Hey
Versuche ein ähnliches Projekt zu starten. Momentan habe ich einen Arduino Nano den DHT22 und das Sim800L Modul. Wissen sie ob mein Arduino Nano über die 3.3V Anschlüsse das GSM Modul versorgen kann ? Oder brauche ich eine eigene Stromversorgung (würde ein altes USB-Kabel nehmen mit einem DC DC Stepdown Wandler von 5V auf 3.7V)?
