Adafruit 12-Channel 16-bit PWM LED Driver - SPI Interface

Explore the power of precision with this breakout board for the TLC59711 PWM driver chip, offering control over 12 separate channels of 16-bit PWM output. This board stands out for achieving the highest resolution we've seen, specifically crafted for precision LED management.

Specifications highlight the board's constant-current, open-drain outputs, capable of handling multiple LEDs in series with an anode supply up to 17V. A smart on-chip 3.3V regulator is available for logic level requirements, and a unique design makes daisy-chaining simple, extending your control to limitless possibilities.

You need only two SPI pins for operation, adaptable to any digital microcontroller pins, supported by a comprehensive Arduino library to guide initial setups. An included current-set resistor, green power-good LED, and mounting holes enhance accessibility and ensure seamless integration into projects.

Employing a 3.3K resistor typically delivers about 15mA, but adjustments are possible by soldering a custom resistor to modify output. Keep in mind the insightful details for LED brightness consistency, regardless of power dips, outlined in the TLC59711 datasheet.
