Building
- Solder on the surface mount SD Card holder. 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
- Solder the dioeds to the bottom of the board. Be sure they are flush as possible to the bottom.

- 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.
- 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.
- Optional - Solder on the berg connector. Only needed if your machine does not supply enough power via the SCSI bus.
- Optional - Solder on the debug headers near the SD card. Only nessissarry if re-programming.
