How to make a bill of materials (BOM) for an electronics project
A bill of materials (BOM) is the complete parts list a design needs to be built: every component with its quantity, a reference, and where to buy it. To make one manually, go through your schematic and list each part with a manufacturer part number, quantity, and a supplier. The fast way: describe your project in Forge Design and it generates an orderable BOM automatically — the parts are real and in a live catalog, so you can order them straight away.
What a good BOM includes
Per line: the component (e.g. "ESP32 dev board"), quantity, a reference designator where relevant (R1, C3), a manufacturer/part number so it is unambiguous, and a supplier + price. That is enough to actually order and build without guesswork.
The manual way
Work through the schematic component by component, group identical parts, assign part numbers from a distributor, and total the quantities. A spreadsheet is fine. The tedious part is finding real, in-stock parts and prices for each line.
The fast way
Forge Design produces the BOM for you from a plain-English description of the product — choosing parts from a live catalog and pricing them in naira — so the "find real parts" step is already done and the list is orderable in one click.
