Product description: NeoTrellis RGB Driver PCB - 4x4 keyboard with backlit buttons - Adafruit 3954
NeoTrellis RGB Driver PCB keyboard with 16 buttons arranged in a 4 column by 4 row layout. Each button is illuminated with a separate RGB LED, so the keys can glow in different colors to achieve an amazing visual effect. The PCB board measures 60 x 60 x 7.5 mm, so it is an optimal choice for compact designs. In addition, the keyboard can be combined into larger panels (up to 32 boards), which gives almost unlimited adaptability. The NeoTrellis RGB Driver PCB uses the I2C bus for communication and has a Grove and JST-PH compliant connector.
