Note that the images in these instructions are taken from an assembly of the v2.0.1 board. There are minimal differences between v2.0.1 and v2.0.3 - such that it wasn't worth doing another photoshoot for v2.0.3. Make sure to follow the written instructions when in doubt.

Check out the [BOM documents](control_board/BOM/v2.0.3)

All parts referenced in these instructions use the schematic "reference designator" from the silk screen on the pcbs. E.g. "C1", "J2", and "R28". You should look up the details of these parts within the [v2.0.3 BOM the board ref parts spreadsheet](control_board/BOM/v2.0.3/bom_v2.0.3_board_ref_parts.csv) or the [v2.0.3 BOM other parts spreadsheet](control_board/BOM/v2.0.3/bom_v2.0.3_other_parts.csv). This will tell you the unique ID of the part that we use for ordering from Digikey + elsewhere, and will also link to pictures of the part on the relevant website.

You should look up the details of these parts within the [v2.0.3 BOM the board ref parts spreadsheet](control_board/BOM/v2.0.3/bom_v2.0.3_board_ref_parts.csv), using the "Reference" column. There are additional parts in the [v2.0.3 BOM other parts spreadsheet](control_board/BOM/v2.0.3/bom_v2.0.3_other_parts.csv), which do not correspond to reference designators on the board. These spreadsheets also have unique IDs (UIDs) that we use for ordering from Digikey + elsewhere, and link to details of the parts on the relevant websites.

Generally these instructions have enough images to clearly show and identify the parts, but whenever in doubt the best thing to do is to look up the reference in the BOM spreadsheet.
