WW
I/O
Common I/O interface, which can be used for
PWM output of the LED driver. It controls the
warm white LED by default.

I/O
Used as the common I/O interface

SWS
I/O
Bluetooth chip programming pin
12
SCL
I/O
Pin for the clock line of the I2C interface, which
must be connected to a 4.7 kΩ pull-up resistor.
This pin can also be used as the common I/O
interface.
13
R
I/O
Common I/O interface, which can be used for
PWM output of the LED driver. It controls the red
LED by default.
14
CW
I/O
Common I/O interface, which can be used for
PWM output of the LED driver. It controls the cold
white LED by default.
15
RX
I/O
Serial port TX pin, used as the common I/O
interface
16
TX
I/O
Serial port TX pin, used as the common I/O
interface
Note: P indicates power-supply pins, and I/O indicates input/output pins.
The SWS pin is used only for programming of module firmware.
The I2C pin does not provide a pull-up resistor. It must be connected to an external pull-up
resistor.
When the WW pin is used for PWM output, its polarity is opposite to that of the R, G, B,
and CW pins used for PWM output.
If you have special requirements for the light color controlled by PWM output, contact our
business manager.
