Supply Termination Power
The SCSI2SD V5.1 and V6 boards can be modified to supply termination power back to the SCSI cable.
SMD soldering solution
- The pins at JP201 needs to be shorted. It's designed for a standard 0.1" jumper, but you could just put a paperclip in those pin holes.
- Add a schottky diode to D205 (SOD-123 package). The diode needs to be rated for at least 1A continuous current
- Try MBRX120LF-TP
- Alternatively, desolder D203 and move it to D205.
