Designed specifically for precision LED control, this board delivers smooth, flicker-free dimming across all channels.\n\nOnly two SPI pins are required for communication, and the design is fully chainable — connect as many boards as you need in series for expanded channel count. Each of the 12 outputs is constant-current and open-drain, with a V+ anode supply of up to 17V for driving multiple LEDs in series.\n\nKey Features\n\n\n12 PWM Channels – 16-bit resolution (65,536 steps) per channel\n\nConstant-Current Output – LED brightness stays consistent even if power supply dips\n\nChainable Design – Connect multiple boards in series for more channels\n\nSPI Interface – Only 2 pins required (works with any digital GPIO)\n\nOpen-Drain Outputs – Drive LEDs in series with up to 17V anode supply\n\nOnboard 3.3V Regulator – Available for logic-level regulation\n\nCurrent-Set Resistor – 3.3kΩ default (~15mA); replaceable with through-hole resistor for custom values\n\nPower-Good LED – Green indicator for supply status\n\n\nIdeal For\n\nPrecision LED dimming and colour mixing\nLED art installations and lighting rigs\nArchitectural and decorative lighting control\nMulti-channel indicator systems\n\n\nPackage Contents\n\n1× Adafruit TLC59711 12-channel PWM LED driver breakout\n1× 0.1\" header strip\n\n\n\nNote: This board is designed for LED control and is not suitable for driving servos. There is a silkscreen typo — the second R0 should read R1. Soldering required for header attachment. If driving digital inputs, use a pull-up resistor from the output pin to your logic level.\n\n\nSpecifications\n\n\nDriver Chip – TLC59711\n\nChannels – 12\n\nPWM Resolution – 16-bit (65,536 steps)\n\nV+ Supply – 5–17V DC\n\nDefault Current – ~15mA per channel (3.3kΩ resistor)\n\nInterface – SPI (DIN + CLK)\n\nLogic Level – 3–5V\n\n\nResources\n\nTLC59711 Datasheet (TI)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":7864,"title":"Default Title","sku":"AF-1455","price":14.8,"on_sale":false,"in_stock":true,"available_quantity":21,"option1":"Default Title"}]}
