DuinoTech Arduino Compatible 8×16 LED Matrix Display – Blue, I2C, AIP1640

You need a display that shows text and simple graphics without wiring up sixteen data lines. This 8×16 matrix has 128 bright blue LEDs and talks to your microcontroller over I2C – just GND, VCC, SDA, SCL. The AIP1640 chip handles the multiplexing so your code stays clean. Brightness is adjustable. It runs on 3.3V or 5V, and the box includes a 220mm four-pin cable so you can mount it away from the controller board. 400mW draw. 450kHz oscillation frequency

• 128 bright blue LEDs in an 8×16 grid with brightness control
• I2C interface (GND, VCC, SDA, SCL) – four wires, no parallel bus
• AIP1640 driver chip handles multiplexing for you
• Runs from 3.3V or 5V; 220mm four-pin cable included in the box
• 400mW power consumption at 450kHz oscillation frequency
