Review on π‘ HiLetgo 3pcs MAX7219 8x8 Dot Matrix LED Display Module 5V MCU Control MAX7219 88 LED Dot Matrix DIY Kit - Ultimate LED Display Solution by Jack Harrell
They work. 4 stars because the description doesn't mention the color (RED)
After soldering and testing with the ESP8266 MCU node, they work. On the Internet you can find many instructions on how to connect. And the color of the LEDs is red, in case you're interested.
