This is RFID/RFID Smart Ring with a 22mm Inner Diameter

That means you need two pins

Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface (PCA9685) _BF25_10 R- cold line for rightYou want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your microcontroller has a limited number of PWM outputs! What now? You could give up OR you could just get this handy PWM and Servo driver breakout. When we saw this chip, we quickly realized what an excellent add on this would be. Using only two pins,
