BOM review and component selection for an nRF52840 board

I checked the full bill of materials of an nRF52840 board against the schematic and footprints, reviewed component values and added a distributor part number for every part, ready for assembly.

Bill of materials table with references, values, footprints and part numbers, blurred to keep client details private

The problem

The client had a board built around an nRF52840 module, with battery charging, a haptic driver, touch sensing, an IMU and external flash. Before assembly, they needed a bill of materials (BOM) they could trust.

What I did

  • Checked every part in the BOM against the schematic and the footprints.
  • Reviewed component values on the power circuits and changed them where needed.
  • Added a distributor part number for every part to be assembled.
  • Marked the parts that are not fitted (DNP), so the manufacturer assembles the right version of the board.

The result

A verified BOM, ready for the manufacturer’s assembly service. Client and application details are kept private under NDA.
