This unit is a self-contained assembly with enclosure. The aluminum housing is not weather or dust proof but it provides protection against foreign objects. It must be powered with an external +8 to 24VDC power source supplying at least 300 mA @ 12VDC exclusive of any remote preamplifier or antenna control device.

Modifications
The following modifications can be made to enhance functionality. These involve PCB soldering — work must be done only by a qualified person experienced in SMD soldering. Use only a light-duty (25W or less) soldering iron. DO NOT use a soldering gun.
5VDC Operation from Separate Supply
Add a soldered jumper from D2 cathode to D3 anode to bypass the 12V→4V switching regulator. Use a separate 5VDC regulated supply rated for at least 1A.
5VDC Operation from Computer USB3 Port
If a USB3 port is available, the 5VDC Vbus (900 mA available, MiniTiouner needs ~700 mA) can power the unit, eliminating the external supply. Add the jumper from R27 to the DC power jack center pin in addition to the D2–D3 jumper above.
WARNING: After these modifications, applying +12V to the DC power jack would damage both the MiniTiouner-Express AND the connected computer. Cover or disable the DC jack.
