# Before you start
Read through all instructions before starting.
Verify you have all the components
* Preprogrammed STM32 BluePill with 2x 20 pin headers
* BlueSCSI 1.1 desktop PCB
* 2x Diodes
* 50 pin male SCSI connector
* 2x 220ohm Resistor Networks
* 2x 330ohm Resistor Networks
* MicroSD Socket
* Berg connector
* 2x 2 pin headers with jumpers
* 2x 2 pin headers for LEDs(optional)
* 2x resistors for LEDs(optional)
* 3d printed bracket

1. Solder the surface mount SD Card holder onto the board. Use the [Drag Solder](https://www.youtube.com/watch?v=Z_KL4fWOMug) 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
2. Solder the 2 diode to the board, ensure it is as flush with the PCB as possible. Trim the excess legs
3. Solder on the resistor nets ensuring correct placement and orientation
4. Solder on the Termination Jumpers & place the jumpers on to enable Termination
5. Solder the 50 Pin headers on.
* Note Pin 1 and Box header on the silk screen.
6. 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
7. Optional - solder on resistors for the LED for both power and activity.
8. Optional - Solder on 2 pin headers for the LED
9. 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 facing AWAY from the SD holder.
* **NOTE:** Consider adding headers to the board if you would like to have the BluePill removable.

9. [Configure it](https://github.com/erichelgeson/BlueSCSI/wiki/Usage)
10. Test it!
* Plug it into your favorite Mac, run a benchmark with SCSI Director Pro, play some Lemmings, write a document in ClarisWorks, enjoy!
*Work in progress*
