pin configuration.
