Notes:





U3 not used
U11, R17, R18, C8, C9, C17, P4 normally not installed so quantity 0. R17, R18 were 5.1k, C17 was .1uf.
R24 should be 3.32k and R25 82.5k when a LDO03H is used for U12. Schematic values are out of date. If OKR-T/1.5-W12-C is used R24 and R25 don't normally need to be installed but is ok to always install. If Beaglebone does not reliably power up install 1K for R24 and 5.1K for R25. Also for OKR-T/1.5-W12-C C7,C8,C9 need to be installed. For LDO03H only C7 needed. With BOM R24,R25 LDO03H starts up at about 7.7V and shuts down at 5.6V.







Capacitor notes:




For C1-C5 there is a trade off between how well the capacitors fit and run time. The current primary capacitor will fit in ½ height bay with capacitors mounted on bottom of board. The alternate choices will not unless installed laying down. During testing 3F is not sufficient if any significant amount of data waiting write-back to flash. 5F should be OK but capacity loss with aging may be a concern. No great reason to use these options but left here anyway.

You may also want to purchase parts for drive activity LED. Order 1 or 2 more of the LED's on the BOM depending on the number of drives you plan to emulate. If you are wanting to put them in the existing faceplate you may need rectangular LEDs. Since the BBB only provides 6mA you may wish them to be high efficiency. Order 1 more of the 267 ohm resistors. If you want LED's brightest order 215 or 220 ohm resistor.







You will need a cable to plug into J7 unless you don't install J7 and solder to board. One option is cut up a pre-built ribbon cable.
Also these cables should work for the second data cable for J6 for two drive emulation.

You can also buy discrete wire housings and contacts. They can be difficult to crimp without the proper tool. I solder when needed for reliable joint. Buy extra since you are likely to damage one.
