Radxa Zero > Development > Using ADB
Contents
Description
Radxa Zero supports Android Debug Bridge (adb), so you can open a shell or send file directly to Radxa Zero when network connection is not available.
One USB Type-C charging data cable can provide power while access the device in adb mode.
Here we use a Type-C to Type-A USB cable with Type-C end plugged in the power port of Radxa Zero, while the other end plugged into our computer.
