Part Audit Scope
Audit of the Quectel EC200U part metadata, 144-terminal schematic symbol, and 144-pad PCB footprint against official Quectel documentation.
Authoritative sources Metadata review Key specifications
Audit complete. The 144-pin numbering and general footprint topology are correct, but all pin descriptions/types are missing and the 80 perimeter pads are 0.8 × 1.0 mm instead of Quectel’s recommended 0.8 × 2.5 mm; several pin names also differ. The Datasheet property was not changed because it was already populated, and I filed a part-quality report.
Full findings: Part Audit.
Check this schematic component against the datasheet for [MPN] and assign the correct pin orientation, section, and terminal order without changing, replacing, renumbering, or remapping any pins. Remove the Pin Group property from all pins if it exists. Place Power pins first and Ground pins last. Within each section, distribute the pins as evenly as possible between the left and right sides; for example, split 10 pins as 5/5 and 11 pins as 5/6 or 6/5. If a section contains only one pin, leave it on the most appropriate side. Keep the symbol compact, balanced, and visually symmetrical. If a pin function is unclear, assign Unclear / Check datasheet, then apply all changes directly to the schematic component.
I’ll use the current part’s MPN (EC200U), verify every terminal against the official Quectel datasheet, then assign sections, orientation, and terminal order while preserving all pin numbers and mappings.
Reorganized all 144 EC200U terminals into balanced functional sections, with power first and 43 ground pins last. Removed every Pin Group property and assigned each pin a section, left/right orientation, and unique terminal order.
All original pin names, numbers, and footprint mappings were preserved. Seven reserved or ambiguous pins were placed in Unclear / Check datasheet.
