Pinout
8| Pin | Name | Functions | Notes |
|---|---|---|---|
| BLANK | Blank | GPIO | Controls constant-current outputs off/on. |
| GND | Ground | GND | Power ground for the device. |
| IREF | Reference Voltage | GPIOADC | Sets constant-current value and can be used as an analog input. |
| OUT0-OUT23 | Constant Current Outputs | PWM | Provides 30mA of constant current for LEDs, with 4096 steps of PWM control. |
| SCLK | Serial Clock | SPI | Clocks data into the shift register. |
| SIN | Serial Input | SPI | Shifts in grayscale data for PWM control. |
| SOUT | Serial Output | GPIO | Outputs MSB of the grayscale shift register to reduce shifting errors. |
| VCC | Power Supply | POWER | Supply voltage for the device, range 3.0V to 5.5V. |
