Technical Parameters:
Voltage: DC5-10V power supply
Communication Interface: IIC
16-way steering gear control
Size:25*61mm

Product features:
The PCA9685 chip is wrapped in the center of the board
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

Cascade 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
