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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
