Tablet Tastatur USB-Adapter

Beitragvon Sebastian » 30.05.2017, 22:33

Hallo liebes Forum,
nach langer Zeit melde ich mich hier mit einem Adapter zurück, der eine Tablet-Tastataur (Genauer eine vom SurfTab twin 11.6, ähnlich einer W10a) USB anschlussfähig macht. Da die Tastatur ein Touchpad und zwei USB-Buchsen integriert hat, habe ich mir gedacht, warum sollte der anschluss am Tablet nicht auch USB sein. Eine Messung mit dem Oszi ergab folgende Belegung:

Da die Pins Federkontakte sind und im 2,54mm Raster sind, hat sich eine durchkontaktierte Lochrasterplatine angeboten, an der ein USB-Kabel angelötet werden konnte. Die Tastatur wird mit Magnetkraft am Tablet festgehalten, und dies habe ich mir auch für meinen Adapter zunutze gemacht. Etwas Heißleim und Holz und fertig ist meine mobile Tastatur mit 2 USB-Anschlüssen und Touchpad fürs Handy.
