Product description
An I2C-controlled PWM driver with a built in clock. That means that, unlike the TLC5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running!

Parameter:
Power input terminal
Green power indicator
In the 4 groups of 3-pin connector to facilitate the insertion of 16 servo motor (servo motor plug slightly wider than 0.1 ")
The polarity of the reverse polarity is input on the terminal block Voltage: DC5-10V power supply
Communication Interface: IIC
16-way steering gear control
1.Output enable pin to quickly disable all the outputs
2. Terminal block for power input (or you can use the 0.1" breakouts on the side)
3. Reverse polarity protection on the terminal block input
4. Green power-good LED
5. 3 pin connectors in groups of 4 so you can plug in 16 servos at once (Servo plugs are slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header
"Chain-able" design.
V + line to place a large capacitor, the maximum external input voltage depends on the 10V 1000uf capacitor
All PWM output lines have a 220 ohm series resistor protection and can easily drive LED
330 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial.
Solder jumpers for the 6 address select pins.
Package including:
5pcs x PWM Servo Motor Driver
