Product Introduction:
Want to make a hexapod walker? Maybe you're making a piece of art with tons of moving parts, or you need to drive at on of LEDs with precise PWM output. Your microcontroller has a Limited number of PWM outputs, and you find yourself running out! Not with the Ada fruit 16-Channel 12-bit PWM/Servo Driver-I2C interface. With this pwm and servo driver breakout, you can control 16 free-running PWM outputs with just two pins! Need to run more than 16 PWM outputs? No problem. Chain together up to 62 of these beauties for up to an outstanding 992 PWM outputs.

Features:
Dimensions(no headers or terminal block) 2.5"x 1"x 0.1"(62.5mmx 25.4mmx3mm) .
Weight(no headers or terminal block) :5.5grams
Weight(with 3x 4 headers & terminal block) :9grams

This board/chipusesI2C 7-bit address between 0x 60-0x 80,selectable with jumpers Terminal block for power input(or you can use the 0.1"breakouts on the side) Reverse polarity protection on the terminal block input.Green power-good LED.

3 pin connectors ingroups of 4 so you can plugin 16 servos at once(Servo plugs are slightly wider than 0.1"so you can only stack 4 next to eachother on 0.1"header"Chain-able"design

A spot to place a big capacitor on the V+line(in caseyou need it) .

220ohm series resistors on all the output Lines to protect them, and to make drivingLEDs trivial Solder jumpers for the 6 address select pins.

j2c-controlled PWM driver with a builtin clock.Unlike the TLC 5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running!

It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive upto6V outputs (this is good for when you want to control white or blue LEDs with 3.4+forward voltages) .

6 address select pins so you can wire up to 62 of these on a single i2cbus, a total of 992 outputs-that'sa lot of servos or LEDs.

Adjustable frequency PWM_up to about 1.6KHz 12-bit resolution for each output-for servos, that means about 4usresolutionat60Hz update rate, Configurable push-pull or open-drain output, Output enable pinto quickly disable all the outputs.

Instructions for use:
1.Drive board connected to Arduino:

The PWM driver board uses the l2Cmethod, so only four lines can be connected to the Arduino device: "Classic" Arduino pin mode:
+5v->VCC
GND->GND
Analog 4->SDA
Analog 5->SCL

R3 and later Arduino pin method(Uno, Mega & Leonardo) :(These boards have dedicated SDA and SCL pins)
+5v->VCC
GND->GND
SDA->SDA
SCL->SCL

VCC pin is only for the chip power supply, if you want to connect the servo or LED lights, use the V+pin power supply, V+pin supports 3.3~6V power supply(chip safe voltage 5V) .It is recommended to connect the external power supply via the power supply terminal.

2.powersupply part:
Most of the servo design voltage is 5~6V, especially in a number of steering gear at the same time running, with the need for high-power power supply.If youare directly using the Arduino5Vp into power the servo directly, there are some unpredictable problems, so we recommend that you have a suitable external powersupply for the drive board.

3.Connect the servo:
Most servos are connected using standard 3-wire female plugs, as long as the corresponding pin into the driver board on it.(Ground wire is generally black or brown, the signal line is generally yellow or white)

4.for the driver board assigned address:
Each drive board of the cascade needs to have a unique access address.The initial I2C address of each driver board is 0x 40, you can modify the upperright corner of the jumper I2C address.Connect a jumper with solder to indicate a binary number 1.
