16-Channel 12-bit PWM and Servo shield with I2C interface for Arduino UNO R3 (OT2101-C45)

Ideal for making a robot with lots of servos like a Hexpod Walker. Or maybe you want to drive lots of LEDs with precise PWM output. Then you find out that your Arduino doesn't have enough PWM outputs, or that they conflict with another shield! What now You could give up OR you could get this handy PWM and servo driver shield. This shield works with all Arduinos that support shields. The chip on this shield is perfect for it. By using only two I2C pins you can drive 16 independent PWM outputs. You can even stack 62 shields on top of each other to drive a total of 992 PWM outputs. Because I2C is a shared bus you can also connect other I2C devices and sensors to the SCL/SDA pins as long as their addresses don't conflict. I2C controlled PWM driver with a built in clock. This means that unlike the TLC5940 family you don't have to drive it all the time. It runs completely independently.Suitable for 5V, you can also drive it from a 3.3V ESP32, ESP8266 or Wemos.I2C address can be set using 6 pins.Adjustable PWM frequency up to about 1.6kHz.12-bit resolution for each output - for servos that means a 4µs resolution at a 60Hz update rate.Configurable push-pull or open-drain outputThis shield features:terminal blocks for power input or you can use the breakout on the side.Protection against wrong connections to the terminal blocks.3 pin connectors in groups of 4 so you can connect 16 servos in one.Stackable design.Room for a large capacitor on the V+ line (if you need one).220 Ohm resistors on all outputs to protect them and to make driving LEDs easy.The pins are pre-soldered as shown in the picture.DimensionsLength: 6.8cmWidth: 5.3cmHeight: 2cm
