MAX7219 Dot Matrix Module 8 Dot Matrix Electronic Display Module 8 in 1 Display Module SCM Control Drive LED Module for Arduino Microcontroller

It works remarkably well for how little it cost. The order was two of these displays for what would normally be charged for just one anywhere else. My only issue is a minor issue, and that's the fact the pins are loose in the bag and not soldered on the board. I did the soldering myself in five minutes, and was then able to work with the display. I have mine connected to an Espressif ESP32-S3 DevKitC1 N8R8 purchased from Amazon running Micropython 1.22.1, with a MAX7219 library I found on GitHub.

This display was easy to set up and get working, I utilized an ESP32-S3 microcontroller with CircuitPython installed, and used the adafruit_max7219 library - everything works as expected. Would recommend for anybody looking for this type of display.

This is a nice package which includes straight and 90 degree headers for connecting it. The wires were also included, female to female. As you can see from the video, I hooked it up to an esp32 and ran a sample Arduino sketch. With most of the samples, keep in mind that you'll need to use the default pins for the SPI bus unless you like hacking header files. Overall great value for the money and I'm designing a case right now to house it all. As you you will also notice, I was driving it from the 5 volt pin on the ESP32 without any dropout. I haven't measured the total load or if lighting every pixel will brown out, but that's a mystery for another day.Enjoy!
