Software considerations: I found 3 different libraries to use with the TM1637 – TM1637.h – recommended by RobotDyn but older – TM1637display.h library – by AVISHORPE seems to be the favorite – SevenSegmentTM1637.h – By breeme. Most functionality and possibilities. AD415_schematic TM1637_V2.4_EN Pro NODEMCU mi funguje tahle: https://github.com/bremme/arduino-tm1637
