Argon Pod USB-SATA module

1

Hi,

I’ve just built an USB-SATA module for Argon Pod system.

  • assembled into an USB-LAN module case
  • using cheap USB to SATA adapter (Axagon ADSA-1S)
  • can be used with half size slim SATA SSD

It can be stacked with all the Argon Pod modules
(Unfortunately I don’t have another USB-LAN case, but it works… :wink: )

It can even boot from the SATA drive without an SD Card.
All you have to do is to connect the micro USB connector’s OTG sense pin to ground (in the USB-HDMI module).

The SATA SSD is much faster and much more reliable storage than the SD card, just be sure to use at least 5V/2.5A power adatper.
