A simple clock for a 64x32 HUB75 LED matrix display powered by Adafruit's MatrixPortal M4 with NTP sync and a Sensirion SHT40 ambient sensor.
This repo is a consolidated example.
I'm still using the original MatrixPortal (25,90€):
The display (23,95€) is from WaveShare (and was much cheaper than the similar product from Adafruit):

Here I've found very valuable information about how to use this kind of display:

The sensor (7.95€) came on a convenient break-out board from Adafruit:
