Adafruit RGB Matrix HAT + RTC for Raspberry Pi - Mini Kit
The Adafruit RGB Matrix HAT + RTC for Raspberry Pi – Mini Kit is a powerful add-on board designed to make driving HUB75 RGB LED matrix displays from a Raspberry Pi simple and reliable. This HAT plugs directly onto compatible Raspberry Pi boards and provides an easy interface for creating scrolling text displays, digital clocks, animations, scoreboards, and colorful LED video walls. It features onboard level shifting circuitry for stable 5V matrix control, integrated power protection, and a built-in DS1307 real-time clock (RTC) for accurate timekeeping even when the Raspberry Pi is powered off.
Compatible with Raspberry Pi Zero, A+, B+, Pi 2, Pi 3, Pi 4, and newer supported models, the HAT works with HUB75 RGB LED matrices in sizes such as 16×32, 32×32, 32×64, and 64×64. It supports chaining multiple panels together to create larger displays for advanced projects. The onboard RTC allows time-based applications like clocks, scheduling displays, and information boards to maintain accurate time without internet connectivity.
