16 Channel Led Driver Arduino Apr 2026

You can daisy-chain up to 62 boards together to control a massive 992 LEDs using the same two pins.

While marketed for LEDs, it is equally popular as a servo driver.

Very affordable, with modules typically ranging from $3 to $16 depending on the brand. You can find them at retailers like AliExpress or Sears. Best for Precision: TLC5940 SPI Driver 16 Channel Led Driver Arduino

Reviewing a "16-Channel LED Driver" for Arduino typically involves choosing between two dominant chipsets: the (I2C interface) and the TLC5940 (SPI-like interface) . Both are excellent for expanding your PWM outputs when your Arduino’s built-in pins aren't enough. Best Overall: PCA9685 I2C Driver

Offers 12-bit resolution (4,096 brightness steps), providing much smoother fading than the Arduino's native 8-bit pins. You can daisy-chain up to 62 boards together

This is the most modern and "resource-friendly" choice for most Arduino users. It communicates over just two pins (SDA/SCL) and has its own internal clock, meaning it handles the PWM signals without taxing your Arduino's processor.

The TLC5940 is a "classic" constant-current driver. Unlike the PCA9685, it is a , meaning you don't need resistors for each LED—the chip handles it for you. Go to product viewer dialog for this item. You can find them at retailers like AliExpress or Sears
