The Nootropic RGB Matrix Backpack is a small Arduino-compatible controller board that snaps directly onto the back of a 16×32 RGB LED Matrix Panel. It handles all the complex wiring internally, so you can focus on programming colour animations and displays using the Arduino IDE.

The board is built around an ATmega328 (pre-loaded with a demo animation) and includes a 2.1 mm power jack, terminal block for panel power, a 6-pin FTDI programming header, and a tactile button connected to pin 10 for user input.

Key Features

• Snap-On Design – 8×2 female header connects directly to the matrix panel
• Arduino-Compatible – Program via Arduino IDE (select "Arduino Uno" as board type)
• 2.1 mm Power Jack – Accepts a regulated 5V supply (2A recommended)
• Terminal Block – Passes power through to the RGB matrix panel
• 6-Pin FTDI Header – Program using an FTDI Friend or FTDI cable
• Tactile Button – Connected to Arduino pin 10 for user input
• Pre-Loaded Demo – ATmega328 ships with a colour animation sketch

Ideal For

• Colour animations and scrolling text displays
• Interactive signage and art installations
• Learning Arduino programming with visual output
