hi there, thank you very much! I'll better make sure I buy up to date products in the future... Kind Regards, Hermann
Voltage Levels – Some LoRa modules and displays are 3.3 V logic, while ESP32 boards are also 3.3 V but some require proper level shifting for certain pins. Even a “level converter” may need to be bi-directional or properly wired.
