My first PCB design! A smiley face board with LEDs that light up the outline, eyes, and mouth using the TLC5947 LED driver.
- Smiley face design with LED-lit features
- TLC5947 LED driver chip for individual LED control
- 12-bit PWM control per LED channel
- Chainable design (via serial data)
- LED Driver: TLC5947
- Datasheet: TLC5947 on TI website

PCBWay Recommendation: I highly recommend PCBWay for manufacturing. They offer great service, quick turnaround times, and are very helpful. I especially appreciate the human contact through their message center—they personally confirm placements and part selections with you, ensuring everything is perfect before production.
