[v1.1](v1.1) is working well so I don't expect any majour changes for a while.
|
||
|
|
|
||
|
|
## v1.2 (possible maintenance version)
|
||
|
|
|
||
|
|
Plans for a v1.2 (maintenance) may include:
|
||
|
|
|
||
|
|
* Jumper to toggle the activity LED
|
||
|
|
- So you can solder the LED and resistor, but disable it later if you prefer
|
||
|
|
* Break out power LED
|
||
|
|
- Provide a power LED (and a jumper toggle) breakout if an external power LED is desired
|
||
|
|
* Replace J4 & J5 with DIP switches or a single DPDT switch
|
||
|
|
|
||
|
|
## v2.0 (possible full redesign)
|
||
|
|
|
||
|
|
If I continue to develop project in the future, I plan on a full redesign.
|
||
|
|
|
||
|
|
* Use termination ICs instead of resistors
|
||
|
|
- Lower power consumption
|
||
|
|
- More accurate termination voltage
|
||
|
|
- Switchable termination resistance (110-ohm or 2.5k-ohm) for short busses
|
||
|
|
* Attach J1 & J2 via the PCB edge to make it more like how an actual hard drive connects
|
||
|
|
* Less-expensive Micro SD card slot
|
||
|
|
* Automatic switching between TERMPWR, MOTORPWR or USB Power
|
||
|
|
|
||
|
|
If I want to fork the actual BlueSCSI firmware, I would like to add:
|
||
|
|
|
||
|
|
* Separate LEDs for read and write activity
|
||
|
|
* Read TERMPWR and MOTORPWR voltages and report them on the debugging connector
|
||
|
|
* LEDs to indicate with SCSI ID is being accessed
|
||
|
|
* Support OLED debugging display
