Mine seems running at about 0.13A with spikes at 0.4A… I will check again this afternoon.

Pure coincedence… I sticked that same antenna on a the metal enclosure from an HDMI switch and look,
So the groundplane is very important for the swr

These mSATA to USB adapter boards for Raspberry Pi still require a USB cable for it’s IO interface (and power). Although the model shown above has a compact USB to USB (PCB) adapter, many of these solutions require an external USB to USB cable (and €50 is rather expensive for 120GB when compared to below solution).

A regular cheap(er) 2.5" SATA SSD 120GB with USB 2.0 to SATA adapter can be had for around €20 (240GB for around €30). Works just as well. Although you will need to find a solution for mounting the 2.5" SSD. (I have one taped onto a Raspberry Pi enclosure which hangs in the meter cupboard.)

For more compact single enclosure solutions the SSD PCB can be removed from its 2.5" drive enclosure (which will void warranty) and use a PCB-only USB to SATA adapter with a small USB cable.

no, found it :wink:
but you’re right, it can be done cheaper of course but this HW is for a ‘special’ project

With solution for mounting I had something different in mind than ‘putting it somewhere on a table’. :wink:
