Colorduino RGB LED Dot Matrix Driver Board

An Arduino-compatible driver board for an 8x8 RGB LED dot matrix, pairing a DM163 constant-current driver with an M54564 source driver to give hardware PWM color control. Multiple boards cascade over a single I2C bus to build larger RGB matrices.

Specifications

• DM163 constant current LED driver
• M54564 source driver
• 24 constant-current channels @ 100mA
• 8 source channels @ 500mA
• input voltage 5-7.5V
• I2C cascading
• UART/GPIO/ADC
• dimensions 60 x 60 x 11 mm

Compatible with

• 8x8 RGB common-anode LED matrix
• Arduino IDE (ATmega328-based)
• cascadable via I2C and power interface

Build it with Compoden's AI

Tell Compoden's AI build assistant what you want to display and it picks a compatible screen, checks it against your board's interface and voltage, and hands you the wiring and the driver code matched to the exact module - all from real in-stock parts.
