So I was quite busy yesterday trying to get the SATA port working, task that has been quite unsuccessful so far...
I took a photo of the PCB to show the various points of interest:
Without soldering anything yet, I took a few voltage mesurements on the various pins:
- (1) : 1.55V
- (2) : -1.75V
Both mesurements are relative to (3), the ground pin.
Of course, at this stage, I'm surprised because I was expecting 3.3V on pin (1), as per the schematic:
So if anyone has an explanation, because I don't understand these readings.
PS: for those looking to purchase a eSATA connector: try eBay, there are loads of very cheap (5-6 euros including postage) USB->eSATA dongles for sale. Should be pretty easy to unsolder the eSATA port...
