SWITCH SCIENCE PCA9624PW 8-channel I2C voltage switch type LED controller pitch conversion module

This 8-channel LED driver board features an ^I2C connection and is equipped with NXP's PCA9624PW, allowing you to control the brightness and dimming of LEDs using PWM. The board also includes LEDs, so simply connecting to the ^I2C bus and issuing commands will cause the eight LEDs to light up smoothly. The LEDs are arranged at equal intervals in a straight line. For detailed control instructions, please refer to the manufacturer's website or the PCA9624PW datasheet. Includes 8 independent LED ports, an output enable function for the LED ports, on/off control and 256-level (8-bit) PWM gradation control for each port, independent or group control for each port, and 8 red LEDs. Includes a signal pin for external drive, and the ^I2C address can be set to any value. Includes an ^I2C pull-up resistor pattern (resistors not implemented).
Please prepare your own pin headers and solder them according to your needs. Regarding the LED port's output enable function: The PCA9624PW has an output enable pin (OE), which is pulled up on the module by default. To light the LED, connect the OE pin to GND to enable the port output. Regarding the ^I2C pull-up resistor: By default, an ^I2C pull-up resistor is not implemented. If you want to add one, solder a 1608-size chip resistor to R10 and R11 on the back of the board. Regarding the ^I2C address: The default address is 0xC0 (1100 000X) via solder jumpers (A6 to A0). You can change the lower half of the ^I2C address by modifying the solder jumpers (A2, A1, A0) on the front of the board. To change the upper half of the address, you must modify the solder jumpers (A4, A3) on the front of the board and the solder jumpers (A6, A5) on the back of the board. *If you want to change it, you need to cut the jumper pattern and then connect it to VDD(1) or GND(0) with a wire.
