Pinout
8| Pin | Name | Functions | Notes |
|---|---|---|---|
| VIN | Power | POWER | Connect to the same power as your microcontroller's logic level. |
| GND | Ground | GND | Common ground for power and logic. |
| SCL | I2C Clock | I2C | Connect to your microcontroller's I2C clock line. |
| SDA | I2C Data | I2C | Connect to your microcontroller's I2C data line. |
| INT | Interrupt Output | GPIO | Can alert you when input value changes. |
| RST | Reset | GPIO | Hardware reset pin with 10kΩ pull-up resistor. Set low to perform a hardware reset. |
| A0, A1 | I2C Address Select Jumpers | GPIO | Used to change the default I2C address from 0x58 (A0 shorted), 0x59 (A1 shorted) or 0x5B (both shorted). |
| 0-15 | GPIO Pins | GPIOPWM | Can be used as input or output. Supports 8-bit linear constant-current LED dimming. |
