    Customer reviews for "HC-12, SI4438- 433MHz radio module - range up to 1000 meters"
    By: Am: 8 Dec 2025

    Spiralantenne an der falschen Stelle angelötet, ansonsten gut!

    Nachdem ich die Antennenspirale abgelötet und 17 cm Draht am Lötpunkt "Ant" angelötet habe funktionieren die Module sehr gut

    By: Am: 7 Feb 2025

    Angebrache Antenne leider falsch verlötet

    Die Antenne ist bei den mir gelieferten Modulen an Pin 9 (NC) angelötet.
    Die Beschreibung im Datenblatt lautet: No connection, used in fixing, compatible with HC-11 module pin position

    By: Am: 25 Jul 2024

    Bin sehr zufrieden

    Klein und einfach zu handhaben. Habe umgehend einen Print entworfen, um die Module einfach mit Arduino MKR, Raspberry GPIO und COM (mit Level Shifter) nutzen zu können. Die Reichweite reicht für meine Zwecke, auf rechtliche Betriebsbeschränkungen achten! Half-Duplex Einschränkung beachten!

    By: Am: 4 Dec 2023

    Reichweite gut

    Habe die Funkmodule getestet und funktionieren für meine Zwecke problemlos.
    Reichweite durch 2 Betondecken etwa 20m Luftlinie für mich völlig in Ordnung

    By: Am: 11 Apr 2022

    Reichweite zu gering

    Man braucht keine zusätzliche Bauteile. Lässt sich problemlos anschließen. Ich brauche 38400 Baud. Da ist die Reichweite bei ca. 50 m aus der Wohnung heraus am ende.
