Rev A — spec handoff + Objective 1 sourcing

Thought for 41 sec

Final BOM completion is done with zero missing-MPN rows. J3 and BZ1 remain on PCB and are excluded from PCBA placement.

No Basic-class exact match was available for 1.78 kΩ, 3.01 kΩ, 90.9 kΩ, 3.48 kΩ, 178 kΩ, and 10 µF; Extended parts were assigned. Note: C14’s sourcing metadata is 0603, while its existing physical footprint remains 0805 because layout changes were prohibited.

tell me exactly out of the display header pins which one is meant for which pin on the 1.54 inch waveshare e ink display

Thought for 26 sec

flux

The J3 display header is wired in the standard Waveshare 1.54-inch e-paper cable order:

Table

J3 pin	Board net	Waveshare display pin
1	`3V3_SYS`	VCC
2	`GND`	GND
3	`SPI2_MOSI`	DIN
4	`SPI2_SCK`	CLK
5	`EPD_CS`	CS
6	`EPD_DC`	DC
7	`EPD_RST`	RST
8	`EPD_BUSY`	BUSY

So the connection is 1→VCC, 2→GND, 3→DIN, 4→CLK, 5→CS, 6→DC, 7→RST, 8→BUSY.

This assumes pin 1 is identified from the PCB footprint’s pin-1 marker. Do not determine pin 1 solely by viewing the header from the cable side, because the apparent order reverses when viewed from the opposite face.

Final BOM Completion Report

Status

Completed: BOM/PCBA metadata pass for R1–R17, C10, C11, C13–C23, and C25.
Completed: J3 and BZ1 remain on PCB; both are excluded from pick-and-place. J3 assembly note records that the owner will fit a right-angle header by hand.
Completed: MP1/MP2 remain on PCB and are excluded from BOM and pick-and-place as non-assembly solder-pad interfaces.
Completed: Existing final DRC status was read only; no open error/warning was reported for airwires, overlapping copper, missing footprints, or invalid layers.
Completed: JLC BOM and corrected JLC CPL generated and held. ORDER HELD — no order placed.

The selected 50V capacitor ratings preserve or exceed every listed component's existing 10V/16V rating.

C14's sourcing metadata is 0603/1608, while its existing generic physical Package remains SMD_0805_2012Metric; this was intentionally retained because the delegated scope prohibited footprint-geometry/layout changes.

PCBA Exclusions

J3: Exclude from Pick & Place = true; Exclude from BOM = true; remains physically on PCB. Assembly note: owner will fit a right-angle header by hand.
BZ1: Exclude from Pick & Place = true; remains in BOM with TMB12A03 / C96222 and physically on PCB.
MP1, MP2: Exclude from Pick & Place = true; Exclude from BOM = true; remain physically on PCB as motor flying-lead solder pads.
Corrected CPL contains no J3, BZ1, MP1, or MP2 rows and preserves the other existing assembly exclusions.

Export Validation

JLC BOM is non-empty: header plus 36 populated data rows.
Zero missing Manufacturer Part Number rows: the JLC BOM Comment/MPN field is populated on every exported data row.
Corrected JLC CPL is non-empty: header plus populated placement rows.
Corrected CPL was derived from the newly generated JLC pick-and-place export solely to remove the incorrectly emitted BZ1 row; no coordinates, rotations, layers, footprints, nets, traces, vias, planes, or rules were modified.
