OB-SX Power Mod

Provide power from your OB-SX to supply your magicBox

The magicBox requires DC 5V 130mA, indicating very low power consumption. There is no reason not to supply power to the magicBox from the OB-SX. It involves a simple modification, but it's important to note that this should be done by qualified technicians only.
Follow the steps below for this upgrade.
The magicBox does not require any modification as it is already prepared to work with the OB-SX power mod.

Die magicBox benötigt DC 5V 130mA, was auf einen sehr geringen Stromverbrauch hinweist. Es gibt keinen Grund, die magicBox nicht vom OB-SX mit Strom zu versorgen. Es handelt sich um eine einfache Modifikation, jedoch ist es wichtig zu beachten, dass diese nur von qualifizierten Technikern durchgeführt werden sollte. Folgen Sie den untenstehenden Schritten für dieses Upgrade. Die magicBox benötigt keine Modifikation, da sie bereits für die Verwendung mit der OB-SX Stromversorgung vorbereitet ist.

H28 is connected to H23-H27 (all to ground), so there is no trace to cut.

    1. Desolder the H28 female contact from the socket.
    2. Carefully bend Pin 28 out from the plug without breaking it.
    3. Solder a 1-ohm resistor between Pin 28 and the +5V trace.

That's it.
