Adafruit RGB Matrix HAT Raspberry Review

The HUB75 connector is very poorly made. Two pins were inserted so that they protruded an inch from the back of the connector, meaning that any cable that plugged into that connector could not connect to those pins.

Using this Pi Hat is much easier than connecting it manually. There are several other boards, but this one is the easiest in my opinion. If you use this hat, make sure your panel is a HUB75 panel and not one of the other panel types floating around.

Ideal for prototyping projects. It's much easier to quickly wire up [compatible] panels that follow a direct GPIO connection. Completed all Pi demo projects as expected. Although my C programming sucks and I've had limited success compiling and running my own programs.

Pi3 power should work through this hat, but I'm only getting about 4.8V consistently to power the Pi and hence there is a flash to indicate low voltage. Turning on the old Pi3b caused the burnout - just booting up the Pi, no LEDs - even though they were connected. The result was magic smoke, and now it's DOA.

The hat makes it easier to interact with your Pi. Many people use their Pi to control lights for the holidays. This hat is plug and play. The only problem is that it comes with an unsoldered connector. You need to solder the GPIO to the board. Very easy. Great hat! No over or under current. Lots of security features to protect your Pi.

Adafruit kicks the ball out of the park with this RGB Matrix hat. I am creating a 16 x 164 RGB matrix to display local bus times and schedules for my wife. Easy to assemble and connect to Raspberry PI. You can see the build hat in the photos I've included. Screws and gaskets are not included. I added those. As a plus, they included a real-time clock. Great work Adafrut!

It works with panels I bought from Revain, but not identical Adafruit panels, and my queries to Adafruit support went unanswered. The Adafruit panels have a huge amount of static while all other panels I've tried have a sharp image. While the Matrix Hat works with some panels, the design is poor and soldering is a pain. Parts are often missing from packages and stands are needed as it had a Hub75 connector in the middle but doesn't include it. The Hub75 connector to be soldered is made of cheap

Works great for me! I bought a 128x64 LED dot matrix display here. I used my raspberry pi and drove it directly. It worked fine. But the Raspberry Pi IO is at 3.3V and the matrix display is usually at 5V, there are glitches on the display, especially when the brightness is reduced. With this cap, it converts 3.3V logic to 5V, and no more glitches! Please note that you have to solder the pins. The pads are placed close together to match the pins on the Raspberry Pi. It's good to turn the Pi over
