Solder the surface mount SD Card holder onto the board. Use the Drag Solder technique
- Once on, check continuity of all connections. Fixing this after the BluePill is on will be difficult.
- Ensure the SD card fits and you dont have too much solder on the sides or contacts - if you do, you can use solder wick to clean some off
Solder the diode to the bottom of the board, ensure it is as flush with the PCB as possible. Trim the excess legs

Solder the header pins on to the BluePill. Then BluePill pill to the BlueSCSI PCB.
- Correct orientation is having the USB connector of the BluePill should be over the SD Card holder.
- NOTE: Consider adding headers to the board if you would like to have the BluePill removable.
Solder on the resistor nets. Pin one is marked on the board and the resistors.
- 220 RNETS (RN1 & RN3) are closest to the BluePill - NOTE PIN one on each - they are opposite of eachtoher. See photo.
- 330 RNETS (RN2 & RN4) are furthest from the BluePill - NOTE PIN one on each - they are opposite of eachtoher. See photo.
Solder on the Termination Jumpers & place the jumpers on to enable Termiation
Solder the 50 Pin headers on.
- Note Pin 1 and Box header on the silk screen.
Solder on the berg connector. Only needed if your machine does not supply enough power via the SCSI bus, but recommended to solder on if you have the connector
Not recommended anymore - Solder on the debug headers near the SD card. Only needed for debugging, requires a special firmware. Headers have been removed from the new PCB revisions

Plug it into your favorite Mac, run a benchmark with SCSI Director Pro, play some Lemmings, write a document in ClarisWorks, enjoy!

Note on Right angle connectors - Right angle connectors are not notched the correct way, PCB rev 1.1 fixes that Optional
