EVA-M8M Pin Review


Updated the EVA-M8M-0 schematic terminal metadata directly: Power is ordered first/top, Ground last/bottom, Reserved/NC grouped before Ground, and all other pins are grouped into RF/Antenna, Host Interfaces, RTC/Control, and SQI Flash with balanced left/right orientation. I verified all 43 pins remain present with their original pin numbers; no pins were replaced, renumbered, or remapped.
Open items:
  • Earlier review findings are documented in EVA-M8M-0 Part Validation Report.
  • Pin electrical types/descriptions are still not populated; I only changed section/orientation/order as requested.
Suggested next steps:
  1. Populate datasheet-backed Pin Type and Pin Description fields.
  2. Clean up part metadata mismatches flagged in the report.
  3. Run a final visual check of the regenerated symbol layout.
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. Place Power pins first and Ground pins last. Within each section, distribute the pins between the left and right sides as evenly as possible; 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 one side as appropriate. Keep the symbol compact and balanced. If a pin function is unclear, assign Unclear / Check datasheet, then apply all changes directly to the schematic component.
I’ll rebalance the existing pin organization so every section is split left/right as evenly as possible, while preserving all 43 pin names and numbers exactly.
Updated the EVA-M8M-0 schematic component directly. All 43 existing pins are still present with the same pin numbers/names; I changed only Section, Pin Group, Pin Orientation, and Terminal Order.
Open items:
  • No unclear pins were found against the datasheet, so no pins were assigned Unclear / Check datasheet.
  • Pin Type / Pin Description fields remain unchanged because this request was only for orientation, section, and order.
Suggested next steps:
  1. Visually inspect the regenerated symbol for compactness.
  2. Populate datasheet-backed Pin Type and Pin Description metadata.
  3. Clean up the remaining part metadata issues noted in the validation report.
