Matrix Display mit MAX7219, ESP8266 und GY-21 in MicroPython keinebook An über 32 GPIO-Pins stehenA nice big display alone can't be everything. After all, you don't buy a car just to put it in the garage so that it doesn't feel so alone. That's why the blog for this set shows the use of the matrix display with GY 21 temperature and humidity sensor and ESP8266. Due to the small number of components, this project, as well as the matrix display itself, is well suited for beginners. With the large LED matrix, you can display the values of the HTU21
