Solder on the surface mount SD Card holder. Use the [Drag Solder](https://youtu.be/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 -2. Solder the diodes to the **bottom** of the board. Be sure they are flush as possible to the bottom. -![Diode Orientation](images/diodes.png) -3. 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. -4. 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.

Note Pin 1 and Box header on the silk screen. -7. Optional - Solder on the berg connector. Only needed if your machine does not supply enough power via the SCSI bus. -8. Optional - Solder on the debug headers near the SD card. Only nessissarry if re-programming. - -### Fully Assembled -![Fully Assembled](images/assembled.png) - -### Version 1.0-b & 1.0-c BOM - -#### Mouser Cart - -https://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=c5cc83feff - -#### Parts - -STM32F103C8T6 (U1) aka BluePill board.
