Adafruit RGB Matrix HAT + RTC for Raspberry Pi - Mini Kit;

You can now create a dazzling display with your Raspberry Pi Model A+/B+/Pi 2 or Pi 3 with the Adafruit RGB Matrix HAT. This HAT plugs into your Pi and makes it super easy to control RGB matrices such as those we stock in the shop and create a colorful scrolling display or mini LED wall with ease. Each order comes with a HAT PCB with all surface mount parts assembled, a 2x20 female socket connector, a 2 pin terminal block, and a 2x8 IDC socket connector. A CR1220 coin cell is not included (required for real time clock). A 5V power supply is also required, not included, for powering the matrix itself. The Pi cannot do it due to the high currents. To calculate the max current of your matrix set up, multiply the width of all the chained matrix by 0.12 : A 32 pixel wide matrix needs 32*0.12 = 3.85A so pick up a 5V 4A power supply.
