Part Review and Datasheet Verification


I’ll update each terminal with datasheet-based pin metadata: number, name/designator, type, functional group/section, and description, then verify the schematic properties.
Metadata was applied; I’m normalizing a few fields to Flux standard property names/options where possible while keeping the datasheet grouping intent.
Added datasheet-based metadata to all 22 E04-400M16S terminals and verified the updates. Each pin now has Pin Number, Pin Role/name, Pin Type, Pin Group, Section, and Pin Description; I used one primary group per pin and normalized pin types to Flux standard values where available.
Open items:
  • The symbol is still represented as 22 separate Terminal components rather than one module component.
  • SPI MISO/MOSI directions follow the EBYTE datasheet wording, which should be rechecked against host/module convention during integration.
Suggested next steps:
  1. Convert these terminals into a single 22-pin module symbol.
  2. Correct and verify the footprint pad coordinates against the official EBYTE package.
  3. Add VCC decoupling and RF/antenna layout constraints.
