Tutorial: TLC5947 and TLC59711 PWM LED Driver Breakouts

Leds Drivers
Tutorial: TLC5947 and TLC59711 PWM LED Driver Breakouts @ The Adafruit Learning System! The TLC59711 and TLC5947 breakout boards are ideal for applications requiring precise control of lots of LEDs.

Leds 1455 Lrg
The TLC59711 can control 12 separate channels of 16-bit PWM output. This is the highest-resolution PWM board we’ve seen!

Leds 1429 Lrg
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.
