(1)Drive board connected to Arduino:

The PWM driver board uses the I2C method, 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

Old Mega pin way:

+ 5v -> VCC

GND -> GND

Digital 20 -> SDA

Digital 21 -> 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) power supply 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 you are directly using the Arduino 5V pin to power the servo directly, there are some unpredictable problems, so we recommend that you have a suitable external power supply 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 0 × 40, you can modify the upper right corner of the jumper I2C address. Connect a jumper with solder to indicate a binary number "1".
