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